Nagios is good at what it does, and it really sounds like this just isn't it. However, I don't see a reason you couldn't hack together a really simple check using a tool that *is* good at this sort of thing (like, say, nmap), and based on the results of that tool, feed the results back to Nagios . I would say that the best thing to do would be to turn off dhcp on that router and use dhcpd instead. Open and accessible and then you can just use the plugin I wrote... at least I think that would be least amount of work for you to get to working solution. Dhcpd isn't hard and doesn't take long to set up, but I'm not sure on your wording, you mean the hosts aren't under your control or the router isn't under your control to replace the dhcp service with dhcpd? If turning off the dhcp from the router isn't an option then you need to go back to the drawing board, consider how you can access the system, if you have a shell, if you have snmp etc and then come up with another solution using that, possibly custom writing your own plugin to integrate this in to Nagios. -h -- Hari Sekhon http://www.linkedin.com/in/harisekhon -- Come build with us!

Re: [Nagios-users] Question about Nagios Plugin check_svn
Manuel Höbel wrote: Hi Hari Sekhon, I have a question about your Nagios Plugin ‘check_svn’. I only want to check if SVN is reachable. So I only use the Command Line $USER1$/check_svn -H $HOSTADDRESS$ in my Nagios Configuration to do so. But in Nagios, I always get the failure: UNKNOWN: 'svn' cannot be found in path. Please install the subversion client or fix your PATH environment variable Now to my question: Where do I have to change/set the ‘PATH environment variable’? Should I write it in the Command Line, for example: $USER1$/check_svn -H $HOSTADDRESS$ /usr/bin/svn or somewhere in your Plugin File? Sorry, I have no idea and I’m new to the hole ‘Nagios thing’… ;) It would give me great pleasure if you could help me with this little problem. J Hi Manuel, I'm sending this to the Nagios-Users mailing list as well as I think it's a generally useful thing to know/discuss. Firstly, the path is set in the user's profile as per unix standards, so you may want to check the path of the user account that the plugin is running as (if it's running from the nagios server as you imply then this is the user that Nagios itself runs as). Secondly, if you want to change the PATH environment variable to include the directory containing the svn binary only for the check_svn definition then you can try another standard unix trick which is to prepend the environment variable to the beginning of the command line as follows: PATH=$PATH:/path/to/directory $USER1$/check_svn -H $HOSTADDRESS$ which will append the directory /path/to/directory to the PATH environment variable and allow the plugin to find the svn executable. Replace /path/to/directory with the directory where your svn executable is located, something like /usr/local/bin etc... I've noticed that Nagios runs shells for some plugins and not for others. It looks like Nagios runs a shell for anything that isn't an obvious full plugin path... so you can use all sorts of constructs like cd /dir ./plugin _name etc just as you would if you were typing into a shell. rant Probably the only thing I disagree with on the Plugin Coding Guidelines is specifying the full path to any binaries used as this makes things horribly non-portable across distros and platforms which may have programs in different places. I don't think that you should have to be editing plugin code to make it work on different platforms, that's just horrible to maintain if you run more than 1 distro/platform (and a lot of us do). PATH is so standard in unix, we should just use it. Security worries regarding PATH are usually ridiculous since if someone can modify your path, you've got serious problems and inconveniences like hard coding full paths to binaries just isn't going to save your bacon, we don't write /path/to/ls every time we execute it on the command line, do we? end rant Thanks -h -- Hari Sekhon Always open to interesting opportunities http://www.linkedin.com/in/harisekhon -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ 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

Re: [Nagios-users] Best Practises for a *NIX environment over multiple WAN's
I think this screams for an NSCA relay agent so that you don't have to actually have to make the changes on more than 1 nagios server, which is what you'd currently have to do. Such an agent should work just like a dhcp relay, get a request, buffer and try passing it on to the remote nagios server, retry if the wan link is down etc... Alternatively, for right now, a config framework like puppet + revision control + scripted auto update/config change to passive check forwarding on remote nagios server + reload would probably be a workaround to do what you want so you only have to modify nagios in one place and the other follows suit automatically. I love doing stuff like that. -h -- Hari Sekhon Always open to interesting opportunities http://www.linkedin.com/in/harisekhon David Jacobson wrote: Hi There, We monitor a large amount of services for all our customers. We do not have the luxury of all the networks being on the same WAN/LAN infrastructure. A lot of our servers have public IP’s and a lot do not. Typically, we have been monitoring the *NIX servers using a combination of active and passive (active where we can, passive where the server does not have a public IP) What the above creates, is quite a mess and a difficult process to try and explain to all our support agents on how to monitor our customer servers, due to all differences. We are now redoing our monitoring from scratch (using Groundwork) - in an ideal world each server would be accessible via an active check and we could ensure that 99% of all monitoring changes are doing via the Groundwork interface (assuming we run NRPE on each server and have external arguments accepted) - what’s great about this, the junior support engineers could easily make changes via an interface. However, as discussed not all servers are accessible directly, so I’m considering just doing an all passive approach to simplify the process – to install nagios on every server which submits its active checks back via NSCA. The thing I hate about this, is the fact that we have to log on to every server to make a monitoring change, which is what I was trying to avoid. I guess we could make the passive approach a bit better, by making use of something like puppet and version control so we don’t really have to log on to the servers... Before I start this whole project, I would like to know if anyone has any ideas on the “Best way” to do this, any advise would be appreciated.

Switching the host check to a service check, in this case check_http would be more appropriate. -h -- Hari Sekhon - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ 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

Re: [Nagios-users] Linux Disk IO
If you try looking at vgs or lvs you'll fail, iostat will output no stats. You can either look at the underlying pvs or the dms. So figure out what your lvm is sitting on and look at that. Running iostat without specifying targets will list all your relevant underlying partitions which will make it easier for you to see what you have.

I haven't tried it as I don't manually maintain service groups, but consider another way of coming at the problem: If you add a hostgroup to a service, then you can generate the servicegroup around it for web interface usage. This way I don't ever maintain servicegroups myself, they are automatically generated so that I can just use them for grouping views in the nagios web interface.

Re: [Nagios-users] using Linux for a specific Windows Event
Michael, You need to filter on the event you want at the logserver and send it as an email via email/winpop or whatever, this is highly dependent on what logserver you have. I personally think syslog-ng is great (and I use check_logserver from nagiosexchange.org to monitor that for you next question). NTSyslog can send events from the Windows event log to the remote syslog server, and from there you can do whatever you want with it, store it in a database, send alerts off to yourself on certain events etc, it's entirely up to you. -h Michael Dalton wrote: I have but without much or what was there didn�t really do the trick, what would you suggest to monitor a windows event such as that?

2. It checks *LINUX* software raid, not windows software raid.

Re: [Nagios-users] send_nsca
Hi Tony, That's a very good point. It wouldn't be difficult to make this support multiple simultaneous checks, but I currently have the checks running independently of one another and it works very well. This was originally written with the intent to make it easy to take any single check and turn it passive without re-creating the wheel, simply by putting this script in front of it. If you grouped checks then this implies that they must all be run at the same time, which seems to reduce flexibility. Also, I think that for a lot of passive service checks it is advisable to not have them run at the same time. For example, I have check running at different intervals intentionally for staggering on the servers so that there is no performance degradation on the server performing the passive checks, although this could simply be one after the other which also should reduce performance in comparison, but watch out for multiple long running checks as this will may send the check result beyond the freshness threshold.

[Nagios-users] OpMonAgent vs NSClient++ (was Nagios 3.0 SLA Reporting)

I have found that NSClient++ is a doddle to deploy with a batch script across all servers. very briefly: copy over the binary, set the service, run. This is only mildly more difficult than an msi installation, possibly even easier to actively push out via batch in fact. I'm not sure if I considered OpMonAgent but I'd really like to know if it can beat NSClient++ which to my knowledge (or perhaps just perception) seems to be the more popular Windows agent. -h -- Hari Sekhon - This SF.net email is sponsored by: Microsoft Defy all challenges.

Pradeep, Please reply to the mailing-list rather than me personally so that other people can follow the conversation as well as it may benefit them or they may be able to give you further insight/contributions. Now to answer your question: You could probably run Nagios on the workstation edition but the packages on the workstation edition will be more aimed at desktops and workstations whereas Nagios is a server and therefore a server orientated version is preferable to try to keep things a bit tighter as per best practices. For example, on a server, you probably don't want X windows etc as these have no place on an infrastructure server and real sysadmins don't need GUIs. -h Pradeep Pokharkar wrote: Dear Hari Sekhon, Thanks for the quick reply.

Re: [Nagios-users] Overriding interval_length for certain hosts/services

I have a scenario where I need to check an HTTP service in shorter intervals than the other services, which now defaults to 60. You mean you want to have checks run more frequently than every 60 seconds but since this is the interval_length you can only put 1 as the minimum in your service definitions. I changed my interval_length to 1 and then for each service specify it in seconds. This is the only way that I think you can get checks more frequent than once every 60 seconds. In my opinion this should have been 1 by default and all service check intervals should have been specified in seconds since it's not rocket science to use numbers that are like 60, 120 or 3600 for various checks remembering that those are 1min, 2mins and 1 hour respectively. -h -- Hari Sekhon - This SF.net email is sponsored by: Microsoft Defy all challenges.

I guess I should have been more specific, sorry about that.
I am running Nagios 3.0.1 on openSUSE 10.3, and I am only monitoring
windows hosts. On the windows hosts I am running NSClient++. That
seems to work good and I would prefer not to change to any other client.
I have read about the event handlers in the Nagios documentation, but
the samples there only refers to nrpe and scripts on the server. I
understand how to define the service in Nagios, but I am not sure how
to create the script that executes the batch file on the windows host?
Maybe I am not getting the point and understanding on the documentation.
Lets say I created a batch file that will start or restart a service,
this batch file is located in c:\NSclient++\scripts folder. And then
defined the service and command in Nagios:
define service{
host_name somehost
service_descriptionsql-service
max_check_attempts 4
event_handler restart-sqlagent
}
define command{
command_name restart-sqlagent
command_line what do I add here?? It has to be something that can
be sent to the Nsclient++/windows host and execute the batch script in
c:\NSclient++\scripts folder
}
The command line on the eventhandler documentation shows a path to a
local script and local command “/etc/rc.d/init.d/httpd restart”
So creating and event handler for services or others on the box where
Nagios is running, I understand. But not how to do it remotely to a
windows host.
If you could shed some more light over this I would very much
appreciate it.
Thanks,
PJ
You need a Unix-side script to execute and handle the condition
appropriately, for example to only call the restart when the service is
in hard failure. A sample Bash script is given in the docs to get you
started.
If using Bash (which I recommend) the Bash script should check the state
and perform the logic control, calling the batch or script on the
windows side though an NRPE call to nsclient++ to execute the script on
the windows host.

I knew there was a good reason why I had originally done this, I just couldn't remember what it was. Technically this is not the fault of the plugin itself but of yum and I'm not currently sure if this is by design. It appears that the normal user account can only see updates from rpmforge, and not from the official RHEL repository which is where the vast majority of the updates come from. Why this is I have not yet determined, it may be an intentional thing on the part of Redhat in order to try to prevent users from seeing the vulnerable components, although this would be very weak. I have not updated the plugin to force root privileges but I have just made a warning note on the NagiosExchange page telling people that it is advisable to run the plugin as root to be sure to get all of the updates. If I can bend yum to not require root privileges then I'd prefer this as well, but most of all I'd prefer to get all the updates and not have yum lie to me leaving me with an insecure non-updated system. It would have been preferable of the yum writers to make the thing fail outright so we could deal with it more easily than to silently fail leaving us guessing... If anyone has any wisdom they care to share on this, I'd be happy to hear it and perhaps update the plugin accordingly.

Randal, Phil wrote: The latest version now works fine on my CentOS 5.1 boxes. Now all we need is a version which works with python 2.3 so I can check our CentOS / RHEL 4 boxes. Cheers, Phil I have a couple of RHEL 4 boxes too but since they didn't ship with yum this didn't seem so relevant. I tried putting yum on one of them a couple of years back and I have to say it was an absolutely awful experience. I had done a relatively minimal install and was then tryied installing yum both by rpm and by source install, both of which landed me in a very bad and messed up circular dependency hell that I couldn't solve without breaking some other stuff. I mean I tried everything, and that was the last time I ever tried a minimal redhat installation (minimal == lower attack surface and all that best practice stuff which redhat never seemed to get into - otherwise I have to go round disabling so much junk on their systems), a very poor choice for tight control and maintainability compared to gentoo or debian (but I digress). Did you install yum manually on RHEL 4? Do you use this as the primary package management tool on RHEL 4 and does it receive security updates? I would have thought not since RedHat only shipped this in version 5 which is why the plugin makes no effort for previous versions of RHEL... but I could be wrong. I figure that upgrades to the version 5 with it's first half-decent package management system using yum by default will solve this, but if anyone wants to correct me or share their experience, feel free and I may reconsider. -h -- Hari Sekhon - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

I was under the impression that since CentOS is supposed to be purely a rebranded RHEL without the trademark logos etc, that it would follow RHEL closely, so if RHEL 4 didn't ship with yum, then neither would CentOS 4? I guess the CentOS guys realized how big a disadvantage this would be... Did you add yum manually to RHEL 4 and if so, what implications are there for updates then, is there any official repo for that, or only 3rd party. If 3rd party, do they support security information support for yum? Otherwise you'd have to use --all-updates or --warn-on-any-update and keep the whole system up to date if you cannot differentiate between security and normal updates. -h -- Hari Sekhon - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Have you tried yum install yum-security Perhaps the yum-security plugin is not available for install in this version? I can't verify since I don't have any CentOS 4 here. The plugin gives this install tip if the security plugin for yum is not available. I found that it was not installed by default on all RHEL 5 systems but was such a useful thing to have that just running the yum install and then re-running the plugin was worth it for the distinction.

It's not clear though whether or not the 3rd party repos support security package information like yum provides on RHEL 5. You may want to just do a generic --all-updates to return critical for any available update or just --warn-on-any-update to still try to differentiate but warn on non-security packages and upgrade any available packages? I've not managed to get a straight answer out of anyone on how 3rd party repos affect the security of a system with regards to managed security updates. The usual evasive answer is that Redhat only provide support for their limited official repository, but where does this leave people who use all these 3rd party repos to make up for the deficiency of the official repo? This is why I prefer Gentoo and Debian's more comprehensive official repositories that are managed better and have security updates. If anyone knows more about 3rd party repository and security updates this I'd love to hear it as I hate the idea of getting security updates for only a subset of the total installed packages (hence why --warn-on-any-update may be useful to try to get around this) -h -- Hari Sekhon - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

[Nagios-users] Announce: Check_Yum for RedHat/CentOS server package alerts
Hi, I've just released the Check_Yum plugin on NagiosExchange.org as the only one there seemed quite inadequate. Features of the new plugin (none of which are in the old plugin) include: - Differentiate between Security / normal package updates - Better output - numbers of packages updates - Support for extra Yum options including enabling and disabling repos, running from the cache - Optional Warning on non-security updates - Optional Critical alerting on any package - Timeout - Verbosity - Less false package alerts (the old plugin just used to misleading say the O/S needed updates when yum failed for any reason at all), including proper error feedback and a switch for lock handling to not raise an alert like if somebody is running yum interactively at the same time. You can download the plugin here: http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2577.html;d=1 (you may need to copy and paste that link if your mail client misinterprets the link) As ever, feedback is welcome, and development will continue if needed for extra switches and features. This should also work with Fedora or another RPM based distros that uses yum as it's package management system but I've not tested it outside RHEL/CentOS so feedback is welcome there too. On a related note, I'm also quite interested in people's experiences of updating and maintaining RedHat based systems especially with regards to security. I spoke to a few people and they basically don't follow security vulnerabilities and don't patch which ties in with my experiences and what I've seen of other people's systems too which is very disappointing. Hopefully this will make it easier to automatically track and keep on top of security updates for those of us who have RedHat Enterprise Linux 5 or later or equivalent.

[Nagios-users] Nagios Exchange feedback
Hi, I just wanted to give some feedback on the new NagiosExchange site. I'm intentionally posting here and not via the contact form on the site itself because I would like to have an open discussion on this in order to give better collaborative feedback. First off, thanks to all those who had a part in upgrading the site. Some of my own personal observations and opinions on the site and how it can be improved are below if you are interested. 1. The author name is no longer displayed next to the plugins listing. I don't know about anyone else, but I used to really use this to see straight off if a plugin was written by the same guy as another one as there is usually a strong correlation in the quality of plugins and who wrote them, it helped me avoid or zero in on plugins in a list. It's also just nice to see who wrote each one when scrolling through any list. 2. The votes have all been reset, which is a shame since it now means the better rated plugins are mingled in with the not so good ones, and I doubt people are going to go back and re-cast their votes. 3. The wiki markup changed, it would be nice if this was mapped or something on the migration, pages I've written now look horrid and I'd rather not go through so many pages to do it the manual chimp way (although I could live with it if I had to) 4. Navigation doesn't seem to be as nice as it was. For example, the only way to browse the plugins is to go back to the home page and navigate from there. There don't seem to be any links the the top bar of the page, and things like Cool Projects and Random Project, while good ideas, seem a bit less useful that this basic usability in navigation of going straight to the plugins browsing by section like we had before. 5. I get a certificate error when connecting to the site's login, it seems that the certificate is self signed instead of verified by a trusted 3rd party as is standard... Overall, I feel that NagiosExchange is less clear (I can't fully explain this bit - a feeling with the layout, spacing, text etc...) and less effective since it's revamping... I certainly haven't felt as comfortable using it as the old site, either looking for other people's plugins or with my own. I'd like to know what other people think, if anyone agrees or disagrees with what I think on these topics, since this is a community orientated site I thought it might be relevant to have a more community orientated discussion as this is the site's primary audience. Again, thank you for all of your work on NagiosExchange.org to all those involved and also to all the plugin authors as well that make the site such a useful code sharing conduit. -h -- Hari Sekhon - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Re: [Nagios-users] change management or source control for Nagios configs?
Frost, Mark {PBG} wrote:
I'm wondering what most people out there use for change management of
Nagios config files. I had been using BZR (bazaar-ng) for a while, but
when I refreshed my servers it was a bit of a pain and haven't put it
there yet. I've tried to read about other ways to do this (RCS, SVN,
etc), but they all seem so strongly oriented towards source-code
projects that it's kind of confusing to run them with just config files.
Some of these methods are complicated by the fact that they want to make
their archive directory inside Nagios' directory structure. This gets
kind of weird as I use nagios.cfg directives to tell it to recursively
read directories rather than just specifically named files. BZR worked
OK in this regard as it's dir was .bzr and was never picked up by
Nagios.
Ultimately, I'm trying to provide myself with the ability to track
changes and potentially roll them back. Is anyone else out there using
some wonderful solution to this
Subversion.
It's not difficult, you don't have to read all the code concepts like
branching and merging if you are just interested in simple check out -
change+deploy - check in usage.

Nice to see my original bash idea has proliferated...
I actually had this thought last year as well and my original solution
was a very cheap bash script to loop through calls to the different
drive letters, which worked, but was
prone to being sensitive on latency since it had to make many round
trips (The same was true of checking multiple services in this way).
I think it would be better to have a native windows plugin to do this, I
just haven't had time to get round to writing and testing it.
I actually did write a windows plugin for the multiple services check
but have been so short on time that I wasn't able to thoroughly test
every code branch so I didn't release it. (it's similar in code base to
the check all automatic services are running plugin that I released though).
In fact, there are one or two plugins out there that do windows disk and
services, but I didn't like their style, I felt the output was
incoherent with Nagios style leading to a more mis-mashed dashboard
(which I keep on a screen by my desk at all times) and my coding was
more thorough so I didn't use them... but you're welcome to dig them out
and try them if you want. Have a peek at Nagios Exchange.
I'm hoping to get time soon to thoroughly test my services plugin and
also do the disk check plugin too. Stay tuned.

[Nagios-users] Announce: check_svn - Plugin to test Subversion repositories
Hi, I've just released another plugin on NagiosExchange called check_svn that tests subversion repositories over svn://, http:// or https://. This is a re-write of a plugin I've been using for more than a year and had been meaning to release earlier, I know there were some people who had asked for it, and my apologies to those folks for taking so long on this, but work has not allowed me to spend time on the things I've been wanting to and I generally don't release my plugins until I feel they meet a minimum standard. The plugin takes range of options including username/password credentials, port, protocol, directory, directory content listing, timer output. It follows the standard Nagios coding guidelines with a --timeout for the test and levels of verbosity for more information or debugging. It requires that the svn command line client svn be somewhere in the path as it uses this to connect to the Subversion server to fetch a listing to determine that the repository is online and available. You can get the plugin from NagiosExchange: http://www.nagiosexchange.org/Check_Plugins.21.0.html?tx_netnagext_pi1[p_view]=1258 Feedback on this plugin is always welcome.

The problem rises when creating the contacts, because the same contact should be assigned to several contact template, but is not possible. Anymore idea!? Thanks. Sds, If you are trying to do something too complicated, you might be trying to push a square peg in to a round hole by forcing Nagios to work in a way it normally doesn't do. Have you considered just having one notification command which calls a script. You can then program in all the logic in to this script. The script can accept lots and lots of Nagios macros and change the output depending of conditional testing and outputting certain macros with information depending on which host or service it is. This way all the logic is in once place and you just need to maintain that notification script.

So, what is the clue? your nagios configuration is probably wrong, double check your checkcommands.cfg and your services.cfg where you are calling the command. If you are specifying in services.cfg checkcommand check_http!-p 100080 then you will need the command to have an $ARG1$ variable after it in checkcommands.cfg. -h err, correction, that's supposed to be check_command in services.cfg and you'll need a corresponding $ARG1$ on the line command_line in checkcommands.cfg. -h -- Hari Sekhon - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Nagios-users] Plugin Output Standardization (was JMX plugin thread)
Marc Powell wrote: The plugin output text is completely arbitrary. Nagios only really cares about the exit code and that there's only one line of plugin output, whatever it is Yes quite right, but standardization of output is nice for coherence and to give a more professional unified feel. Do you have any preference between the two? There seems to unfortunately be a mix between the two styles. Perhaps the official development guidelines could be adjusted to steel people towards one standard output format on this?

What I had missing? maybe I have to touch a file? sorry but iŽm a little bit
confused today.
You're probably trying it on the command line as root and nrpe is
running it as a regular user that may not have permission to write that
location
Either that or your nrpe.cfg is wrong.

If this is to get a disk check depending on what disks are available,
look here for a tip:
http://www.mail-archive.com/nagios-users@lists.sourceforge.net/msg11936.html
I'm having a problem getting this sort of thing to work
on monitored server (with nrpe) i have the following line in nrpe.cfg
command[check_disks_proc_mount]=/usr/lib/nagios/plugins/check_disks_proc_mount
In my check_disk_proc_mount script (which runs ok on its own), I have
something similar to
./check_disk -w 15% -c 20% $(for x in $(/proc/mounts | awk '{print
$2}'); do echo -n -p $x ; done)
I run this from the command line, and I get my expected DISK OK
return value.
However, I get NRPE: Unable to read output when I run the following
command from the plugins directory from my Nagios server
./check_nrpe -H (ipOfMonitoredBox) -c check_disks_proc_mount
What do I need to do for this to work across NRPE like it does when
I'm shelled in the box?
there is an error in that shell script, the bit
$(/proc/mounts | awk '{print $2}')
is wrong. You might just change it to
$(cat /proc/mounts | awk '{print $2}')
or
$(awk '{print $2}' /proc/mounts)
but I wouldn't recommend it, you should limit the check to real
filesystems like ext2/ext3/reiserfs/xfs etc not things like sysfs, udev
etc..
Try playing with this on the command line until you get it right, you
may want to check the bash docs or ask in freenode's #bash if you're not
strong in bash though (warning: don't ask in #bash until you've looked
through docs or you'll get flamed if it's a simple problem to solve and
it shows you haven't read the docs and tried sufficiently)
Also, try looking at my example again in the original link I sent you
which does exactly what you want, all you need to do is choose the
filesystem types you want to check.

I never got that from the Nagios development guidelines, perhaps SERVICE STATUS: Information text is slightly ambiguous as it could mean SERVICENAME then STATUS then Information text or just STATUS then Information text. I've personally always preferred the former where you print the check name, I think it makes things clearer and I've noticed that lots of the plugins from the standard distribution follow this. To the OP and back on topic, I don't know anything about your plugin but have you tested that this Java program is using the right Exit codes? You should also make sure that all output goes to stdout and not stderr since nagios does not catches stderr. Oliver is right, you should check the user that you are running it as, one common mistake is to run a program as root from the command line and then wonder why it doesn't work as the nagios user. Usually when you get Unknown and no output at the same time with nrpe, it's usually a user issue or a failure to execute issue due to wrong path or requiring more privs or something hanging like a sudo call where you hadn't granted nopasswd so it prompted, hung and timed out. You should also check out http://nagiosplug.sourceforge.net/developer-guidelines.html for the development guidelines. -h -- Hari Sekhon - This SF.net email is sponsored by: Microsoft Defy all challenges.

I had to raise the DEFAULT_TIMEOUT to something like 30 on some older machines to get this to work. But on newer system 10 seconds are ok. Matthias Yes it depends on what checks you run as well, getting the number of all available upgrades is very slow, hence why it's not the default - you'd need 30-40 seconds, but this is completely emerge's fault which has always been slow to start up. I find that increasing the --timeout helps anyway even if you just stick to the default Outstanding Security Packages check as it takes glsa-check around 6.5-7 seconds just to return the output of security packages, you may end up hitting the 10 second limit, and of course this will be slower on old machines... This is one good reason for the --timeout switch. I've just used that switch to increase the running timeout to 30 seconds as well just to be safe from timeouts. If you're referring to the DEFAULT_TIMEOUT in the plugin, it's not really needed to change the code if you use the --timeout switch when you run it (or embed that in the NRPE call or whatever you use for remote checks), but it's completely your choice. -h -- Hari Sekhon - This SF.net email is sponsored by: Microsoft Defy all challenges.
