Disable Kernel symbol unavailable log #85

Closed KaczDev closed 1 year ago

KaczDev commented 1 year ago

Hi, Is it possible to disable / hide this log from the agent?

[WARN] Kernel symbols are unavailable due to restrictions. Try
  sysctl kernel.kptr_restrict=0
  sysctl kernel.perf_event_paranoid=1

I am using the tracing integration with opentel. https://pyroscope.io/docs/java-tracing/

It's probably coming from here. https://github.com/async-profiler/async-profiler#basic-usage

AP has loglevel argument, I will need need to pass it from pyroscope to AP.

In the meantime I suppose you can switch to itimer instead of cpu

fixed in #91

You can suppress it with PYROSCOPE_AP_LOG_LEVEL="none" or PYROSCOPE_AP_EXTRA_ARGUMENTS="loglevel=none" or PYROSCOPE_AP_EXTRA_ARGUMENTS="alluser"
