sigprof

Golang package for inspecting running processes. Similar to net/http/pprof but using USR1 and USR2 signals instead of HTTP server routes.

Usage

Link the package:

import _ "github.com/tam7t/sigprof"

Send the USR1 or USR2 signal to inspect the process.

kill -usr1 <golang process pid>

The default USR1 profile is goroutine. By default, sigprof will save results to timestamped files.

go tool pprof profile-<timestamp>.prof

Configuration

sigprof loads its configuration from the following environment variables.

• USR1_PROF - Profile executed on the USR1 signal. Default: goroutine
• USR2_PROF - Profile executed on the USR2 signal. Default: heap
• SIG_PROF_OUT - Specify the output location, either file, stderr, or stdout. Default: file.
