Running health checks

DrQ is an extensible health check framework for QRadar®. Run DrQ health checks before major events, such as upgrades, to determine whether there are any issues that need to be addressed first. You can also run DrQ routinely to monitor the health of your system. You can run all health checks at once, an individual check, or a group of checks.

About this task

DrQ is independent of each host and can be run only by the root user. When you run DrQ, it only has access to the files on the current host. It does not have the ability to communicate to any other host in the deployment. Each health check is designed to only run on the appropriate host.

Procedure

To run health checks, type the following command.

drq

This command runs all available checks in /opt/ibm/si/diagnostiq with the checkup mode, and with the summary output mode.

The following table shows the general parameters for DrQ.
