Upgrade of Cloud Native Cluster Monitoring
Check Items
During a cluster upgrade, compatibility issues occur when the Cloud Native Cluster Monitoring add-on is upgraded from a version earlier than 3.9.0 to a version later than 3.9.0. Check whether Grafana is enabled for this add-on.
Solution
In versions later than 3.9.0, Cloud Native Cluster Monitoring is not built in with Grafana capabilities anymore. Therefore, reinstall an open-source Grafana version before upgrading Cloud Native Cluster Monitoring.
- Reinstalling Grafana does not affect existing data.
- Manually created Grafana Services and ingresses cannot be directly associate with the newly installed Grafana. To resolve this issue, manually change the selector for the affected Services and ingresses.
Solution 1: If Cloud Native Cluster Monitoring can be upgraded to 3.9.0 or later, upgrade it on the Add-ons page. In the displayed dialog box, click Install Grafana. After the request is submitted, continue to upgrade the add-on to the latest version.
Solution 2: If Cloud Native Cluster Monitoring cannot be upgraded to 3.9.0 or later, perform the following operations to manually migrate Grafana:
- Disable Grafana on Cloud Native Cluster Monitoring.
Go to the add-on list, click Edit of Cloud Native Cluster Monitoring. On the Edit Add-on page, disable Grafana.
- Install open-source Grafana.
On the Add-ons page, install Grafana.
