Chapter 2. Installing insights-client

Use these instructions to deploy the Red Hat Lightspeed client (insights-client) on an existing, cloud marketplace-purchased Red Hat Enterprise Linux system managed by Red Hat Update Infrastructure (RHUI).

The Red Hat Lightspeed client runs automatically, according to its scheduler settings. By default, it runs every 24 hours. To run the client interactively, enter the insights-client command.

When you run insights-client, the following values and settings determine the results:

The Red Hat Lightspeed client is not automatically installed on systems running the minimal installation of Red Hat Enterprise Linux 8.

For more information about minimal installations, see Customizing the system in the installer and Interactively installing RHEL from installation media.

If you do not select the Standard checkbox, RHEL installs without the insights-client package. If that happens, you can use dnf install to install the Red Hat Lightspeed client at a later time.

You will see the client and core versions.

Client: 3.10.1
Core: 3.6.3

Client: 3.10.1
Core: 3.6.3

The Red Hat Lightspeed client (insights-client) executes a number of commands that collect data on your system. Therefore, it has a configuration restriction that limits its CPU usage to no more than 30%. This restriction is defined in the configuration file:

This configuration prevents the Red Hat Lightspeed client from creating a CPU spike on your system. This spike could interfere with other applications running on your system. Specifically, it could prevent applications that depend on real-time scheduling from initiating.

If you need to enable real-time scheduling, you can disable the CPU quota restriction. The risk of removing this configuration is minimal. However, it is possible that when the Red Hat Lightspeed client runs, the CPU usage may become unusually high. If this situation occurs and negatively impacts other services on your system, please contact Red Hat support for assistance.
