Real-time Updates
Activity Center uses Server-Sent Events (SSE) technology to deliver real-time updates — without the need to reload the page or make periodic requests to the server. v0.9.0
What is updated in real-time
- Operation progress — Pending / In Progress / Completed / Error counters in the operation card are updated as they execute
- 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 a page refresh
How SSE works
SSE is a persistent, unidirectional 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 upon connection loss
If the connection to the server is interrupted (e.g., due to unstable internet), Activity Center will:
- Automatically attempt to reconnect
- After the connection is restored — request missed events
- Update the status of all operations to the current state
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 restoration, the notification disappears automatically.
Diagnostic Reports
A diagnostic report is an archive containing detailed technical information about a device or agent. `v0.8.5` It is used for submission to HashCore technical support or for self-diagnosis of issues.
Profile Management
The profile management section allows you to change the main data of your HashCore Pulse account.
