Original Pull Request: https://github.com/netbirdio/netbird/pull/3683

State: closed
Merged: Yes

Describe your changes

This allows us to generate debug bundles when the process is stuck or local grpc is not available (containers).

Example usage:

$ docker exec -it  55725223f383 pkill -SIGUSR1 netbird

$ docker logs 3332a2a01acb 2>&1 | grep SIGUSR1
2025-04-15T13:15:29Z INFO client/cmd/debug_unix.go:34: Received SIGUSR1. Triggering debug bundle generation.
2025-04-15T13:15:34Z INFO client/cmd/debug.go:361: Generated debug bundle from SIGUSR1 at: /tmp/netbird.debug.3539742972.zip

$ docker cp 3332a2a01acb:/tmp/netbird.debug.3539742972.zip .

On Windows:

[Environment]::SetEnvironmentVariable("NB_LISTEN_DEBUG_EVENT", "true", "Machine")
netbird service restart
$evt = [System.Threading.EventWaitHandle]::OpenExisting("Global\NetbirdDebugTriggerEvent")
$evt.Set()
$evt.Close()
