Red Hat Summit15.2. Collecting data for Red Hat Support
When you submit a support case to Red Hat Support, it is helpful to provide debugging information for OpenShift Container Platform and OpenShift Virtualization by using the following tools:
- must-gather tool
-
The
must-gathertool collects diagnostic information, including resource definitions and service logs. - Prometheus
- Prometheus is a time-series database and a rule evaluation engine for metrics. Prometheus sends alerts to Alertmanager for processing.
- Alertmanager
- The Alertmanager service handles alerts received from Prometheus. The Alertmanager is also responsible for sending the alerts to external notification systems.

Collecting data about your environment minimizes the time required to analyze and determine the root cause.
Prerequisites
- You have set the retention time for Prometheus metrics data to a minimum of seven days.
- You have configured the Alertmanager to capture relevant alerts and to send alert notifications to a dedicated mailbox so that they can be viewed and persisted outside the cluster.
- You have recorded the exact number of affected nodes and virtual machines.
Procedure
- Collect must-gather data for the cluster.
- Collect must-gather data for Red Hat OpenShift Data Foundation, if necessary.
- Collect must-gather data for OpenShift Virtualization.
- Collect Prometheus metrics for the cluster.
