23 ## Prometheus
24
25 A Prometheus `rule_files` might contain something along these lines:
26
27 ``` yaml
28 groups:
29 - name: Stuff
30 rules:
31 - alert: Down
32 expr: up == 0
33 for: 5m
34 annotations:
35 title: 'Stuff is down!'
36 labels:
37 severity: 'critical'
38 ```
39
40 ## Alertmanager
41 On the Alertmanager site the webhook configuration may look something
42 like this:
43
44 ``` yaml
45 receivers:
46 - name: pubsub
47 webhook_configs:
48 - url: http://pubsub.localhost:5280/pubsub_alertmanager
49 ```
50
51 And then finally some Alertmanager routes would point at that receiver:
52
53 ``` yaml
54 route:
55 receiver: pubsub
56 ```
