Just curious: does anyone know how Xymon retains host / service state information between reboots of the Xymon server? I mean, if you have Host_A with services in various states, and then you bounce the Xymon server, does the server re-acquire all the services / states for Host_A from scratch, or does it retain any state information from somewhere on disk?
xymond is (normally) configured with the --checkpoint-file and --restart options set, which specifies the location of the file where all of this is saved between restarts.
'man xymond'
--checkpoint-file=FILENAME With regular intervals, xymond will dump all of its internal state to this check-point file. It is also dumped when xymond terminates, or when it receives a SIGUSR1 signal.
--checkpoint-interval=N Specifies the interval (in seconds) between dumps to the check-point file. The default is 900 seconds (15 minutes).
--restart=FILENAME Specifies an existing file containing a previously generated xymond checkpoint. When starting up, xymond will restore its internal state from the information in this file. You can use the same filename for "--checkpoint-file" and "--restart".
