Alert suppression lets you temporarily or permanently hide alerts for a room or device from the active Hotlist without resolving the underlying condition. This is useful during planned maintenance, known-issue periods, or when a device consistently generates non-actionable alerts. Suppression rules were enhanced in Innomesh v3.5.2 with indefinite suppression and category-specific controls, and further refined in v3.5.3.
How Suppression Works
A suppressed alert moves from the Active tab to the Suppressed tab in the Hotlist. It remains tracked by the system; it is not resolved or deleted. When the suppression period expires (or is manually lifted), the alert returns to the Active tab if the condition persists.
Suppression is always targeted at a room or a device, never at an individual alert:
| Level | Scope | Example categories |
|---|---|---|
| Room | Suppresses all alerts for the room, or only a specific room alert category | Room Health, Room CPU, Room Memory, User Interface Unhealthy |
| Device | Suppresses alerts for a specific device in a room, optionally restricted to an asset alert category | Endpoint Communication, Endpoint Temperature, Peripheral Health |
Suppressing an Alert
- Open the Hotlist in Innomesh Portal.
- Open the alert you want to suppress in the Active tab.
- Click the Suppress Alert button on the alert’s action menu across the bottom left. This opens the Suppress Alerts Rule window. For a room-related alert, the room’s information is prepopulated in the window; for an asset-related alert, the asset’s information is prepopulated.
- Choose a suppression duration:
- Timed: Set a specific duration (e.g., 1 hour, 24 hours, 7 days)
- Indefinite: Suppress permanently until manually lifted
- Add a comment or reason for the suppression (required for notification and audit purposes).
- Click Add Rule.
The alert moves to the Suppressed tab over the course of a few minutes.
Managing Suppressed Alert Rules
Suppression rules are managed by clicking Alert Suppression Rules, which opens the Alert Suppression Rules window. From there you can:
- Lift suppression: Returns all alerts affected by that rule to the Active tab. Note that this happens over the course of a few minutes, not immediately.
- Extend the suppression: Adjust the suppression rule time period. You can also change the suppression rule to Suppress indefinitely.
- View suppression reason: See why an alert suppression rule was put in place, and by who.
