QRadar: Monitor Hostcontext processes with wait_for_start.sh

Troubleshooting


Problem

How can you monitor or check the status of Hostcontext processes? This article defines and provides steps for running the wait_for_start.sh script.

Cause

The wait_for_start.sh is a script to monitor and display the status of the Hostcontext processes. When starting services, patching, and upgrades, this script shows whether a process is running or stopped. This script runs on managed hosts or a primary host of any High Availability (HA) appliance. This script cannot run on secondary HA appliances, even if the secondary system is set to the active host.
Notes:
  • Different sub-services of Hostcontext run on the various managed hosts in QRadar.
  • By default, this script refreshes every 10 seconds.
  • By default, this script stops after 20 minutes whether or not all processes are running.
  • The script ends once all processes are in the running status.
