This is a list of directives which are only into Metronome or different from Prosody.

General Metronome Directives ~

  • metronome_max_files_soft: set soft limit for files which can be opened by the server process. Default: 9216.

Metronome already by default uses optimized values which are best suited for almost every operation case, changing this wrongly can possibly cause a warpcore breach!
