Service actions

Elena Dvoryadkina

ADCM UI provides actions to manage ADQM services. These actions are available on the Services page. To open this page, click an ADQM cluster name on the Clusters page and switch to the Services tab.

The Services page contains a table with the following columns:

  • Name — service name.

  • Version — service version.

  • State — the current state of the service (for example, created or installed).

  • Concerns — displays the icon concern red dark concern red light if critical errors are detected in the service configuration (for example, mandatory components are not deployed on cluster hosts) or a job is running. When you hover over it, a pop-up window appears showing an error description with a link that you can follow to perform the required configuration.

  • Actions. When you click the icon actions default dark actions default light, the drop-down list offers actions to manage the service. A set of actions depends on the service type.

     
    Actions available for all services:

    • Install (if a service state is created) — installs a service.

    • Add/Remove components — opens the component-host mapping interface where you can add, remove, and redistribute service components.

    • Check — checks whether the settings of hosts, components, and related services match the requirements of a service, and whether the service itself works correctly.

    • Reconfig and restart — updates a service configuration according to settings specified on the service configuration page, and restarts the service.

      In the Run an action window that opens when you select the action for the ADQMDB service, you can activate the Disable validation option to switch off the validation of the service configuration (in some cases, the configuration can be considered incorrect — for example, if it deletes storage policies that are still in use).

      Monitoring

       
      In the Run an action window that opens when you select the action for the Monitoring service, the Grafana: apply password parameter specifies whether the Grafana administrator password should be reset using the value of the Grafana settings → Grafana administrator’s password parameter located on the Primary configuration tab of the Monitoring service configuration page.

    • Start — starts a service.

    • Stop — stops a service.

     
    Service-specific actions:

    • Manage auto core dump (ADQMDB) — enables/disables an automatic core dump.

    • Restart (ADQMDB, Clickhousekeeper, Chproxy) — stops and then starts a service.

    • Reinstall (Monitoring) — reinstalls a service.

     
    When an action starts, ADCM displays its execution process and result on the Jobs page. On this page, you can also analyze errors if they occur.

     
    The Actions column also displays separate icons for the following actions:

    • maintenance default — sets up the maintenance mode for a service. This functionality is currently not implemented in the ADQM bundle.

    • delete default — removes a service from the cluster.
