Measurements:

Jolokia plugin produces one measure for each metric configured, adding Server's name, host and port as tags.

Given a configuration like:

[jolokia]

[[jolokia.servers]]
  name = "as-service-1"
  host = "127.0.0.1"
  port = "8080"

[[jolokia.servers]]
  name = "as-service-2"
  host = "127.0.0.1"
  port = "8180"

[[jolokia.metrics]]
  name = "heap_memory_usage"
  jmx  = "/java.lang:type=Memory/HeapMemoryUsage"
  pass = ["used", "max"]

The collected metrics will be:

jolokia_heap_memory_usage name=as-service-1,host=127.0.0.1,port=8080 used=xxx,max=yyy
jolokia_heap_memory_usage name=as-service-2,host=127.0.0.1,port=8180 used=vvv,max=zzz
