I'm just curious what it means in the documentation when it's talking about monitoring a FIFO?
I'd kind of like to be able to monitor a stream of logs for particular recurring errors and take an action on that. This sounds like FIFO, but I'm not sure.
Monit is referring to a "First In, First Out" queue:
a method for organizing and manipulating a data buffer, where the oldest (first) entry, or 'head' of the queue, is processed first.
See FIFO for more information
