Understanding CloudWatch RUM

CloudWatch Real-User Monitoring (RUM) is a monitoring functionality facilitated by CloudWatch which has always been the monitoring tool on AWS. RUM enables developers and DevOps engineers to understand the issues/errors encountered on the web-app and also insights such as which device or browser or location had the error. Additionally, there is performance insights and the time taken for a file to load on the client side along with the geographically information.
As Jeff Barr quotes it, it’s that simple to implement on the client side.

You simply register your application, add a snippet of JavaScript to the header of each page, and deploy.

The CloudWatch RUM consolidated and provides dashboard which gives you a detailed insights such as – page load speed, geographic info, devices, browsers, average load during the time, user journey. All this with just a snippet of JS to page.



Setting-up RUM

CloudWatch Real-User Monitoring (RUM) setup can be summarized with the 3 steps –



Add app monitor

While adding a new app monitor, you would have to specify details such as – app monitor name, app domain and an option to include the sub-domains of the app domain.
You can choose what all data is been collected and stored as telemetry data for the dashboards.
Configs
The telemetry data is stored only for 30 days, so if you would wish to store the logs, you can create a CloudWatch log event which captures and stores all these datas.
Data storage
CloudWatch RUM needs authorization to access AWS resources, for which Amazon Cognito Identity Pools are used.
Authorization
The telemetry data of the web-pages can also be fine grained to the choice of all pages, specific pages only or exclude certain pages.
Configure pages



Adding the JS snippet to your web app

Once you save the configurations and add the app monitor, you would be presented with a JavaScript snippet.
JS snippet
As simple as it is, this just needs to be added to the <head> of your web-page which is sending telemetry data using the <script> tag.



Monitor the web-app from CloudWatch console

Once set-up and moved your web-page to the server, you can navigate to your CloudWatch console to view the dashboard.

Wrap-up

CloudWatch RUM has provided a simplistic approach to web-app insights. The above sample logs and telemetry data are of my personal landing page https://zachjonesnoel.com which has been up and running from Dec 01 2021 and this dashboard has facilitated me to understand what and how is the performance.
