[Nagios-users] check_http SSL cert. date format
Making the date format for check_http --ssl configurable has been requested for quite a while now, but it hasn't seemed to bother any committers enough to ever fix it. I fixed it a while ago on my local copy of check_http (didn't make it configurable - just hard coded what I wanted in place of the hard coded us format) but today I decided I'd make it configurable. It'd be nice if it'd just read a date_format= line from nagios.cfg but it seems that nagios plugins exist in quite a separate universe from nagios and that isn't easy - I'd be delighted if somebody would tell me I'm wrong. So, I've made each of check_http, check_smtp and check_tcp now take a --date-format flag, with allowed values the same as those in the nagios config file i.e. us (MM-DD- HH:MM) euro(DD-MM- HH:MM) iso8601 (-MM-DD HH:MM) strict-iso8601 (-MM-DDTHH:MM) Note that I've dropped the seconds value as it's apparently not available. They also take a short option of -o which was decided on from the few available in each of check_http, check_smtp and check_tcp . Is there any interest in taking these changes back into the plugins source? If so, who would I send them to? I made the changes in a copy of nagios-plugins-1.4.16-89-gbfe6 and I just cloned the git repository and see there are quite some changes in that compared to nagios-plugins-1.4.16-89-gbfe6, but I doubt it'd be too much effort for me to redo my changes in the current git tree.

[Nagios-users] Checking for a string with spaces with check_http in 3.5 / 4.0
I am currently running 3.2.1 (version packaged with Debian squeeze) quite
happily but I want to migrate to a new server so I decided I'd move to 4.0 as
well. I compiled 4.0.0-beta1 and after a bit of a slog finally have it mostly
working. I'm currently trying to get check_http to check for strings with
embedded spaces e.g. check that a page includes the string My Wonderful Web
Site but for the life of me I can NOT get it to work. On 3.2.1 I have this
command definition
define command{
command_namecheck_http_string
command_line/usr/lib/nagios/plugins/check_http -H $ARG1$ -w $ARG2$ -c
$ARG3$ -s $ARG4$
}
and service definitions which include check_command lines like this:
check_command check_http_string!my.wonderfulwebsite.com!60!90!\My Wonderful
Web Site\
and that works as expected, but the exact same thing does not work in 4.0.0
I have tried single quotes, and double quotes, in both the command definitions
and the service definitions. Seeing the error messages in the services seemed
to indicate that the quotes were getting included in the string, hence not
matching, I changed to escaping the spaces in the service definitions and this
worked, somewhat. I'm testing 4 services with check_http_string of which 3 are
identical frontends to the same website and yet of those 4 services, all but
one fails, and the one is one of the three identical servers.
As this struck me as more than a little bizarre, I decided to give the latest
stable Nagios, 3.5.0, a try. With that I was able to use the same config files
as with 4.0.0 and now, all 4 services pass.
Apart from what do you expect from beta software can anybody make any
suggestions?
Kindest regards,
Niall O Broin

[Nagios-users] Nagios showing OK for service which is in CRITICAL state
Had a bit of a panic this morning to get into the office and see that an SSL cert. had expired.

Sure enough, I did, but Nagios wasn't displaying an alert for its expiry, nor had it warned me that it was about to expire.

What plugin are you using ? it could be that the text returned from the check includes the Critical string but the execution exit code is 0 and hence translated as OK by nagios My bad - I should have mentioned that I had already checked that - I am using the standard check_http plugin. But your asking that has anyway solved the problem, because it jogged my mind somehow. The check_http plugin outputs dates in U.S. format, and this is not configurable. I had a command definition which passed the output of the plugin through, so what Nagios was getting back was the result code from sed and not from the plugin. I've now written a little wrapper script which saves the result code and all is now sweetness and light. It would be nice if check_http's date output format were configurable :-( Kindest regards, Niall O Broin -- Monitor your physical, virtual and cloud infrastructure from a single web console.

Re: [Nagios-users] Keeping the Nagios Configuration Sane
On 10 Mar 2010, at 18:58, David Wallis wrote: I manage the Nagios installation for 3 different domains at work, each domain with several hundred servers and clients. I quickly reached the There's got to be a better way! point when trying to maintain configuration files that were getting pretty big. I was using all the tricks listed in the Nagios docs, but it was still pretty crazy. The approach I took was to write a configuration generator program that uses a meta-config file to generate the hosts.cfg, hostgroups.cfg and services.cfg config files. The meta-config file allows one to set up cascading configuration variables, and then has one line per monitored host, that includes things like host groups, parents, etc, and then a list of services to monitor. I also created the idea of meta-services that allow the program to generate configuration data for any number of related services with a single service name in the meta-config file. For instance, including the service weball will cause the configuration generator to create service entries for every plumbed interface on the web server, checks for every virtual server (http and https), and checks for every SSL cert that it finds. In one domain, a 400 line meta-config file generates a 20,000 line services.cfg file. Rather than updating individual config files, I just update the meta-config file and then regenerate all of the *.cfg files. I've been using this for several years with very good results. That sounds very interesting David.

[Nagios-users] Playing alert sounds in Safari
Is this possible at all? When I have an active alert, which should play a sound, I get this popup when I visit the tactical overview page: Safari can't find the Internet plugin. The page Nagios has content of MIME type application/wav. Because you don't have a plug-in installed for this MIME type, this content can't be displayed. However, I DO have such a plugin installed - Quicktime, and it plays wav files just nicely, and if I use Safari to get /media/hostdown.wav from my nagios server, it plays just nicely. I got that file with wget and I noticed that the MIME type it was sent with was audio/x-wav so I edited the binary of tac.cgi to send audio/x- wav rather than application/wav (yes, I know, but it was quicker than getting the source, and building it, just to try this out) but although that got rid of the warning pop up, it still got me no sound.

[Nagios-users] Hostnames and regex
I recently changed a Nagios configuration to use a regex with
hostnames but it hasn't been entirely satisfactory. I have e.g.
define service{
use generic-service
host_name host*
service_description Total Processes
check_command snmp_procs!120!150
but for some hosts, I need to use different thresholds. I tried to use
define service{
use generic-service
host_name hostNN
service_description Total Processes
check_command snmp_procs!200!250
but hostNN still alerts based on the host* thresholds. I tried placing
the definition for host NN before AND after the host* definition - it
made no difference. From what I read of Nagios regex, they're not full
regex so it wouldn't be possible to write one which matched host* but
didn't match hostNN.
Is there a way of doing what I want, apart from the obvious one of
renaming the hosts which I don't want to match the regex?

So I want to ask if anyone here is using nagios with VM and can share about some tricks in deployment? We use Nagios to monitor a number of servers running Xen, and to monitor the Xen VMs. There's no question of installing Nagios in each VM, just as you don't need to install Nagios on each real server you monitor. Instead, you have to install something which can respond to Nagios queries on each VM. We choose to run snmpd on each VM but you can use other methods too. If you instead don't want to run anything on the VMs then you'd be restricted to running some scripts on the hos which tell you the status of the VMs - perhaps somebody already has a plugin to do that.
