Using Performance Co-Pilot to Collect and View System Performance Data

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. *This course is not approved or sponsored by Red Hat.*

Challenge

Install Packages and Start Services
1. Install the PCP, pcp-zerconf, and pcp-system-tools packages.
2. Enable and start the pmcd and pmlogger services.
  - Confirm both services are running as expected.
3. Configure pmlogger.
  - Run the pmlogconf utility.
  - Review the prompts and complete the configuration using a base configuration.
  - Once the configuration is complete, cycle the pmcd and pmlogger services.
4. Start local system services.
  - evotl
  - evodd
Challenge

Investigate System Utilization, Resources, and Processes
1. Use pcp atop command to view utilization details and processes.
  - Launch pcp atop.
  - Sort the view by memory usage and identify the process using the most memory.
  - Sort the view by CPU usage and identify the process using the most CPU time.
  - Monitor the CPU and memory metrics in the upper section of the output.
2. View available metrics using pminfo.
  - View the full list available metrics.
  - Filter list of available metrics and locate the following values:
    
    free and used memory
    
    free and used swap
  - Use pminfo to display point in values for the metrics identified above.
    
    Review the information provided and make note of the values.
3. Use pmdumptext display specific metrics.
  - Create a custom view on a 2-second refresh cycle, using the following metrics:
    
    kernel load
    
    memory used and free
    
    swap used and free
  - Review the information and make note of the values.
Challenge

Stop the Local Services and Monitor the System Again
1. Stop the evotl and evodd services.
2. Launch pcp atop.
  - Review the memory and CPU utilization data.
  - Confirm system utilization reduction with the services stopped.
3. Use pmdumptext to review the same metrics.
  - Confirm system utilization reduction with the services stopped.
