Go Performance Profiler

Go Performance Profiler Extension

The Go Performance Profiler Extension can be used to enable the Go Performance Profiler, also known as pprof, for a Collector. It configures an HTTP server that exposes runtime profiling data in the format expected by the pprof visualization tool.

Configuration Table

Parameter	Type	Default	Description
listen_address	`string`	127.0.0.1	The IP address or hostname to bind the profiler to. Setting to `0.0.0.0` will listen to all network interfaces.
tcp_port	`int`	1777	The TCP port to bind the profiler to.
block_profile_fraction	`fraction`	0	The fraction of blocking events that are profiled, must be a number between 0 and 1. A value of zero will profile no blocking events.
mutex_profile_fraction	`fraction`	0	The fraction of mutex contention events that are profiled, must be a number between 0 and 1. A value of zero will profile no mutex contention events
should_write_file	`bool`	false	If true, the collector will write the CPU profile to a file on shutdown.
cpu_profile_file_name	`string`	$OIQ_OTEL_COLLECTOR_HOME/observiq-otel-collector.pprof	The file name to write the CPU Profile. The default is `observiq-otel-collector.pprof` written in the Collector's home directory.

note

The CPU profile file is only written once the Collector has been stopped and the should_write_file parameter is set to true.
