	// The metric for which you want to return information. Valid instance metric
	// names are listed below, along with the most useful statistics to include in
	// your request, and the published unit value.
	//   - BurstCapacityPercentage - The percentage of CPU performance available for
	//   your instance to burst above its baseline. Your instance continuously accrues
	//   and consumes burst capacity. Burst capacity stops accruing when your instance's
	//   BurstCapacityPercentage reaches 100%. For more information, see Viewing
	//   instance burst capacity in Amazon Lightsail (https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-viewing-instance-burst-capacity)
	//   . Statistics : The most useful statistics are Maximum and Average . Unit : The
	//   published unit is Percent .
	//   - BurstCapacityTime - The available amount of time for your instance to burst
	//   at 100% CPU utilization. Your instance continuously accrues and consumes burst
	//   capacity. Burst capacity time stops accruing when your instance's
	//   BurstCapacityPercentage metric reaches 100%. Burst capacity time is consumed
	//   at the full rate only when your instance operates at 100% CPU utilization. For
	//   example, if your instance operates at 50% CPU utilization in the burstable zone
	//   for a 5-minute period, then it consumes CPU burst capacity minutes at a 50% rate
	//   in that period. Your instance consumed 2 minutes and 30 seconds of CPU burst
	//   capacity minutes in the 5-minute period. For more information, see Viewing
	//   instance burst capacity in Amazon Lightsail (https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-viewing-instance-burst-capacity)
	//   . Statistics : The most useful statistics are Maximum and Average . Unit : The
	//   published unit is Seconds .
	//   - CPUUtilization - The percentage of allocated compute units that are
	//   currently in use on the instance. This metric identifies the processing power to
	//   run the applications on the instance. Tools in your operating system can show a
	//   lower percentage than Lightsail when the instance is not allocated a full
	//   processor core. Statistics : The most useful statistics are Maximum and
	//   Average . Unit : The published unit is Percent .
	//   - NetworkIn - The number of bytes received on all network interfaces by the
	//   instance. This metric identifies the volume of incoming network traffic to the
	//   instance. The number reported is the number of bytes received during the period.
	//   Because this metric is reported in 5-minute intervals, divide the reported
	//   number by 300 to find Bytes/second. Statistics : The most useful statistic is
	//   Sum . Unit : The published unit is Bytes .
	//   - NetworkOut - The number of bytes sent out on all network interfaces by the
	//   instance. This metric identifies the volume of outgoing network traffic from the
	//   instance. The number reported is the number of bytes sent during the period.
	//   Because this metric is reported in 5-minute intervals, divide the reported
	//   number by 300 to find Bytes/second. Statistics : The most useful statistic is
	//   Sum . Unit : The published unit is Bytes .
	//   - StatusCheckFailed - Reports whether the instance passed or failed both the
	//   instance status check and the system status check. This metric can be either 0
	//   (passed) or 1 (failed). This metric data is available in 1-minute (60 seconds)
	//   granularity. Statistics : The most useful statistic is Sum . Unit : The
	//   published unit is Count .
	//   - StatusCheckFailed_Instance - Reports whether the instance passed or failed
	//   the instance status check. This metric can be either 0 (passed) or 1 (failed).
	//   This metric data is available in 1-minute (60 seconds) granularity. Statistics
	//   : The most useful statistic is Sum . Unit : The published unit is Count .
	//   - StatusCheckFailed_System - Reports whether the instance passed or failed the
	//   system status check. This metric can be either 0 (passed) or 1 (failed). This
	//   metric data is available in 1-minute (60 seconds) granularity. Statistics :
	//   The most useful statistic is Sum . Unit : The published unit is Count .
	//   - MetadataNoToken - Reports the number of times that the instance metadata
	//   service was successfully accessed without a token. This metric determines if
	//   there are any processes accessing instance metadata by using Instance Metadata
	//   Service Version 1, which doesn't use a token. If all requests use token-backed
	//   sessions, such as Instance Metadata Service Version 2, then the value is 0.
	//   Statistics : The most useful statistic is Sum . Unit : The published unit is
	//   Count .

	// The statistic for the metric. The following statistics are available:
	//   - Minimum - The lowest value observed during the specified period. Use this
	//   value to determine low volumes of activity for your application.
	//   - Maximum - The highest value observed during the specified period. Use this
	//   value to determine high volumes of activity for your application.
	//   - Sum - All values submitted for the matching metric added together. You can
	//   use this statistic to determine the total volume of a metric.
	//   - Average - The value of Sum / SampleCount during the specified period. By
	//   comparing this statistic with the Minimum and Maximum values, you can determine
	//   the full scope of a metric and how close the average use is to the Minimum and
	//   Maximum values. This comparison helps you to know when to increase or decrease
	//   your resources.
