[Nagios-users] Application monitoring using Nagios!!!
Hi, I am using Nagios Version 3.0.6 on a Linux server. Please let me know whether we have an option of configuring the credentials so that Nagios will automatically login to an application and send an alert on success or failure. Thanks, Ravi G -- Forrester recently released a report on the Return on Investment (ROI) of Google Apps. They found a 300% ROI, 38%-56% cost savings, and break-even within 7 months.

This isn't weird. That's how it should work. kill -9 sends an uncatchable, compulsory, kill signal (SIGKILL) to the process giving it no time to clean up before exiting. The default kill signal is SIGTERM, which can be caught and handled (or ignored) by the process. Restarting Nagios from the web interface, doesn't terminate and restart the process (the PID doesn't change), only re-initializes it. -- Forrester recently released a report on the Return on Investment (ROI) of Google Apps.

Re: [Nagios-users] Nagios kept from restarting after reboot by lockfile
Good stuff, Dan. I was not aware of the differences between how the reboot and shutdown commands handle the reboot process. Turns out that we're doing a reboot -f, which explains why I have orphaned PID files laying around. I'm going to make the call right now that to fight the fight to have 'reboot -f' changed to the plays-more-nicely-with-others "shutdown -r" is already lost and I'm going to work around that in code. Thanks for helping clarify this. It's weirdwhen I run nagios and kill it with -9, it leaves the pid file in tact, but when I restart it, it zero's out the pid file and starts just fine. when I just kill it with the default kill signal, it removes the pid file. In any case, I now know what the issues are and how to address this. Thanks again very much for you help, guys. You are a feature of Nagios.

[Nagios-users] Nagios Windows Check_NT
Hello,
Hopefully someone can help me out, I am setting up Nagios on an Ubuntu
box to monitor Windows servers,
Check_NT is not playing ball, when it is scanning services it is coming
up with :
NSClient++ Version
UNKNOWN2010-12-21 17:04:060d 0h 0m 4s 4/4
Usage:check_nt -H host -v variable [-p port] [-w warning] [-c critical]
C:\ Drive Space
UNKNOWN2010-12-21 17:05:310d 0h 0m 9s 4/4
check_nt: Could not parse arguments
I am using the package install which is version 3.2.1, the test machine
is just an XP desktop that I am trying to get Nagios to pick up. I have
installed NSClient++-0.3.8-Win32 on the client machine with pretty much
default settings aside from the only machine that is able to access it
is the name of the ubuntu machine, taking this out doesn't make a
difference.
Commands I am using (which are just copied straight from templates) :
define command {

[Nagios-users] Nagios Looking Glass Filters
Has anyone had success with the NLG version 1.1.0b? I've been working with it and see some odd behavior while trying to set up host filters. I've read through the FILTERS_HOW_TO.txt file and was successful in creating one additional filter to the default set, but since then have not been able to update the filters, no matter how I edit the server version of s3_filter_inc. The odd thing is that I can successfully change the name of the filters in the list, but can't seem to effect the actual content of the filters. Thoughts? Thanks.

Ok, no problem - create a new contact/contact group, then add them to whatever

"contact_groups"...
like this:
define service {

check_period24x7
max_check_attempts 5

}

Re: [Nagios-users] Nagios kept from restarting after reboot by lock file
I didn't realize that it was so difficult to associate the process with the PID. I'm used to perl, and solutions like this are generally pretty portable. Both your solution and Mikes make perfect sense. I was hoping that I had missed something and wanted to get the skinny before I start actually doing work to get around this. I'll just add the process checks to the wrapper script that runs Nagios. WRT the complexity of Nagios and config editors, I've looked a several, and they do seem to provide some pretty straight-forward configuration help. I don't think our environment is quite so simple. We've got about 4 major applications, each of which has multiple services associated with it as well as different support organizations, so we've got a fairly sophisticated setup. To make matters even more interesting, for at least some of these services, the hosts on which they run -- and often the ports -- change on a regular basis, so we're looking toward writing some templated solutions to generating the configurations for Nagios...which, as you can imagine, provides some interesting challenges. Anyway, thanks, folks, for your help. Much appreciated.

Re: [Nagios-users] Nagios kept from restarting after reboot by lockfile
So are you using the actual "reboot" command not "shutdown -r now" which is a little friendlier? The standard nagios shutdown script should take care of cleaning those up for you. Otherwise putting something like: rm -f ; service nagios start in your rc.local would take care of it. But when you mention pid file, are you saying the PID file is still there, or the lock file? Since they are different things. Again though, if nagios it shutdown properly you shouldn't be seeing that.

I used to price myself in keeping my boxes up as long as possible, but having spent years now supporting mission-critical financial production applications, I'm on board with the weekly reboots. Lets you know early if some system or app change is problematic. Reboot is being done via a standard reboot command. I've looked around for rc scripts that might address this issue, but haven't found any. Got any pointers? Regarding the rc.local solution, a) I'd prefer to solve the problem, not just address the symptoms, and b) elsewhere in this thread I've described the roadblocks that we have to doing anything a system level. Yep, that's right, boys, we survive in the app developer layer within which we do not have root on these boxes. It's a tedious, time-consuming, frustrating, productivity-killing endeavor to do just about anything you can't do yourself. Sogot any sample RC scripts, or command line params to nagios to make it smart enough to know that the PID that is in it's PID file isn't an active process? Thanks.

I think this usually means that the host 'pm2fwi' is not defined in your Nagios configuration. I expect you might be looking for a slight typo in the hostname for example pm2fwl rather than pm2fwi or somesuch. The kind of mistake I usually make is I set up a new directory with host and service definitions in it then forget to add a cfg_dir directive in nagios.cfg. -- Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

Sometimes people use alternate names, and confuse with the fact that if host_name is used, then NAGIOS does not use DNS names.

[Nagios-users] Centreon installation question
I don't know if anyone on the list uses Centreon web front-end, but I have a question. I have to install and set up a new Nagios server. I have already installed RHEL5, now I'm trying to get the base packages (Apache, PHP, MySQL) that are needed. I have been trying to follow the directions here: http://en.doc.centreon.com/Setup:Prerequisite/Centos/Fedora/RHEL and here: http://www.nagioswiki.com/wiki/index.php/Installing_Centreon_on_Centos_5 But they conflict and both bring me to the same point: the major packages don't seem to be there. I can set up Yum and install a simple package such as htop from their repository, but the major packages such as Apache, MySQL, and PHP don't seem to be there. I've even gone out manually to look for them, but they're not there: http://apt.sw.be/redhat/el5/en/i386/dag/RPMS/ or here: http://packages.sw.be/ Does anyone have any experience with installing Centreon?
