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!

Pretty much all other UI's but the basic one has this capability. Speedwise,
I'd imagine Thruk and Multisite would suit you very well. It sort of depends
on how you define "large number of hosts and services" though. Most UI's
scale just fine to a couple of thousand hosts, although certain parts of it
might suck donkey balls with huge networks. Multisite suffers when creating
reports, for example, but is crazy fast at showing current status. Thruk is
faster at both (last time I checked), but it's, imo, pretty ugly (sorry Sven)
and lacks a bunch of boss-bling type features that other UI's have.
YMMV.
As for adding that capability to the "default" ui; That's not going to happen
unless someone provides a patch for it. None of the maintainers have any
interest in adding features to the cgi, so they're there simply as a fallback
and will most likely be removed some time in the future in favour of a ui
written in some more easily hackable language.

Considering the successes of the wars on alcohol, poverty, drugs and

I usually combine the classic external command scripts with a smidge of perl to
grab the members of the hostgroup that I want to trigger something for.
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
opening objects file: $!\n";
$/ = '}';
while (<$objects>) {
if (/hostgroup_name\s+($hostgroup)/gs) {
/members\s+(\S+)/gs;
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
script.
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

I have seen a pretty good idea on Icinga, a Nagios fork, for this purpose. It
has a checkbox associated with each service check and a select-all checkbox to
select all checkboxes.
hehe. you just made ricardo and rune proud :-))
It would be useful to have that on the Nagios Core, but AFAIK there isn't any.
for the problem itsself - try OMD. nagios, icinga, shinken as core available
whilst the gui decision is up to you.
