To get Prometheus alerts on your phone, add a webhook receiver in Alertmanager that points at your Hook.Notifier URL, then route alerts to it. A firing alert arrives on your phone as a native push notification.
Alertmanager does the hard part: grouping, de-duplicating, silencing and routing. What it does not include is a native phone push. Hook.Notifier is a free receiver for that.
Add a webhook receiver
In your alertmanager.yml, define a receiver and route to it:
receivers:
- name: hooknotifier
webhook_configs:
- url: "https://hooknotifier.com/{IDENTIFIER}/{KEY}?object=Alert%20firing&body=A%20Prometheus%20alert%20is%20active&tags=monitoring&priority=high"
send_resolved: true
route:
receiver: hooknotifier
Reload Alertmanager to apply it. Firing alerts now reach your phone, and with send_resolved: true you also get the recovery.
First get your URL
Your Hook.Notifier URL is https://hooknotifier.com/{IDENTIFIER}/{KEY}. Create a free account to get yours, then paste it into the webhook receiver.
Route by severity
Alertmanager routing is the whole point. Send warnings and critical pages to different Hook.Notifier URLs with different priorities:
route:
receiver: warnings
routes:
- matchers: [ severity="critical" ]
receiver: critical
receivers:
- name: warnings
webhook_configs:
- url: "https://hooknotifier.com/{IDENTIFIER}/{KEY}?object=Warning&body=A%20warning%20is%20firing&tags=warning&priority=normal"
- name: critical
webhook_configs:
- url: "https://hooknotifier.com/{IDENTIFIER}/{KEY}?object=CRITICAL&body=A%20critical%20alert%20is%20firing&tags=incident&priority=critical&color=%23EE6767"
A warning waits for your quiet hours; a critical page cuts through them. Both land in a tagged inbox you can search later.
Why it matters
You already invested in Prometheus and Alertmanager to know exactly when something is wrong. The last step is a delivery channel that reaches your pocket without a paid integration or another push server to run. One webhook receiver closes it, for free.
