Add metrics to Dashboard

Now that we have a dashboard for our Linux EC2 instance, we can add an additional metric for available memory.

1. Let’s add a new widget to our CloudWatch Dashboard. Click on the “Add Widget” button in the upper right corner.
2. Click Line, then next
3. Click Metrics and then Configure
4. Select “PerfLab” under Custom Namespaces and then select the second metric group “ImageId, InstanceId, InstanceType”
5. Make sure to search only for the InstanceId if you have multiple machines reporting metrics
6. Find the “mem_used” and “mem_total” and click the check box next to it
7. Click on “Graphed Metrics (2)” and then select “5 seconds” as the period
8. Click on Create widget
9. You should now see two widgets on your Dashboard
10. You can drag the widgets around the screen and re-size them if you wish
11. You can also change the time period, select 1h to show just the most recent metrics
12. You can also set the auto-refresh rate for the Dashboard by using this pull-down. Select 10s
13. Click the “Save Dashboard” button before proceeding to the next step.
