# pprof
|
|
|
|
## Name
|
|
|
|
*pprof* - publishes runtime profiling data at endpoints under `/debug/pprof`.
|
|
|
|
## Description
|
|
|
|
You can visit `/debug/pprof` on your site for an index of the available endpoints. By default it

|
will listen on localhost:6053.

|
|
|
> This is a debugging tool. Certain requests (such as collecting execution traces) can be slow. If
|
|
> you use pprof on a live server, consider restricting access or enabling it only temporarily.
