[Agent Health Dashboards] Zero Integrations Enabled

[jamiehynds]

A bug has been identified, whereby the Overview page on the agent health dashboards is incorrectly reporting 0 integrations enabled, even if several integrations are enabled and ingesting data. Need to determine the root cause and update the dashboard to ensure the integrations enabled count is accurate.

I took a look, and it appears this visualization started only reporting zero in 8.9.

I noticed differences in running a cardinality agg in 8.8.2 vs 8.10.1. When I dug in a bit more, it seemed specific to constant_keyword fields. Note the aggregations.0.value of 0 on 8.10.1:

8.8.2

  "aggs": {
    "0": {
      "cardinality": {

      }
    }
  },
  "size": 0
}

    },

  },
  "aggregations": {
    "0": {
      "value": 15 <= expected
    }
  }
}

8.10.1

      "cardinality": {

Unrelated observation: does the value for Integrations Enabled need the decimal?

[ebeahan]

Opened ES issue with above finding: elastic/elasticsearch#99776

Thanks for taking a look @ebeahan. With regards to the decimals, this is a known bug which @P1llus has raised with Kibana and they are working on a fix.

[ebeahan]

ES team added a fix for the cardinality agg issue: elastic/elasticsearch#99814. The fix ships in 8.10.3 and 8.11.0.

[jamiehynds]

Closing as a fix has been available since 8.10.3.
