Kibana status is Yellow - Plugins with degraded status

[andreluisdebiasi]

Kibana version: 7.17.4

Elasticsearch version: 7.17.4

Server OS version: Oracle Linux Server release 7.9 - 4.14.35-2047.513.2.3.el7uek.x86_64

Browser version: 103.0.5060.134

Browser OS version: Google Chrome

Original install method (e.g. download page, yum, from source, etc.): tar.gz

Describe the bug: In Stack Monitoring Kibana is showing the following messages: Some plugins may be experiencing issues. Please check the Kibana status page and Kibana status is Yellow with many plugins with degraded status. The environment is working fine, but I would like to resolve these yellow alerts.

Expected behavior: Kibana status green

Screenshots (if relevant):

Hi @andreluisdebiasi :wave: The cause for the degradation of the plugin status should be written to the Kibana log. Could you check whether there's anything to be found there?

[smith]

Is the issue that these plugins are in a green status but the UI is showing them as yellow? Or is it that they are yellow? I'm having trouble understanding if the Stack Monitoring UI is behaving as it should be based on this report.

[matthiasledergerber]

Same issue. Elastic-Stack 8.8.2. This issue exists since some versions. Three Kibana Nodes. All report the same issue. Not sure why this happens or if there is really an issue.

In the Kibana.log we do have some errors that come up from time to time.

Thanks for posting that @matthiasledergerber. Would you say the Stack Monitoring UI is behaving correctly here? The errors in the logs look like they're coming from a search exception in a background task.

The original issue description says, "The environment is working fine, but I would like to resolve these yellow alerts." Are these valid alerts?

If the Stack Monitoring UI is behaving as expected here, this issue should be closed. If not we should investigate further and make sure the alerts are displaying correctly.

[matthiasledergerber]

I cannot confirm or deny. How can I track down the search that is related to this issue? It seems like the error is cascading through all the other services. I question if this is intended because for the user it looks like Kibana is failing. Furthermore, the error is prominent in the Monitoring overview that something is wrong with Kibana.

[weltenwort]

The specific error message seems to come from the taskManager plugin. Maybe @elastic/response-ops can help with diagnosing the underlying reason?

[matthiasledergerber]

Issue still persists with Kibana 8.10.0
