Kibana monitoring gaps when data node is replaced

Hi, I am using ES 7.2.0 on AWS spot instances. Cluster is comprised of 5 Master nodes, 8 Data nodes and 2 Coordinators. I noticed that whenever a data node is replaced (due to spot replacement), there are monitoring gaps in the whole cluster [25] During the gaps I tested GET .monitoring-es-7-/_search* and it returned valid information. The gap usually starts when the node goes up, until the EBS was warmed up and it's read latency is reduced (usually takes ~20-30 mins). Note that the cluste…

but I don`t know what should I do for my cluster. should I Post the same query DSL to cluster?

Can you share more info on your setup? Version, deployment, is it a fresh install or a upgrade ?

ES version:7.5.1
kibana version:7.4.2
I restarted after repairing the master node and found that the monitoring data was gone.
The operation steps are:
1.PUT /_cluster/settings { "transient" : { "cluster.routing.allocation.enable" : "none" } }
2. kill $pid
3.Repair node machine failure
4. /bin/Elasticsearch -d
5.PUT /_cluster/settings { "transient" : { "cluster.routing.allocation.enable" : "all" } }

@GaiserChan

ES version:7.5.1
kibana version:7.4.2

Both of these are EOL and you need to upgrade please

Also, you should really be running Elasticsearch and Kibana at the same minor version, not mixed ones. Different patch levels are ok.

But I can retrieve the corresponding monitoring data through the query, and the monitoring dashboard has always had data before.
