Chapter 14. Using the system health dashboard
The Red Hat Advanced Cluster Security for Kubernetes system health dashboard provides a single interface for viewing health related information about Red Hat Advanced Cluster Security for Kubernetes components.
The system health dashboard is only available on Red Hat Advanced Cluster Security for Kubernetes 3.0.53 and newer.
14.1. System health dashboard details
To access the health dashboard:
-
On the RHACS portal, navigate to Platform Configuration
System Health.
The health dashboard organizes information in the following groups:
- Cluster Health - Shows the overall state of Red Hat Advanced Cluster Security for Kubernetes cluster.
- Vulnerability Definitions - Shows the last update time of vulnerability definitions.
- Image Integrations - Shows the health of all registries that you have integrated.
- Notifier Integrations - Shows the health of any notifiers (Slack, email, Jira, or other similar integrations) that you have integrated.
- Backup Integrations - Shows the health of any backup providers that you have integrated.
The dashboard lists the following states for different components:
- Healthy - The component is functional.
- Degraded - The component is partially unhealthy. This state means the cluster is functional, but some components are unhealthy and require attention.
- Unhealthy - This component is not healthy and requires immediate attention.
- Uninitialized - The component has not yet reported back to Central to have its health assessed. An uninitialized state may sometimes require attention, but often components report back the health status after a few minutes or when the integration is used.
Cluster health section
The Cluster Overview shows information about your Red Hat Advanced Cluster Security for Kubernetes cluster health. It reports the health information about the following:
- Collector Status - It shows whether the Collector pod that Red Hat Advanced Cluster Security for Kubernetes uses is reporting healthy.
- Sensor Status - It shows whether the Sensor pod that Red Hat Advanced Cluster Security for Kubernetes uses is reporting healthy.
- Sensor Upgrade - It shows whether the Sensor is running the correct version when compared with Central.
- Credential Expiration - It shows if the credentials for Red Hat Advanced Cluster Security for Kubernetes are nearing expiration.
Clusters in the Uninitialized state are not reported in the number of clusters secured by Red Hat Advanced Cluster Security for Kubernetes until they check in.
Vulnerabilities definition section
The Vulnerabilities Definition section shows the last time vulnerability definitions were updated and if the definitions are up to date.
Integrations section
There are 3 integration sections Image Integrations, Notifier Integrations, and Backup Integrations. Similar to the Cluster Health section, these sections list the number of unhealthy integrations if they exist. Otherwise, all integrations report as healthy.
The Integrations section lists the healthy integrations as 0 if any of the following conditions are met:
- You have not integrated Red Hat Advanced Cluster Security for Kubernetes with any third-party tools.
- You have integrated with some tools, but disabled the integrations, or have not set up any policy violations.
