import { Aside } from '@astrojs/starlight/components';

<Aside type="tip" title="Experimental"> This flag is gated behind the [`profiling`](/reference/experiments/active#profiling) experiment. Enable it with `--experiment=profiling` or `TG_EXPERIMENT=profiling`. </Aside>

Write a goroutine profile of the Terragrunt process at the end of the run. It contains stack traces of all goroutines, which is useful to inspect what goroutines are blocked or running.

Analyze with:

shell
go tool pprof terragrunt_goroutine.prof

When using --profile-dir, the file is written as terragrunt_goroutine.prof inside the directory. An explicit --profile-goroutine path is used as-is and is not placed inside the directory.
