Alerts and notifications
Thresholds, push, email, NOC mailboxes.
What triggers an alert
| Alert | When | Severity |
|---|---|---|
| High temperature | Above the PoP's warning level (default 26 °C) for 2 readings in a row | Warning |
| Critical temperature | At or above the critical level (default 30 °C) for 2 readings; the same alert escalates | Critical |
| Device offline | No data for 3 minutes (adjustable 2–15). Cause unknown: network, device or power | Critical |
| Sensor fault | The device is online but its sensor gives no valid readings | Warning |
| Mains failure | Mains absent, UPS supplying the load (needs power sensing installed) | Warning |
| UPS output failure / power unavailable | UPS output absent (needs power sensing installed) | Critical |
Alerts clear automatically: temperature when it falls below the warning level minus a 1 °C margin (hysteresis) for 2 readings, and offline alerts when data arrives again. Everyone notified gets a "Resolved" message.
Acknowledge and resolve
- Acknowledge tells the team someone is on it and stops the 30-minute reminders.
- Resolve closes the alert with a note. If the problem is still there, it reopens after 2 more readings.
- Technicians and above can acknowledge and resolve.
Where alerts are sent
| Channel | Default | Set up |
|---|---|---|
| In-app inbox | Everyone, all alerts | Nothing to do |
| Push (phone/desktop) | Warning and above | Notifications → Enable on this device, on each phone |
| Owners, admins, network ops; warning and above | Notifications → Your notifications | |
| Alert contacts | Per contact | Notifications → Alert contacts (e.g. your NOC mailbox) |
Each person chooses their own channels and minimum severity under Notifications.
Thresholds per PoP
Under PoPs & devices → Edit alert thresholds (Network Operations and above): warning, critical, hysteresis and how long without data counts as offline.
Maintenance
During a planned maintenance window, alerts are still recorded but nobody is notified.
Push on iPhone
iOS only delivers web notifications to installed apps: in Safari tap Share → Add to Home Screen, open PoPLense from the Home Screen, then enable notifications.
