When a value exceeds its limit, the system notifies immediately by push, email or webhook. Escalated by responsibility, so the message reaches the right person.

Alerting Monitoring

- **Trigger:** limit exceeded
- **Channels:** Push, email, webhook
- **Escalation:** by role and responsibility
- **In practice:** also phone call and SMS

## From limit to message

An alert is only useful if it reaches someone who can act.

- Limit detected: A measured value leaves its defined range, or a site goes offline.
- Notified immediately: By push, email or webhook to the responsible party, including your own systems.
- Escalated in stages: The alert goes to the person responsible according to their role.

## From practice: a phone call instead of an overlooked email

For the lighting monitoring of an outdoor advertising company in Berlin, we built the alerting ourselves, from the circuit board to the phone system.

- Phone call, SMS and email: The central server alerts the responsible person by phone call, SMS or email.
- Connected to the phone system: The server is connected to the client's phone system. A call is hard to miss, while an email easily gets lost in the on-call inbox.
- Escalation by situation: The escalation logic decides which channel is used, based on the time of day and the importance of the site.
- The box monitors itself: The firmware checks its own function and reports in regularly. That way even a silent failure is noticed.

## Who should know when something fails?

We define limits, channels and responsibilities with you and build the alerting to match.
