Re: [Nagios-users] How to reschedule multiple/all services at once
Scalability might still be an issue with Multisite, there are some things that
make it perform really slow to be aware of, but I have it accessing 34 nagios
servers, about 36,000 devices and 1.5 million service checks, so it's
definitely do-able.

Just attached Andreas' response from another thread.
@Dan, I've taken a look at Multisite. It seems to have some crazy batch
commands/comments which are exactly what I am looking for. I tried it a bit but
ended up getting segfault from apache when I accessed the webpage
localhost/check_mk/. It's probably because I have too many sites running on my
test box. Will try again later. Thanks for the recommendation.
@Michael, Icinga would be good if I started from sratch. It is pain for me to
migrate everything to Icinga though because the default file structure is
different and the web ui is not as straightforward as Nagios core. Thanks for
showing me the OMD, didn't aware of it at all.
@Andreas, I am defining large number of hosts as = one thousand, and each
host is likely to have +/- 10 services, so you get the idea :) I agree with you
that Thruk doesn't look as good as others, so I am looking into Check_MK
Multisite as it has some pretty useful commands/shortcuts/features. I don't use
the report feature that much, so Multisite should be good enough. Yeah,
hacking the cgi is really undesirable. I will just try to adapt anohter UI like
Multisite.
Thanks for all the response!

I usually combine the classic external command scripts with a smidge of perl to

If you give the following script a hostgroup name, it will grab the members
from objects.cache:
#!/usr/local/nagios/bin/perl
use warnings;
use strict;
my $hostgroup = $ARGV[0];
# here's the spot where I should be checking that $hostgroup is defined...
open my $objects,'','/usr/local/nagios/var/objects.cache' or die Failure

my $members = $1;
my @members = split /,/,$members;
for my $member (@members) {
print $member\n;
}
}

close $objects;
When you run that you get a list that you can feed to your external command

Here's the idea in shell on the command line:
bash# for x in `get_hostgroup_members big_switches`;do trigger_service_script
$x;done

Thanks for the recommendation. multsite requires mk_livestatus as core neb module. keep that in mind when installing it. ah well, and it's python. that could be the problem on your apache. best will be to debug it on the logs and report back to developers. @Michael, Icinga would be good if I started from sratch. It is pain for me to migrate everything to Icinga though because the default file structure is different and the web ui is not as straightforward as Nagios core. Thanks for showing me the OMD, didn't aware of it at all. migration is not really painful when you know the right docs to read (i won't post them here, see the official docs). that comes to mind when reading omd as well where the file structures remains even more different (site based), but that's one of those things being traversed into a benefit of keeping different sites for testing and having one as production setup - and doing other upgrade stuff. icinga webui - there are 2 of them (new idoutils based and old classicui, having 2 developer teams on the project). when comparing icinga's classic ui to nagios classic ui, compound commands is one of those things people are asking a lot about (mostly for acknowledging problems, but also to schedule checks or downtimes). to be honest, i couldn't work with nagios classic ui again if someone would pin me other there. but that's just my humble opinion and not really liked ;) as remarked by andreas, nagios developers do not seem to have the intention to feature enhance the classic ui so it will be a dead end requesting features like compound commands. patching that is not really funny, but you can meet rune or ricardo on irc.freenode.net and ask by yourself ;-) generally speaking you should give the omd setup a test install and then decide what to do. if you now stick with nagios core 3.2.3 and wait for a 3.4.x stable release until you test various other guis and tools, wouldn't make much difference then not doing it ;-) @Andreas, I am defining large number of hosts as = one thousand, and each host is likely to have +/- 10 services, so you get the idea :) I agree with you that Thruk doesn't look as good as others, so I am looking into Check_MK Multisite as it has some pretty useful commands/shortcuts/features.

I will just try to adapt anohter UI like Multisite. even if thruk doesn't look that good, it is feature rich and sven is a good developer responding fast to ideas and demands. and from what i have seen, you can use other templates as well - perl catalyst power. someone might have wanted a mindmap or an integrated config editor as well - he added that to thruk. irc or the nagios portal might be the best address to discuss such topics though. kind regards, michael Thanks for all the response!

It's being demanded as multiple addresses for one host which comes to mind when seeing a host as - management ip, and a bunch of service ip addresses (for naming purposes custom vars will be better) - vmware / xen cluster with more than one unique address - dualstacked ip addresses as well as other examples.

(maybe git solves it ;) Until such a time, custom variables, plugin hackery and check command voodoo seems to do the trick for most people. Yep that's true. Adding the address6 patch was solely for the reason of integrating our management databases better into the network and server monitoring.
