When use the java agent there are too many MetricFamilySamples$Sample in the heap
See original GitHub issueI used the javaagent to get some metrics like java -javaagent:/opt/jmx_exporter/jmx_prometheus_javaagent.jar=8080 ..., the version is 0.8.0
With the service running day by day we found the CPU usage is increase like this
And I checked the GC rate trend is same with the CPU increase.
And then I used the command jmap -histo:live 1 to find there were more prometheus jmx relative objects. I am not sure is there an memory leak or it is normal case.
And after I restarted the service and use jmap again, I can not find too many prometheus objects.
