Maintaining KOF#

Backup Requirements#

Backing up KOF requires backing up the following:

  • Grafana configurations
  • Alert definitions
  • Custom dashboards
  • Retention policies

Grafana#

  • Effective immediately, Mirantis will no longer distribute Grafana as part of its products or services. This change is being made to proactively avoid potential licensing, redistribution, or compliance considerations related to third-party software. For more information, please contact Mirantis.
  • Review the Using KOF and Grafana in KOF guides in the latest Mirantis k0rdent Enterprise version for instruction on how to install Grafana and Mirantis-provided Grafana dashboards, and to optionally install and integrate with grafana-operator for Grafana lifecycle management.

Health Monitoring#

To implement health monitoring:

  1. Apply the steps in the Verification section
  2. Apply the steps in the Sveltos section
