Filebeat monitoring problem

[pauldon2 (Павел Шевцов)]

I tried to enable filebeat monitoring on elasticsearch.
Enabled it in the configuration:
xpack.monitoring:
enabled: true
elasticsearch:
hosts: ["http://10.10.8.77:9200"]
Thus configured 8 servers. But in kibana I see only 2.
The remaining logs from these servers are transmitted normally.
In the index .monitoring-beats- * I see data from all 8.
What could be the problem?

P.S.
Licensed on elasticsearch - basic.
Version elasticsearch and kibana - 6.4.2.
The filebeat version is 6.4.0.

P.P.S.
In ealsticsearch cluster - i have next settings
"persistent": {
"xpack": {
"monitoring": {
"collection": {
"enabled": "true"
}
}
}
},

Where in Kibana do you only see the 2? You said that the indices have the data, but it sounds like some view doesn't show it. Is that correct?

[pauldon2 (Павел Шевцов)]

I created a .monitoring-beat- * index. In it, I see data from all servers.
But I always see only two servers in the monitoring section. (And at the same time different).

Is anything, on the beats side, looking amiss in the logs? Any errors present?

[pauldon2 (Павел Шевцов)]

No. Not present any erros messages in filebeat log's.
And even more - all the logs from these hosts are transferred without problems.

So, out of curiosity, have you tried connecting those instances to a local Elasticsearch / Kibana installation?

This scenario is quite perplexing. With no errors, there's not much to follow-up on here. Let's see if we can get things working in some sense, then work backward to a cause.

Currently my ELK cluster is collecting logs from about> 200 servers. I had no problems with the collection and processing of data. Problems are only the display of information in kibana with monitoring filebeat. To begin, I set up data collection from 8 servers. But as you can see information is displayed only from 2 of 8. And the most interesting is that these servers are different all the time.
