mod_log_events_by_memory/README.markdown @ 5931:d194d1012fd3
Updating dox for mod_rest. Ideas expressed / clarified:
1) Making clear that mod_rest isn't to be installed under VirtualHosts AND as a component.
2) Understanding some of the implications of this choice:
A) Changes to user authentication
B) How it affects subdomains
3) More consistent use of domain names for clarity.
4) Using different heading sizes to show scope of section.
Essentially, I added all the tidbits I had to clarify in getting this to work in my
own example.

This module compares the memory usage reported by Lua before and after each event and reports it to the log if it exceeds the configuration setting `log_memory_threshold` (in bytes). ``` lua log_memory_threshold = 20*1024 ``` If you are looking to identify memory leaks, please first read [Three kinds of memory leaks](https://blog.nelhage.com/post/three-kinds-of-leaks/). Prosody runs on Lua which uses automatic memory management with garbage collection, so the numbers reported by this module are very likely to be useless for the purpose of identifying memory leaks. Large, but temporary, increases in memory usage can however highlight other kinds of performance problems and sometimes even provide hits for where to look for memory leaks.
