libpipewire-module-profiler - Man Page

The profiler module provides a Profiler interface for applications that can be used to receive profiling information​.

Use tools like pw-top and pw-profiler to collect profiling information about the pipewire graph​.

libpipewire-module-profiler

• profile​.interval​.ms: Can be used to avoid gathering profiling information on every processing cycle​. This allows trading off CPU usage for profiling accuracy​. Default 0

A module​.profiler​.args config section can be added to override the module arguments​.

# ~/​.config/pipewire/pipewire​.conf​.d/my-profiler-args​.conf

module​.profiler​.args = {
    #profile​.interval​.ms = 10
}

The module is usually added to the config file of the main pipewire daemon​.

context​.modules = [
{ name = libpipewire-module-profiler
  args = {
      #profile​.interval​.ms = 0
  }
}
]
