Build it by describing it

Type a sentence like this and the copilot builds, validates and simulates the workflow.
When “New Firing Alert” happens in Prometheus Alertmanager, check the details with AI, then “List Alerts” and tell my team in Slack.
  • Simulated before it goes live
  • Fixes proposed when something breaks
  • One credit per run

Triggers

Start a workflow when this happens
  • WHEN
    New Firing Alert

    Triggers when an alert starts firing in Alertmanager. Each alert triggers once per firing, even if Prometheus keeps re-sending it.

Actions

Then Calibra can do this for you
  • DO
    List Alerts

    Lists the alerts Alertmanager currently knows about, filtered by labels and by whether they are silenced or inhibited.

  • DO
    Send Alert

    Sends an alert to Alertmanager so it is grouped, routed and notified like any Prometheus alert. Send it again with an end time to resolve it.

  • DO
    List Silences

    Lists the silences in Alertmanager, optionally only active, pending or expired ones, or those with certain matchers.

  • DO
    Create Silence

    Mutes notifications for alerts that match some labels, for a set time (for example, during planned maintenance).

  • DO
    Expire Silence (end it now)

    Ends a silence immediately, so the alerts it muted start notifying again. The silence stays in Alertmanager as expired.

  • DO
    Custom Alertmanager API Request

    Makes a request to any endpoint of the Alertmanager API v2, for example /alerts/groups or /receivers. Your credentials are added automatically and are only sent to your Alertmanager URL.
