We got a problem.
Metricbeat writes data randomly even though the period=10s in case the query instance is set to all "*". The data are recorded randomly for specific instance, but not every 10 seconds.
If I set the query instance to a fixed instance e.g. "_Total" data comes exactly every 10 sec.
Tested and noticed problems for metricbeat versions 7.4.x, 7.8.x, 7.9.x.
However, it works until version 7.3.2.
The servers are not overloaded.
We have the same problem on all ElasticSearch environments where is metricbeat version higher than 7.3.2.
