I have clusters where the health is degraded by indices in read only state. Clicking through to the individual deployment UI for those clusters, the health is often not reportedly the same state.
Within ECE deployments top level page and within specific deployment UIs separately, the health is consistent, so I don't think the status is fluctuating. ECE top page seems to have a snapshot from some time in the past that bears little relation to the current status in Kibana.
Clicking through to Kibana, one cluster that is Unhealthy at the top level and is Healthy at the individual level, has lifecycle errors against several indices.
As context, the readonly state was probably induced by running out of storage. This has been addressed by deleting excessive uncompressed log files. The cluster in question has had:
to clear the readonly status. I believe there are no longer readonly indices on this cluster.
What is going on with cluster health reporting?
