Service actions
ADCM UI provides actions to manage ADQM services. These actions are available on the Services tab. To open this tab, click an ADQM cluster name on the Clusters page and switch to the Services tab.
Refer to ADCM documentation for an overview of the Services tab and common actions. A set of actions available for working with a service of an ADQM cluster depends on the service type.
Actions available for all services of ADQM:
-
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.
ADQMDB
The component-host mapping interface for the ADQMDB service -
Check — checks whether the settings of hosts, components, and related services match the requirements of a service, and whether the service itself works correctly.
-
Start — starts a service.
-
Stop — stops a service.
Service-specific actions:
-
Reconfig (ADQMDB, Clickhouse Keeper, Chproxy) — updates a service configuration according to settings specified on the service configuration page.
ADQMDBWhen you start the Reconfig action for the ADQMDB service, Wizard opens, allowing you to configure the action. The following parameters are available in the first configuration step:
-
ADQMDB Hosts — hosts where the ADQMDB service configuration should be updated (use Add property to add a host).
-
Disable validation — turns on/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).
-
Restart — specifies whether the service should be restarted (applying changes to some parameters does not require restarting the service — in this case, it is enough to reload the configuration).
