Stack Monitoring Not Stable

I've just upgraded our cluster from 7.6.2 to 7.7.1. I've a 10 Node cluster, self monitored with metricbeat + logstash and kibana monitoring using "Stack Monitoring" feature. It worked quite well with 7.6.2 but with 7.7.1 I can't see the logstash metrics anymore in the "Stack Monitoring" tab even though the data is shipped to our dedicated monitoring cluster.

After the upgrade I also had to reset to see the Kibana and Elasticsearch metrics again:

PUT _cluster/settings
  "persistent": {
    "xpack.monitoring.collection.enabled": true

It's annoying that one has do debug such things after just a minor upgrade with almost no informations in the logfiles.

Seem like Kibana knows that there is data, but it's not showing any nodes:

still the same issue with 7.8. Any hints?

Hi @tomx1,

Do you see any .monitoring-logstash-* indices on the monitoring cluster with recent dates? Do you Logstash monitoring data on the cluster overview page? Are you using Metricbeat to monitor Logstash?
