Hi Mathais

Thanks so much for this info, check_mk is looking more and more like a
solution for us.

I may have a few more questions for you but will send them over during the
week as I start investigating more of the possibilities of CK

Cheers

Mike

Hi Michael,

I’ve only just started to play around with check_mk and I have to say I
am impressed by the ease of setting it up and the power of it. but I
wanted to ask one question

The answer is simple: just as Nagios, check_mk reads in all files
in a subdirectory of that where main.mk lies. Usually this is
conf.d/. All files in there named in *.mk are read in *after*
main.mk.

Details are discussed here:

http://mathias-kettner.de/checkmk_configfiles.html

After a change to files there, you need to regenerate
the Nagios config files and (of course) restart Nagios.
This is done by a simple 'check_mk -R'.

Greetings,

Mathias

Is it possible to get the main.mk file to reference other files that
hold config data?

The reason I ask is we are currently using nagios to monitor virtual
servers that are spun up and destroyed on a fairly regular basis, so for
each server that is provisioned we write a separate nagios config file
and drop it into /usr/local/nagios/etc/objects. This config file
includes all data for that image (host, hostgroup, contact and service
checks), this means we can create the configs programaticly on a
provision and restart nagios for it to be read in and when the virtual
server is no longer needed the config file is just deleted from the file
structure and nagios restarted.

What I would like to do is a similar process for check_mk so we would
have a config per server that includes the hostname and ip address as
well as any specific host_group, parent info etc and somehow have
main.mk read this data in when it’s called

So is this possible?

Cheers

Mike
