In this hands-on lab, you will be using `Performance Co-Pilot` (`pcp`) to monitor a lab system. As part of the lab, you will install `pcp` with some additional packages. You will configure `pmlogger` to ensure logging is configured correctly, then use the `pcp atop` command view system utilization and process activity. Finally, `pminfo` and `pmdumptext` to view system system metrics.
