Activity Center

Active / Alert / History tabs

Activity Center is organized into three tabs. Each tab corresponds to a specific stage of the operation lifecycle. Counters in tab headers update in real time via SSE.

Active — active operations

The Active tab contains operations that are running right now or waiting in queue.

What is displayed

  • In Progress — operations actively running on devices. A progress bar shows the completion percentage
  • Pending — operations that are queued and waiting to execute

What you can do

  • Expand an operation to view detailed progress for each device
  • Delete an operation in Pending status (not yet started)

Operations in In Progress status cannot be canceled — they run to completion.


Alert — requires attention

The Alert tab contains operations that completed with errors and are awaiting operator confirmation.

An operation enters Alert if its status is Partial or Failed — meaning some or most devices completed the operation with errors.

Why Alert exists

Alert serves as a checkpoint — the operator sees problematic operations, investigates them, takes action (e.g., retries the operation only on failed devices), and confirms that the issue has been handled.

Confirmation (Accept)

After reviewing errors, click Accept on the operation — it will move to the History tab, retaining its original status and color. You cannot delete an operation from Alert — only through Accept.

Quick error handling

Click Isolate failed in the operation card — the Workers list will open with a filter showing only devices where the operation failed. This allows you to immediately retry the operation on just those devices.


History — operation history

The History tab contains the archive of all completed operations: successful, accepted from Alert, and deleted from Active.

What is displayed

  • All operations with their final status (Success / Partial / Failed)
  • Start time and duration
  • Brief statistics: how many devices completed successfully, how many with errors

Managing history

  • Operations can be deleted from History to clean up the log
  • Filter by operation type and time period — for quick search in a large archive
