Feature: additional actions/links to be renderd in sink Findings

[Dariusch]

Is your feature request related to a problem?

Most of our alerts are enriched with additional annotations like dashboard_url and runbook_url to make debugging and resolving issues faster. Not everything can be automated, sadly...
Those annotations were previously used to render slack actions/links to the specified hyperlinks.

Describe the solution you'd like

Passing additional (external) links to the (slack_)sink configs which are then rendered when present on the alert.

Describe alternatives you've considered

Currently, only robusta-provided links to the UI are configured: https://github.com/robusta-dev/robusta/blob/master/src/robusta/integrations/slack/sender.py#L282-L303

Additional context

The example I am talking about is described here.

Thanks for reporting it @Dariusch

How would you configure those links?
Does all alerts has those links? (dashboard_url, runbook_url)
Would you want to configure it per alert?
Or, it's something that converts given annotations to buttons, if those are available?

Not all of the alerts have those links.

Yes

For example the PrometheusRules configured by the kube-prometheus-stack do not have those annotations.

A flux alert could link to a dashboard for example:

---
apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  name: flux-rules
  namespace: monitoring
spec:
  groups:
    - name: flux
      rules:
        - alert: ReconciliationFailure
          expr: max(gotk_reconcile_condition{status="False",type="Ready"}) by (exported_namespace, name, kind) + on(exported_namespace, name, kind) (max(gotk_reconcile_condition{status="Deleted"}) by (exported_namespace, name, kind)) * 2 == 1
          for: 3m
          labels:
            severity: warning
            team: engineering
          annotations:
            summary: '{{ $labels.kind }} {{ $labels.exported_namespace }}/{{ $labels.name }} reconciliation failed'
            description: '{{ $labels.kind }} {{ $labels.exported_namespace }}/{{ $labels.name }} reconciliation failed for more than 10 minutes'
            dashboard_url: https://grafana.${domain}/d/flux-cluster/flux-cluster-stats?orgId=1&refresh=30s

Or add the runbook URL.
Annotation and labels are a kv map.

I guess a proposed solution would be to add a list to the slack sink config which is mutated into the slack schema like

- slack_sink:
    # Other values
    actions:
      - type: button
        text: 'Runbook :green_book:'
        url: '{{ (index .Alerts 0).Annotations.runbook_url }}'

FYI, we made some improvements around including links in Slack messages here: #967

It doesn't handle existing links from annotations/labels on the alert. But we're thinking about expanding this to your use case, as well as showing links from annotations in the Robusta UI.
