Restart

Lisa Vaysman

The Restart action stops and then starts all services of the cluster.

To run an action, go to Clusters page, click actions default dark actions default light in the Actions column, and select the action from the drop-down list that appears.

The dialog window of the Restart action contains the Apply configs from ADCM setting. If the value true is selected, then the services are launched taking into account all the parameters specified in the settings of these services in ADCM. Otherwise, the settings of these services in ADCM are ignored. Next, confirm the action by clicking Next and Run.

You can find execution process and result of the action on the Jobs page. On this page, you can view action execution details, including verbose Ansible STDOUT/STDERR outputs.

The Restart cluster action automatically restarts all cluster services and their components in the optimal logical order.

During restart, the cluster services are unavailable. If the VictoriaMetrics Storage component contains a large volume of data, the cluster restart process may take long time to complete (see the VictoriaMetrics documentation).

Alternatively, you can use the Restart action of a particular service or its component to manually restart only required services or components one after another.

NOTE

  • Grafana can be restarted at any moment independently of VictoriaMetrics. Once the VictoriaMetrics Select component is up and running, Grafana automatically connects to it to fetch metrics for display. The VictoriaMetrics Select component, subsequently, retrieves data from the VictoriaMetrics Storage component as soon as this component becomes operational.

  • If both Grafana and VictoriaMetrics have been running and then VictoriaMetrics is restarted, then it is not necessary to restart Grafana (Grafana reconnects to VictoriaMetrics automatically).
