About this Hands-on Lab

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.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

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
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.
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.

Additional Resources

SCENARIO:

You are a Linux System Administrator working for a software development company. You have been working with the software validation team to provide a new environment where they can test and troubleshoot software releases. The team has requested additional monitoring and logging tools, specifically Performance Co-Pilot. Leadership has assigned you the task, so you will need to install Performance Co-Pilot along with a couple of additional packages, configure the logging service, and test a couple of the utilities before returning the system to the validation team.
