Pyroscope with Java

[maheshrajrp]

Hi All,
I am trying Pyroscope with Java, I am able to successfully get information process_cpu from the application, however, I am targeting for more information on memory. Is it possible ? Does Pyroscope support it ?

Thanks

1. Assuming you are using java sdk
   The documentation is here https://grafana.com/docs/pyroscope/latest/configure-client/language-sdks/java/

1.1 if you run the SDK as java agent , you can use PYROSCOPE_PROFILER_ALLOC=512k configuration to enable memory profiling
1.2 If you run the sdk as java library, you can use the Config$Builder#setAlloc method to enable allocations

2. If you use java profiling from grafana agent (pyroscope.java component), then you can use the alloc configuration option. (the docs are here https://grafana.com/docs/agent/latest/flow/reference/components/pyroscope.java/

pyroscope.java "java" {
  targets = discovery.relabel.java.output
  forward_to = [pyroscope.write.staging.receiver]
  profiling_config {
    interval = "60s"
    alloc = "512k"
    cpu = true
    sample_rate = 100
    lock = "1ms"
  }
}

Hi @korniltsev ,
Thanks for responding, I can see the following metrics now. Right, from Java perspective is there any other metrics we can fetch using Pyroscope Agent ? Have I missed anything ?

Is there any simple documentation that explains the possible metrics that can be scrapped ?

Thanks again

You should be able to see supported profile types in our docs here
