Monitoring grid tasks

You can monitor grid tasks to ensure that a maintenance procedure is completing successfully.

For example, when you add grid nodes or a new data center site in an expansion, you can monitor the expansion grid tasks.

To view the status of grid tasks, select Grid > primary Admin Node > CMN > Grid Tasks > Overview > Main.

Each grid task goes through three phases:

Pending: The grid task has been submitted, but not started yet.
Active: The grid task has been started.
An active grid task can be either actively running or temporarily paused. If a grid task's status changes to Error, the task is continuously retried until it completes or it is aborted.

Grid tasks might report an error when a grid node becomes unavailable (lost connection or crash) or when another grid task is running. When the issue causing the error is resolved, grid tasks with a status of Error automatically start running again.
Historical: The grid task has been submitted, but is no longer active.
The Historical phase includes grid tasks that completed successfully, have been canceled or aborted, or have failed.
