Alert suppression lets you temporarily or permanently hide specific alerts 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 can be applied at three levels:
| Level | Scope | Use Case |
|---|---|---|
| Individual Alert | Suppresses a single specific alert instance | One-off known issue on a particular device |
| Category | Suppresses all alerts of a specific category (e.g., Device Set Health, Gateway Connection, CPU, Memory) | Planned maintenance affecting an entire alert category |
| Per-Room | Suppresses alerts for a specific room | Room undergoing renovation or hardware replacement |
Suppressing an Alert
- Open the Hotlist in Innomesh Portal.
- Locate the alert you want to suppress in the Active tab.
- Right-click the alert (or use the context menu) and select Suppress.
- Choose a suppression duration:
- Timed: Set a specific duration (e.g., 1 hour, 24 hours, 7 days)
- Indefinite: Suppress permanently until manually lifted
- Optionally add a reason for the suppression (recommended for audit purposes).
- Click Confirm.
The alert moves to the Suppressed tab immediately.
Category-Specific Suppression
Rather than suppressing alerts one by one, you can suppress an entire alert category for a room or across the environment. Available categories include:
- Device Set Health
- Gateway Connection
- CPU Utilisation
- Memory Utilisation
- Temperature
- Reachability
To apply category suppression, use the Suppress by Category option from the Hotlist toolbar or from the room’s context menu in the Rooms page.
Managing Suppressed Alerts
View all suppressed alerts in the Suppressed tab of the Hotlist. From this tab you can:
- Lift suppression: Return the alert to the Active tab
- Extend suppression: Add more time to a timed suppression
- View suppression reason: See why the alert was suppressed and by whom
