You can use Amazon CloudWatch Logs to monitor, store, and access your log files from EC2 instances, CloudTrail, and other sources. You can then retrieve the associated log data from CloudWatch Logs using the CloudWatch console. Alternatively, you can use CloudWatch Logs commands in the Amazon Web Services CLI, CloudWatch Logs API, or CloudWatch Logs SDK.

You can use CloudWatch Logs to:

• Monitor logs from EC2 instances in real time: You can use CloudWatch Logs to monitor applications and systems using log data. For example, CloudWatch Logs can track the number of errors that occur in your application logs. Then, it can send you a notification whenever the rate of errors exceeds a threshold that you specify. CloudWatch Logs uses your log data for monitoring so no code changes are required. For example, you can monitor application logs for specific literal terms (such as "NullReferenceException"). You can also count the number of occurrences of a literal term at a particular position in log data (such as "404" status codes in an Apache access log). When the term you are searching for is found, CloudWatch Logs reports the data to a CloudWatch metric that you specify.

• Monitor CloudTrail logged events: You can create alarms in CloudWatch and receive notifications of particular API activity as captured by CloudTrail. You can use the notification to perform troubleshooting.

• Archive log data: You can use CloudWatch Logs to store your log data in highly durable storage. You can change the log retention setting so that any log events earlier than this setting are automatically deleted. The CloudWatch Logs agent helps to quickly send both rotated and non-rotated log data off of a host and into the log service. You can then access the raw log data when you need it.

Associates the specified KMS key with either one log group in the account, or with all stored CloudWatch Logs query insights results in the account.

When you use AssociateKmsKey, you specify either the logGroupName parameter or the resourceIdentifier parameter. You can\'t specify both of those parameters in the same operation.

• Specify the logGroupName parameter to cause all log events stored in the log group to be encrypted with that key. Only the log events ingested after the key is associated are encrypted with that key.

  Associating a KMS key with a log group overrides any existing associations between the log group and a KMS key. After a KMS key is associated with a log group, all newly ingested data for the log group is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.

  Associating a key with a log group does not cause the results of queries of that log group to be encrypted with that key. To have query results encrypted with a KMS key, you must use an AssociateKmsKey operation with the resourceIdentifier parameter that specifies a query-result resource.

• Specify the resourceIdentifier parameter with a query-result resource, to use that key to encrypt the stored results of all future StartQuery operations in the account. The response from a GetQueryResults operation will still return the query results in plain text.

  Even if you have not associated a key with your query results, the query results are encrypted when stored, using the default CloudWatch Logs method.

  If you run a query from a monitoring account that queries logs in a source account, the query results key from the monitoring account, if any, is used.

It can take up to 5 minutes for this operation to take effect.

If you attempt to associate a KMS key with a log group but the KMS key does not exist or the KMS key is disabled, you receive an InvalidParameterException error.

Cancels the specified export task.

The task must be in the PENDING or RUNNING state.

Creates an export task so that you can efficiently export data from a log group to an Amazon S3 bucket. When you perform a CreateExportTask operation, you must use credentials that have permission to write to the S3 bucket that you specify as the destination.

Exporting log data to S3 buckets that are encrypted by KMS is supported. Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled with a retention period is also supported.

Exporting to S3 buckets that are encrypted with AES-256 is supported.

This is an asynchronous call. If all the required information is provided, this operation initiates an export task and responds with the ID of the task. After the task has started, you can use DescribeExportTasks to get the status of the export task. Each account can only have one active (RUNNING or PENDING) export task at a time. To cancel an export task, use CancelExportTask.

You can export logs from multiple log groups or multiple time ranges to the same S3 bucket. To separate log data for each export task, specify a prefix to be used as the Amazon S3 key prefix for all exported objects.

Creates a log group with the specified name. You can create up to 20,000 log groups per account.

You must use the following guidelines when naming a log group:

• Log group names must be unique within a Region for an Amazon Web Services account.

• Log group names can be between 1 and 512 characters long.

• Log group names consist of the following characters: a-z, A-Z, 0-9, \'_\' (underscore), \'-\' (hyphen), \'/\' (forward slash), \'.\' (period), and \'#\' (number sign)

When you create a log group, by default the log events in the log group do not expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy.

If you associate an KMS key with the log group, ingested data is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.

If you attempt to associate a KMS key with the log group but the KMS key does not exist or the KMS key is disabled, you receive an InvalidParameterException error.

Creates a log stream for the specified log group. A log stream is a sequence of log events that originate from a single source, such as an application instance or a resource that is being monitored.

There is no limit on the number of log streams that you can create for a log group. There is a limit of 50 TPS on CreateLogStream operations, after which transactions are throttled.

You must use the following guidelines when naming a log stream:

• Log stream names must be unique within the log group.

• Log stream names can be between 1 and 512 characters long.

• Don\'t use \':\' (colon) or \'*\' (asterisk) characters.

Deletes a CloudWatch Logs account policy.

To use this operation, you must be signed on with the logs:DeleteDataProtectionPolicy and logs:DeleteAccountPolicy permissions.

Deletes the data protection policy from the specified log group.

For more information about data protection policies, see PutDataProtectionPolicy.

Deletes the specified destination, and eventually disables all the subscription filters that publish to it. This operation does not delete the physical resource encapsulated by the destination.

Deletes the specified log group and permanently deletes all the archived log events associated with the log group.

Deletes the specified log stream and permanently deletes all the archived log events associated with the log stream.

Deletes the specified metric filter.

Deletes a saved CloudWatch Logs Insights query definition. A query definition contains details about a saved CloudWatch Logs Insights query.

Each DeleteQueryDefinition operation can delete one query definition.

You must have the logs:DeleteQueryDefinition permission to be able to perform this operation.

Deletes a resource policy from this account. This revokes the access of the identities in that policy to put log events to this account.

Deletes the specified retention policy.

Log events do not expire if they belong to log groups without a retention policy.

Deletes the specified subscription filter.

Returns a list of all CloudWatch Logs account policies in the account.

Lists all your destinations. The results are ASCII-sorted by destination name.

Lists the specified export tasks. You can list all your export tasks or filter the results based on task ID or task status.

Lists the specified log groups. You can list all your log groups or filter the results by prefix. The results are ASCII-sorted by log group name.

CloudWatch Logs doesn’t support IAM policies that control access to the DescribeLogGroups action by using the aws:ResourceTag/key-name condition key. Other CloudWatch Logs actions do support the use of the aws:ResourceTag/key-name condition key to control access. For more information about using tags to control access, see Controlling access to Amazon Web Services resources using tags.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

Lists the log streams for the specified log group. You can list all the log streams or filter the results by prefix. You can also control how the results are ordered.

You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must include one of these two parameters, but you can\'t include both.

This operation has a limit of five transactions per second, after which transactions are throttled.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

Lists the specified metric filters. You can list all of the metric filters or filter the results by log name, prefix, metric name, or metric namespace. The results are ASCII-sorted by filter name.

Returns a list of CloudWatch Logs Insights queries that are scheduled, running, or have been run recently in this account. You can request all queries or limit it to queries of a specific log group or queries with a certain status.

This operation returns a paginated list of your saved CloudWatch Logs Insights query definitions.

You can use the queryDefinitionNamePrefix parameter to limit the results to only the query definitions that have names that start with a certain string.

Lists the resource policies in this account.

Lists the subscription filters for the specified log group. You can list all the subscription filters or filter the results by prefix. The results are ASCII-sorted by filter name.

Disassociates the specified KMS key from the specified log group or from all CloudWatch Logs Insights query results in the account.

When you use DisassociateKmsKey, you specify either the logGroupName parameter or the resourceIdentifier parameter. You can\'t specify both of those parameters in the same operation.

• Specify the logGroupName parameter to stop using the KMS key to encrypt future log events ingested and stored in the log group. Instead, they will be encrypted with the default CloudWatch Logs method. The log events that were ingested while the key was associated with the log group are still encrypted with that key. Therefore, CloudWatch Logs will need permissions for the key whenever that data is accessed.

• Specify the resourceIdentifier parameter with the query-result resource to stop using the KMS key to encrypt the results of all future StartQuery operations in the account. They will instead be encrypted with the default CloudWatch Logs method. The results from queries that ran while the key was associated with the account are still encrypted with that key. Therefore, CloudWatch Logs will need permissions for the key whenever that data is accessed.

It can take up to 5 minutes for this operation to take effect.

Lists log events from the specified log group. You can list all the log events or filter the results using a filter pattern, a time range, and the name of the log stream.

You must have the logs:FilterLogEvents permission to perform this operation.

You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must include one of these two parameters, but you can\'t include both.

By default, this operation returns as many log events as can fit in 1 MB (up to 10,000 log events) or all the events found within the specified time range. If the results include a token, that means there are more log events available. You can get additional results by specifying the token in a subsequent call. This operation can return empty results while there are more log events available through the token.

The returned log events are sorted by event timestamp, the timestamp when the event was ingested by CloudWatch Logs, and the ID of the PutLogEvents request.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

Returns information about a log group data protection policy.

Lists log events from the specified log stream. You can list all of the log events or filter using a time range.

By default, this operation returns as many log events as can fit in a response size of 1MB (up to 10,000 log events). You can get additional log events by specifying one of the tokens in a subsequent call. This operation can return empty results while there are more log events available through the token.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must include one of these two parameters, but you can\'t include both.

Returns a list of the fields that are included in log events in the specified log group. Includes the percentage of log events that contain each field. The search is limited to a time period that you specify.

You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must specify one of these parameters, but you can\'t specify both.

In the results, fields that start with @ are fields generated by CloudWatch Logs. For example, @timestamp is the timestamp of each log event. For more information about the fields that are generated by CloudWatch logs, see Supported Logs and Discovered Fields.

The response results are sorted by the frequency percentage, starting with the highest percentage.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

Retrieves all of the fields and values of a single log event. All fields are retrieved, even if the original query that produced the logRecordPointer retrieved only a subset of fields. Fields are returned as field name/field value pairs.

The full unparsed log event is returned within @message.

Returns the results from the specified query.

Only the fields requested in the query are returned, along with a @ptr field, which is the identifier for the log record. You can use the value of @ptr in a GetLogRecord operation to get the full log record.

GetQueryResults does not start running a query. To run a query, use StartQuery.

If the value of the Status field in the output is Running, this operation returns only partial results. If you see a value of Scheduled or Running for the status, you can retry the operation later to see the final results.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account to start queries in linked source accounts. For more information, see CloudWatch cross-account observability.

Displays the tags associated with a CloudWatch Logs resource. Currently, log groups and destinations support tagging.

Lists the tags for the specified log group.

Creates an account-level data protection policy that applies to all log groups in the account. A data protection policy can help safeguard sensitive data that\'s ingested by your log groups by auditing and masking the sensitive log data. Each account can have only one account-level policy.

If you use PutAccountPolicy to create a data protection policy for your whole account, it applies to both existing log groups and all log groups that are created later in this account. The account policy is applied to existing log groups with eventual consistency. It might take up to 5 minutes before sensitive data in existing log groups begins to be masked.

By default, when a user views a log event that includes masked data, the sensitive data is replaced by asterisks. A user who has the logs:Unmask permission can use a GetLogEvents or FilterLogEvents operation with the unmask parameter set to true to view the unmasked log events. Users with the logs:Unmask can also view unmasked data in the CloudWatch Logs console by running a CloudWatch Logs Insights query with the unmask query command.

For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking.

To use the PutAccountPolicy operation, you must be signed on with the logs:PutDataProtectionPolicy and logs:PutAccountPolicy permissions.

The PutAccountPolicy operation applies to all log groups in the account. You can also use PutDataProtectionPolicy to create a data protection policy that applies to just one log group. If a log group has its own data protection policy and the account also has an account-level data protection policy, then the two policies are cumulative. Any sensitive term specified in either policy is masked.

Creates a data protection policy for the specified log group. A data protection policy can help safeguard sensitive data that\'s ingested by the log group by auditing and masking the sensitive log data.

By default, when a user views a log event that includes masked data, the sensitive data is replaced by asterisks. A user who has the logs:Unmask permission can use a GetLogEvents or FilterLogEvents operation with the unmask parameter set to true to view the unmasked log events. Users with the logs:Unmask can also view unmasked data in the CloudWatch Logs console by running a CloudWatch Logs Insights query with the unmask query command.

For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking.

The PutDataProtectionPolicy operation applies to only the specified log group. You can also use PutAccountPolicy to create an account-level data protection policy that applies to all log groups in the account, including both existing log groups and log groups that are created level. If a log group has its own data protection policy and the account also has an account-level data protection policy, then the two policies are cumulative. Any sensitive term specified in either policy is masked.

Creates or updates a destination. This operation is used only to create destinations for cross-account subscriptions.

A destination encapsulates a physical resource (such as an Amazon Kinesis stream). With a destination, you can subscribe to a real-time stream of log events for a different account, ingested using PutLogEvents.

Through an access policy, a destination controls what is written to it. By default, PutDestination does not set any access policy with the destination, which means a cross-account user cannot call PutSubscriptionFilter against this destination. To enable this, the destination owner must call PutDestinationPolicy after PutDestination.

To perform a PutDestination operation, you must also have the iam:PassRole permission.

Creates or updates an access policy associated with an existing destination. An access policy is an IAM policy document that is used to authorize claims to register a subscription filter against a given destination.

Uploads a batch of log events to the specified log stream.

The batch of events must satisfy the following constraints:

• The maximum batch size is 1,048,576 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.

• None of the log events in the batch can be more than 2 hours in the future.

• None of the log events in the batch can be more than 14 days in the past. Also, none of the log events can be from earlier than the retention period of the log group.

• The log events in the batch must be in chronological order by their timestamp. The timestamp is the time that the event occurred, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. (In Amazon Web Services Tools for PowerShell and the Amazon Web Services SDK for .NET, the timestamp is specified in .NET format: yyyy-mm-ddThh:mm:ss. For example, 2017-09-15T13:45:30.)

• A batch of log events in a single request cannot span more than 24 hours. Otherwise, the operation fails.

• Each log event can be no larger than 256 KB.

• The maximum number of log events in a batch is 10,000.

• The quota of five requests per second per log stream has been removed. Instead, PutLogEvents actions are throttled based on a per-second per-account quota. You can request an increase to the per-second throttling quota by using the Service Quotas service.

If a call to PutLogEvents returns "UnrecognizedClientException" the most likely cause is a non-valid Amazon Web Services access key ID or secret key.

Creates or updates a metric filter and associates it with the specified log group. With metric filters, you can configure rules to extract metric data from log events ingested through PutLogEvents.

The maximum number of metric filters that can be associated with a log group is 100.

When you create a metric filter, you can also optionally assign a unit and dimensions to the metric that is created.

Creates or updates a query definition for CloudWatch Logs Insights. For more information, see Analyzing Log Data with CloudWatch Logs Insights.

To update a query definition, specify its queryDefinitionId in your request. The values of name, queryString, and logGroupNames are changed to the values that you specify in your update operation. No current values are retained from the current query definition. For example, imagine updating a current query definition that includes log groups. If you don\'t specify the logGroupNames parameter in your update operation, the query definition changes to contain no log groups.

You must have the logs:PutQueryDefinition permission to be able to perform this operation.

Creates or updates a resource policy allowing other Amazon Web Services services to put log events to this account, such as Amazon Route 53. An account can have up to 10 resource policies per Amazon Web Services Region.

Sets the retention of the specified log group. With a retention policy, you can configure the number of days for which to retain log events in the specified log group.

Creates or updates a subscription filter and associates it with the specified log group. With subscription filters, you can subscribe to a real-time stream of log events ingested through PutLogEvents and have them delivered to a specific destination. When log events are sent to the receiving service, they are Base64 encoded and compressed with the GZIP format.

The following destinations are supported for subscription filters:

• An Amazon Kinesis data stream belonging to the same account as the subscription filter, for same-account delivery.

• A logical destination created with PutDestination that belongs to a different account, for cross-account delivery. We currently support Kinesis Data Streams and Kinesis Data Firehose as logical destinations.

• An Amazon Kinesis Data Firehose delivery stream that belongs to the same account as the subscription filter, for same-account delivery.

• An Lambda function that belongs to the same account as the subscription filter, for same-account delivery.

Each log group can have up to two subscription filters associated with it. If you are updating an existing filter, you must specify the correct name in filterName.

To perform a PutSubscriptionFilter operation for any destination except a Lambda function, you must also have the iam:PassRole permission.

Schedules a query of a log group using CloudWatch Logs Insights. You specify the log group and time range to query and the query string to use.

For more information, see CloudWatch Logs Insights Query Syntax.

After you run a query using StartQuery, the query results are stored by CloudWatch Logs. You can use GetQueryResults to retrieve the results of a query, using the queryId that StartQuery returns.

If you have associated a KMS key with the query results in this account, then StartQuery uses that key to encrypt the results when it stores them. If no key is associated with query results, the query results are encrypted with the default CloudWatch Logs encryption method.

Queries time out after 60 minutes of runtime. If your queries are timing out, reduce the time range being searched or partition your query into a number of queries.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account to start a query in a linked source account. For more information, see CloudWatch cross-account observability. For a cross-account StartQuery operation, the query definition must be defined in the monitoring account.

You can have up to 30 concurrent CloudWatch Logs insights queries, including queries that have been added to dashboards.

Stops a CloudWatch Logs Insights query that is in progress. If the query has already ended, the operation returns an error indicating that the specified query is not running.

Adds or updates the specified tags for the specified log group.

To list the tags for a log group, use ListTagsForResource. To remove tags, use UntagResource.

For more information about tags, see Tag Log Groups in Amazon CloudWatch Logs in the Amazon CloudWatch Logs User Guide.

CloudWatch Logs doesn’t support IAM policies that prevent users from assigning specified tags to log groups using the aws:Resource/key-name or aws:TagKeys condition keys. For more information about using tags to control access, see Controlling access to Amazon Web Services resources using tags.

Assigns one or more tags (key-value pairs) to the specified CloudWatch Logs resource. Currently, the only CloudWatch Logs resources that can be tagged are log groups and destinations.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.

Tags don\'t have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the alarm, this tag is appended to the list of tags associated with the alarm. If you specify a tag key that is already associated with the alarm, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a CloudWatch Logs resource.

Tests the filter pattern of a metric filter against a sample of log event messages. You can use this operation to validate the correctness of a metric filter pattern.

Removes the specified tags from the specified log group.

To list the tags for a log group, use ListTagsForResource. To add tags, use TagResource.

CloudWatch Logs doesn’t support IAM policies that prevent users from assigning specified tags to log groups using the aws:Resource/key-name or aws:TagKeys condition keys.

Removes one or more tags from the specified resource.

An IAM policy document that governs which Amazon Web Services accounts can create subscription filters against this destination.

An IAM policy document that authorizes cross-account users to deliver their log events to the associated destination. This can be up to 5120 bytes.

The Amazon Web Services account ID that the policy applies to.

If you are using an account that is set up as a monitoring account for CloudWatch unified cross-account observability, you can use this to specify the account ID of a source account. If you do, the operation returns the account policy for the specified account. Currently, you can specify only one account ID in this parameter.

If you omit this parameter, only the policy in the current account is returned.

When includeLinkedAccounts is set to True, use this parameter to specify the list of accounts to search. You can specify as many as 20 account IDs in the array.

An array of structures that contain information about the CloudWatch Logs account policies that match the specified filters.

A structure that contains information about one CloudWatch Logs account policy.

The account policy that you created.

The policy document for this account policy.

The JSON specified in policyDocument can be up to 30,720 characters.

Specify the data protection policy, in JSON.

This policy must include two JSON blocks:

• The first block must include both a DataIdentifer array and an Operation property with an Audit action. The DataIdentifer array lists the types of sensitive data that you want to mask. For more information about the available options, see Types of data that you can mask.

  The Operation property with an Audit action is required to find the sensitive data terms. This Audit action must contain a FindingsDestination object. You can optionally use that FindingsDestination object to list one or more destinations to send audit findings to. If you specify destinations such as log groups, Kinesis Data Firehose streams, and S3 buckets, they must already exist.

• The second block must include both a DataIdentifer array and an Operation property with an Deidentify action. The DataIdentifer array must exactly match the DataIdentifer array in the first block of the policy.

  The Operation property with the Deidentify action is what actually masks the data, and it must contain the "MaskConfig": {} object. The "MaskConfig": {} object must be empty.

For an example data protection policy, see the Examples section on this page.

In addition to the two JSON blocks, the policyDocument can also include Name, Description, and Version fields. The Name is different than the operation\'s policyName parameter, and is used as a dimension when CloudWatch Logs reports audit findings metrics to CloudWatch.

The JSON specified in policyDocument can be up to 30,720 characters.

The ARN of the resource that you want to view tags for.

The ARN format of a log group is arn:aws:logs:Region:account-id:log-group:log-group-name

This policy must include two JSON blocks:

• The first block must include both a DataIdentifer array and an Operation property with an Audit action. The DataIdentifer array lists the types of sensitive data that you want to mask. For more information about the available options, see Types of data that you can mask.

  The Operation property with an Audit action is required to find the sensitive data terms. This Audit action must contain a FindingsDestination object. You can optionally use that FindingsDestination object to list one or more destinations to send audit findings to. If you specify destinations such as log groups, Kinesis Data Firehose streams, and S3 buckets, they must already exist.

• The second block must include both a DataIdentifer array and an Operation property with an Deidentify action. The DataIdentifer array must exactly match the DataIdentifer array in the first block of the policy.

  The Operation property with the Deidentify action is what actually masks the data, and it must contain the "MaskConfig": {} object. The "MaskConfig": {} object must be empty.

For an example data protection policy, see the Examples section on this page.

In addition to the two JSON blocks, the policyDocument can also include Name, Description, and Version fields. The Name is used as a dimension when CloudWatch Logs reports audit findings metrics to CloudWatch.

The JSON specified in policyDocument can be up to 30,720 characters.

The data protection policy used for this log group.

Displays whether this log group has a protection policy, or whether it had one in the past. For more information, see PutDataProtectionPolicy.

• An Amazon Kinesis stream belonging to the same account as the subscription filter, for same-account delivery.

• A logical destination (specified using an ARN) belonging to a different account, for cross-account delivery.

  If you\'re setting up a cross-account subscription, the destination must have an IAM policy associated with it. The IAM policy must allow the sender to send logs to the destination. For more information, see PutDestinationPolicy.
