Chapter 21. Optimizing the system performance in the web console

You can set a performance profile in the RHEL web console to optimize the performance of the system for a selected task.

Red Hat Enterprise Linux provides several performance profiles that optimize the system for:

  • Systems using the desktop
  • Throughput performance
  • Latency performance
  • Network performance
  • Low-power consumption
  • Virtual machines

The TuneD service optimizes system options to match the selected profile. In the web console, you can set your system’s performance profile.

Depending on the task you want to perform, use the web console to optimize system performance by setting a suitable profile.

Prerequisites

Procedure

  1. Log in to the RHEL 10 web console.
  2. Click Overview.

  3. In the Configuration section, click the current performance profile.

    Performance profile in the Overview pane of the web console

  4. In the Change performance profile dialog box, set the required profile.
  5. Click Change profile.

The RHEL web console uses the Utilization Saturation and Errors (USE) Method for troubleshooting. The new performance metrics page has a historical view of your data organized chronologically with the newest data at the top. In the Metrics and history page, you can view events, errors, and graphical representation for resource utilization and saturation.

Prerequisites

  • You have installed the RHEL 10 web console.

    For instructions, see Installing and enabling the web console.

  • The cockpit-pcp package is installed.

    The Metrics and history section opens and displays: the current system configuration and usage the performance metrics in a graphical form over a user-specified time interval

Grafana aggregates data from multiple systems to visualize their Performance Co-Pilot (PCP) metrics graphically. You can configure performance metrics monitoring and export for several systems in the web console interface.

Prerequisites

  • You have installed the RHEL 10 web console.

    For instructions, see Installing and enabling the web console.
