Description
This issue has been migrated from [#13351](https://github.com/matrix-org/synapse/issues/13351).
---
We have just had an example on matrix.org where we wanted to add a new user to `force_tracing_for_users` to profile performance problems. We can't do this without restarting workers. It'd be great if we can just ask Synapse to reload things nicely with a SIGHUP.
Contributor guide
Research direction
Start by locating Synapse's force_tracing_for_users configuration and the existing worker signal-handling path for SIGHUP. Determine how configuration is loaded across workers and verify that adding a user to the tracing list takes effect after SIGHUP without restarting workers.
