Mobile alerting with tracking & escalation for Prometheus Alertmanager



When critical systems fail, SIGNL4 is the fastest way to alert your staff, engineers, IT admins on call and “in the field”. SIGNL4 provides reliable notifications via mobile app push, text and voice calls with tracking, escalations and duty scheduling.

Prometheus is an open-source monitoring tool that monitors availability and performance. It gives you simple access to relevant data for example using Grafana. SIGNL4 easily enables Prometheus to notify mobile teams in the field or on call in real-time. This speeds up their response significantly and frees resources in the operations.

Pairing Prometheus Alertmanager with SIGNL4 can enhance your daily operations with an extension to your team wherever it is. The integration does not only allow you to know when a critical issue has occurred but also when it was resolved no matter where you are.

 How it Works

Prometheus compatibility allows you to distribute operational alerts to a mobile SIGNL4 team by using a ready-made plugin. Persistent notifications and acknowledgement requirements ensure that issues will be handled before it is too late.

A sample configuration in the configuration file might look like this:

- name: prometheus-signl4
  - url:
    send_resolved: true
  - job
  group_interval: 5m
  group_wait: 30s
  receiver: prometheus-signl4
  repeat_interval: 10m
  - match:
      alertname: Watchdog
    receiver: prometheus-signl4

You need to replace with your SIGNL4 team secret.

Resolved Alerts

In order to close alerts in SIGNL4 when the alerts are closed in Prometheus you can use this SIGNL4 URL.

Test it

That is it and now you can test the alert. You can for example simulate an alert in Prometheus and you should then receive an alert in your SIGNL4 app.

SIGNL4 can further increase the visibility of alerts through its Signals and Services section. Augmenting the color and icon of alerts will provide more relevant information at a glance without having to open the alert.


Change alert color and override title + text 

Override text, colors and titles are triggered by keywords set within the mobile app.
