  • Monotonic and Variable values are shipped in all collection time.
• If you want to calculate these values (e.g. ratio, time), you have to implement it in your client apps.

• Collects values for multiple Java processes or for a given PID
  • When a PID is not given, it collects counter values from all running Java processes that create a hsperfdata file under /hsperfdata_*

$ go get github.com/YaSuenag/hsbeat
$ hsbeat -E hsbeat.modules.0.pid=<PID>

Collecting counters from all running Java processes

$ go get github.com/YaSuenag/hsbeat
