Mythlogserver
From MythTV Official Wiki
mythlogserver is a program added in the 0.26 release.
Log messaages generated by MythTV programs are sent to
mythlogserver.
It is started automatically when existing MythTV programs start,
typically mythbackend and mythfrontend.
See 0.26 specific notes in Logrotate All Applications.
The log server uses ZeroMQ libraries, which are included with the MythTV distribution.
