I'm using mon to monitor > 600 hostgroups, with an average of 8 or so
services each. The total number of hosts is > 1000.
The main problem I've come accross is that mon.cgi is slow, and after some
debugging, it seems that it's the communication with the mon-server that is
slow. I have to wait an average of about 12 seconds per pageview.
I've tried digging around a bit, and it seems that it's two routines in
query_opstatus that takes quite a long time:
%op_success = &mon_list_successes;
%op_failure = &mon_list_failures ;
Looking at the communication protocol, it seems that the main drawback is
that mon has to spin through a *lot* of data-structures and present them in
a nice way.
I was thinking that this might accomplished faster by sharing the %watch and
maybe %groups data-structure from mon, with the help of
http://perldoc.perl.org/Storable.html .. but even though I feel I have
decent know-how of mon-internals, I don't feel they're entirely up to
scratch on how to implement this.
Is it a good idea? A horrible idea? Am I barking up the wrong tree, with
something else being the main problem here?
