Real-time updates

What updates in real time

• Operation progress — Pending / In Progress / Completed / Error counters in the operation card update as execution proceeds
• Header indicator — the color and Activity N / M counter update instantly when new operations or alerts appear
• Tab transitions — an operation automatically moves from Active to Alert or History without user intervention
• New operations — if a colleague starts an operation at the same time, it will appear in your Activity Center without refreshing the page

How SSE works

SSE is a persistent one-way connection between the browser and the server. The server sends events as they occur. Unlike WebSocket, it is a lighter protocol well-suited for notification streams.

Behavior on connection loss

If the connection to the server is interrupted (e.g., due to unstable internet), Activity Center:

1. Automatically attempts to reconnect
2. After the connection is restored — requests missed events
3. Updates the state of all operations to the current one

The user does not need to do anything manually — recovery happens transparently.

Connection indicator

When the SSE connection is lost, a notification about the connection issue appears in the interface. After recovery, the notification disappears automatically.
