Profiler

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.

# Module Name

libpipewire-module-profiler

# Module Options

- 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

# Config override

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
}

# Example configuration

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
}
}
]
