Describe the enhancement:
We added the awesome elastic agent integration in 7.11 that shows agent metrics and filebeat and metricbeat system metrics. There are other meaningful filebeat and metricbeat metrics that we gather but are not showing it on dashboard today. These metrics are displayed in stack monitoring UI and are described in our documentation

Acceptance criteria:
After this issue is resolved, users will be able to see all the filebeat and metricbeat metrics that we display in stack monitoring UI.

@ravikesarwani I do not specific metric names other than the ones in documentation. If there are additional metrics not shown but we need to show in dashboard, can you please add them in this issue?
