This reference covers the full catalogue of alerts that appear in the Innomesh Portal Hotlist. Each alert type is documented with its trigger conditions, severity level, grace period behaviour, and the subscription tiers to which it applies.
Alert Severity Levels
Alerts are classified into five severity levels:
| Severity | Description |
|---|---|
| Critical | Immediate attention required; service is impaired |
| High | Significant issue that may impact service |
| Medium | Notable condition that warrants investigation |
| Low | Minor issue or informational warning |
| Notice | Informational event with no service impact |
Alert Categories
Innomesh Environment and Edge Compute Host Alerts
These alerts monitor the health of the Innomesh servers and edge compute hosts that power your environment.
📝 Note
Host CPU alerts use a 2-minute threshold window to prevent one-off spikes from triggering critical alerts.
| Alert | Trigger | Tier | Severity | Grace Period |
|---|---|---|---|---|
| Host Storage | Edge compute server’s local disk usage exceeds 80% | Space VC, Space CE | Medium | Yes |
| Host Storage | Edge compute server’s local disk usage exceeds 90% | Space VC, Space CE | Critical | Yes |
| Host Memory | Edge compute server’s memory usage exceeds 80% | Space VC, Space CE | Medium | Yes |
| Host Memory | Edge compute server’s memory usage exceeds 90% | Space VC, Space CE | Critical | Yes |
| Host CPU | Edge compute server’s CPU usage exceeds 80% (sustained 2 minutes) | Space VC, Space CE | Medium | Yes |
| Host CPU | Edge compute server’s CPU usage exceeds 90% (sustained 2 minutes) | Space VC, Space CE | Critical | Yes |
| Host Health | Edge compute server fails to respond to 3 consecutive service-status pings | Space VC, Space CE | Critical | No |
| Licensing | Number of rooms exceeds the subscribed Innomesh room licence count | All | Critical | Yes |
| Alert Influx | High influx of Low, Medium, or High severity alerts detected | All | Critical | No |
📝 Note
In a high-availability (HA) setup, Host Health triggers an automatic host rotation and the issue self-resolves.

Projector Lamp Life Thresholds
Lamp hour alerts trigger when a projector’s lamp usage reaches the manufacturer-recommended replacement threshold. If a specific model is not listed, Innomesh falls back to the manufacturer’s DEFAULT value below. If the projector is not covered by any manufacturer, it defaults to 1,500 hours.

Thresholds can be customised per device if the default does not match your maintenance schedule.
Device Endpoint Temperature Thresholds
Temperature alerts fire when a device exceeds its maximum operating temperature. The default threshold is 40 degrees Celsius unless a device-specific override is defined.
| Brand | Model | Threshold (C) |
|---|---|---|
| AMX | DGX | 60 |
| AMX | DVX | 55 |
| Extron | IN-1608 | 60 |
| Extron | Crosspoint DTP | 65 |
| Panasonic | Default | 60 |
| Panasonic | RZ470 | 68 |
| Panasonic | RZ570 | 75 |
Grace Periods
Many alerts include a grace period during which the condition must persist before the alert is published to the Hotlist. This prevents transient events from generating unnecessary noise. Grace period durations are indicated in the alert catalogue for each alert type.
