=0D=0Agreetings, fellow Nagios users.
well, basically I think it's just about time to add a new plugin interactio=
n interface to Nagios.
pretty bold, ha?
now let me explain. it has been almost a year since we turned to Nagios for=
our monitoring needs
(we were previosly using BigBrother and oh my dear, was it awful!)
so we are being almost happy now. however, as configuration continues to gr=
ow, the response time
of the whole monitoring system increases.
currently we have 248 hosts monitored with 755 active checks at a 60 second=
s interval.
(interval_length=3D10, normal_check_interval 6)
being in charge of the monitoring, by now i have done all i could to optimi=
ze plugins,
and in fact this has helped a lot to keep the system running at a decent pa=
ce.
(for example, i have integrated disk checks into one plugin that uses share=
d snmplib
instead of calling snmpget, effectively elimitaing another fork)
so the biggest problem at this time seems to be Nagios's need to launch a p=
rocess for every check.
so now i'm thinking of adding some kind of plugin invocation mechanism into=
Nagios
that wouldn't require starting up another program.
and what i am thinking of as my options are:
1) shared library mechanism, like Apache modules. should be the fastest of =
all, but has its shortcomings.
not very flexible.
2) some kind of IPC. this would involve, i think, some check daemon process=
that'd start with nagios
and respond to check requests from it. a pipe or message queue could be use=
d for communication.
3) just forget about it.
i think i'll do that one way or another. but i want to make it The Right Wa=
y (r) and this is
where i turn to you and ask if you have any ideas/opinions/suggestions and =
in general, if it's worth
implementing at all...
