# Google Cloud Monitoring to Pagerless

> Paste one URL into Google Cloud Monitoring. Pagerless decides who to wake, explains it in plain words and closes the problem when Google Cloud Monitoring says it's fixed.

## Set up

Your URL is in the Pagerless app under Other tools, with the key filled in:

```text
https://events.pagerless.dev/v1/hooks/gcp/<your ingest key>
```

1. **Open Monitoring, Notification channels** In Google Cloud Monitoring.
2. **Add a Webhook notification channel with your Pagerless URL, or a Pub/Sub push subscription to it.** 
3. **Attach the channel to your alerting policies.** 

## What happens

| When | Pagerless |
| --- | --- |
| Fires | Incident state open |
| Clears | Closed |
| How loud | The incident severity |
| Proof it's you | The key in the URL. A Pub/Sub push with an OIDC token is also verified against Google's certificates. |

## Choosing who gets woken

| Rule | Example |
| --- | --- |
| Name rules on the URL | `?wake=prod-*&log=*-staging` (globs, case-insensitive) |
| The tool's own severity | critical, p1, sev1, fatal wake; error, warning tell; info, low log |
| A default on the URL | `?level=wake` (or tell, log). Without one: tell. |

`?service=` and `?env=` set the service and environment shown on the problem.
