Cluster actions

Elena Dvoryadkina

This article describes actions available for working with an ADQM Control cluster in the ADCM interface.

Overview

You can find cluster actions on the Clusters page.

The Clusters page
The Clusters page

The Clusters page displays a table with the following columns:

  • Name — name specified during the cluster creation.

  • State — the current state of the cluster (created, installed).

  • Product — product name.

  • Version — version of a bundle used to install the cluster.

  • Description — description specified during the cluster creation.

  • Concerns. The icon concern red dark concern red light indicates if there are critical errors in the cluster configuration or some job is running. When you hover over it, a pop-up window appears showing a description with a link that you can follow to perform the required configuration or get details. If the cluster is configured correctly and there are no currently running actions, the column is empty.

  • Actions. The column shows icons for managing a cluster:

    • actions default dark actions default light — opens a drop-down list that offers actions to manage the cluster.

    • upgrade default — indicates whether a new version of a bundle is available and allows you to upgrade the cluster version.

    • delete default — deletes information about the cluster from ADCM (it does not remove ADQM Control or make any changes to hosts that belong to the cluster).

You can click the icons described above to perform the corresponding cluster actions. When an action starts, ADCM displays the process and result of its execution on the Jobs page. From this page, you can navigate to a page with details on an individual job (by clicking a job name) to see inner steps of that job execution and analyze errors if they occur.

When you choose an action, ADCM displays a dialog window where you can run an action using the non-blocking mode (the Raising concerns step) and then confirm the launch of the action (the Confirmation step). On the Confirmation step, you can select the Verbose checkbox to see additional execution details on the Jobs page.

A set of available actions depends on the cluster state:

  • For a new cluster (the cluster state is created), an available action is:

    • Install — installs all cluster services.

  • After a cluster is installed (the cluster state is installed), the following actions are available:

    • Check — checks if all components of the installed cluster work correctly.

    • Manage SSL — allows you to configure and enable/disable SSL encryption for services of the ADQM Control cluster.

    • Reinstall status-checker — reconfigures and restarts the status checker for all cluster services. Use this action when migrating a cluster to a new ADCM server.

    • Start — starts all services of the cluster.

    • Stop — stops all services of the cluster.
