Both 'total' and 'quota' would be prohibitively expensive for the kind
of archives this module targets as it would require counting items
across the entire archive.

--- labels: - 'Stage-Alpha' summary: Alertmanager webhook receiver for pubsub --- # Introduction This module lets [Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/) publish alerts to [pubsub][doc:pubsub] via [webhooks](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config). # Setup The relevant pubsub nodes must be created and configured somehow. Because the request IP address is used to publish, the `publisher` affiliation should be given to the IP address Alertmanager sends webhooks from. # Configuration ## Prometheus A Prometheus `rule_files` might contain something along these lines: ``` yaml groups: - name: Stuff rules: - alert: Down expr: up == 0 for: 5m annotations: title: 'Stuff is down!' labels: severity: 'critical' ``` ## Alertmanager On the Alertmanager site the webhook configuration may look something like this: ``` yaml receivers: - name: pubsub webhook_configs: - url: http://pubsub.localhost:5280/pubsub_alertmanager ``` And then finally some Alertmanager routes would point at that receiver: ``` yaml route: receiver: pubsub ``` ## Prosody On the Prosody side, apart from creating and configuring the node(s) that will be used, configure your pubsub service like this: ``` lua Component "pubsub.example.com" "pubsub" modules_enabled = { "pubsub_alertmanager", } -- optional extra settings: alertmanager_body_template = [[ *ALARM!* {annotations.title?Alert} is {status} Since {startsAt}{endsAt& until {endsAt}} Labels: {labels% {idx}: {item}} Annotations: {annotations% {idx}: {item}} ]] alertmanager_node_template = "alerts/{alert.labels.severity}" ``` If no node template is given, either an optional part after "pubsub_alertmanager" in the HTTP path is used as node, or the string "alerts". Here, an alerts would be published to different nodes based on the 'severity' label, so e.g. `alerts/critical` in this example. ## All Options Available configuration options: `alertmanager_body_template` : Template for the textual representation of alerts. `alertmanager_node_template` : Template for the pubsub node name, defaults to `"{path?alerts}"`
