What is TailWatchd?

Tailwatchd is a technical driver which monitors the logs in cPanel for any error. It also monitors the cPanel modules like chkservd, cpbandwd, eximstats and so on.

Earlier, there were three daemons who would collect information on mail and bandwidth logs. They were antirelayd, eximstats, and cpbandwd.

But now, they are deprecated. So, tailwatchd manages all the services done by these daemons.

Actually, the tailwatchd is much better as it is more robust and lightweight. Also, they reduce the server load to a great extent.
