Gunicorn with multiprocess tmp folder cleanup

[shubhbuz]

Problem statement : I have multiple workers emitting metrics using multiproc enabled in a fastAPI server . I want to know is there an ability inside prom client to enable file rotation to avoid increasing the disk space . If not what is the best way to do cleanup .

Constraint : I can't restart my process/server as there is going to have continous traffic.

What i have tried : I had a cleanup script running every XX hours to remove the db files created but new files doesn't gets created as i believe that happens while worker is starting .

Not full cleanup, that is only really done on restarting the process/server. #568 is the long standing issue for this, a solution would be great but most have various tradeoffs.
