You are able to evaluate real-user experiences and latency with the test. - If you are using Amazon CloudWatch RUM, it is able to analyze end-user traffics inside the AWS Console Dashboard. - Move to CloudWatch Console. (us-east-1) - Click the RUM button from the Application Monitoring tab on the left side. - Click the buttonAdd App Monitor, and start App Monitoring. - In this sample, we are going to integrate CloudWatch RUM into Matchmaker. Input App Monitor Name and Application Domain as follows: ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-appmonitor.png) - You should input Top Level Domain(TLD) into Application Domain. Please check whether domain is correct. - Collect Performance metrics, Javascript errors and so on. ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-metric.png) - CloudWatch RUM manages User Sessions using Amazon Cognito. Create new Identity Pool as follows: ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-cognito.png) - Click the button Add App Monitor, and create App Monitor. - Copy Javascript Snippets from the console, and paste on our source code(/webcardmatch/views/index.html). You should put it inside tag. This should be the upper most tag in the source code. ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-snippet.png) - Redeploy the index.html source code on the Matchmaker EC2 instance. - Restart the game match. Now we are able to monitor the application using CloudWatch RUM. ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-rum1.png) - It is able to monitor real-user performance and end-user session information. ![RUM](https://d1zrwss8zuawdm.cloudfront.net/webcard21-rum2.png) - In this sample, I set CloudWatch RUM into matchmaker, but you are able to set it for application server side.
