can't get critical alerts from a dashboard

Question

Hello!I'm using CM api v19I'm trying to get only critical alerts which I'm looking at right now (RED ones).Tried https://cloudera.github.io/cm_api/apidocs/v19/path__events.html  /api/v19/events?query=category==HEALTH_EVENT;severity=CRITICAL   The output consists of too many not relevant events. What should I do to get only critical events displayed on the dashboard?Thank you.

Hi, @hamsterrrrr ,

Those events represent the point-in-time occurrence when the alert was thrown. They don't tell you the current issues with the cluster, which is what you see in the UI.

I don't think the REST API has an endpoint that gives you that list directly, but it's pretty easy to find out.

In the results of the /clusters/{cluster}/services endpoint, look for services with the status = BAD or health checks with summary = BAD. For example:

{
  "items": [
    {
      "name": "impala",
      "type": "IMPALA",
      "healthSummary": "BAD",                 <<--- this
      "healthChecks": [
        ...
        {
          "name": "IMPALA_IMPALADS_HEALTHY",
          "summary": "BAD",                   <<--- or this
          "suppressed": false
        },
        ...
      ],
      ...
    }
  ]
}

Cheers,

André
