What does this view show?

Several panels about how individual machines in your Splunk Enterprise deployment are using resources.

Interpret results in this view

This view can be useful for operational post mortems, as well as for capacity planning. See the Capacity Planning Manual for more information.

About physical memory usage in this view: on Linux, the OS starts using free physical memory to cache filesystem resources. But memory for this is loosely bound, and the OS frees it up if a higher priority process needs it. The DMC reporting cannot discern how much memory is loosely locked up in this way.

In the Median CPU Usage panel, 100% means the entire system, however many cores the system has. This is in contrast to the Search Activity dashboards, where 100% means one core.

The disk space in this view refers only to partitions with a Splunk Enterprise instance on them.

What to look out for in this view

For long-running processes, a worrying thing to look out for is memory usage continuously increasing over time.
