Re: [Nagios-users] Check MS Terminal Services

[Hans Engelen]

The thread mentions one already :
 
WMI, though if you can not install anything at all on the server you will need 1 additional machine (on which you can install some soft, namely the soft from the url below) to act as a 'probe'
 
http://www.nagiosexchange.org/NRPE_Plugins.66.0.html?&tx_netnagext_pi1[p_view]=235
 
With these you set up one machine (wintel machine) as your gatherer of information, the machine uses WMI (which is standard on all Wintel boxes) to query the information you nee (see above) and forwards it to the Nagios machine via nrpe_nt. The need for this 1 wintel machine (the probe if you wish) arises from the fact that WMI is M$-only. No way to query it from a unix box afaik.

Re: [Nagios-users] How to automate availability reports monthly ?

[Hans Engelen]

There is a perl module for this, which seems to do the trick pretty good.
 
That being said it does take a bit of trial and error to get what you need perhaps.
 
The module in question is on CPAN under H/HO/HOPCROFTS/Nagios-Report-0.002.tar.gz (at the time of this mail).
 
Easiest way to get and install it is using the CPAN tool that comes with most distrubs these days :
 
~# perl -MCPAN -eshell
cpan> install Nagios::Report
 
Note that if you have never used this tool before you will get a bunch of configuration questions the first time. The options are well explained so this should be easy.
 
The only problem with this setup is if you have Nagios installed via the rpm's made by Dag. The paths are different and Nagios::Report uses the default paths to find the Nagios CGI applications from which it gets its info. (So it does not need a DB or somesuch).

 
There are also a number of examples that come with the package, those you can still find in the CPAN tools cache (~/.cpan usually). You could also recompile the module from there should you need to.
 
Cheers,
Hans

Re: [Nagios-users] How to report the number of RDP session on a W2K3 Terminal Server

[Hans Engelen]

Indeed thats a WMI Query you could use already.
 
The counters for perfmon are :
Terminal Services\Active Sessions
Terminal Services\Inactive Sessions
Terminal Services\Total Sessions
 
Which do not distinguish between RDP or ICA sessions I might add. So if you have say 2 admins logged in via RDP, 10 users logged in via ICA and 5 users logged in via ICA but disconnected your counters would respectivly be 12, 5 and 17.

 
At first glance I see no quick way however to split the 12 active sessions into two values (one for RDP and one for ICA sessions). Other then enumerating the actual sessions and doing the math on it in your check (which means you are as good as obligated to run something like a small _vbscript_ on your winbox and have it relay the result through nsca).

 
Maybe I am overlooking a way to sidestep this.

Hans

Re: [Nagios-users] Check_oracle

[Hans Engelen]

Hi,actually if you look inside the check_oracle script you will see that it is trying to determiing the oracle home based on whats in /etc/oratab or /opt/var/etcoratab (not sure about the last one, have to work from memory here). Failure to get a valid oracle_home from that it falls back to a default and hardcoded (in the check_oracle shell script) setting. I just cannot remember if it uses the oratab method even with an ORACLE_HOME already being defined.
Also you might want to check permissions on the tnsping binary and for that matter most of the other stuff installed by the oracle client setup. Possibly the nagios user (the one running the nagios process) does not have the right to execute the tnsping binary which, again if memory serves, leads to the, in this case misleading, no tns listener output. Much of all this depends on which client version you have installed. Everytime I install a new one I spend a lot of time figuring out silly little quirks and changes.

Re: [Nagios-users] Nagios-Report-0.002 on CPAN/NagiosExchange.

[Hans Engelen]

Hmm,
 
it would be a pitty not to develop this thing further. Like you say it provides the kind of reports management likes and up until now it is the only way I have found to create biased reporting.
 
What do I mean ? I mean I don't care about how many hours application or server xyz was down during the weekend. Those hours are of no importance to me in terms of management reports. The information and especially metrics outside of these hours need to be taken for administration purposes of course. But the weekend is used here for maintenance as is the case in many places. For my SLA's these hours should not be counted. Up until now your tool is the only tool I have found that can ignore data based on time-tables in its reports.

 
So as far as I am concerned please keep up the good work.
 
Question though .. DB NEB modules ?

Re: [Nagios-users] Monitor Fileserver

[Hans Engelen]

Dangit replied privately and not to the list, anyway heres a forward.Also just checked the /root/.smb/smb.conf reference is actually a workaround for a problem with samba's libsmbclient in the perl module Filesys::SmbClient (used by check_smb_shares.pl). Aparantly libsmbclient segfaults if it does not exist. Therefor if it does not exist the perl module Filesys::SmbClient tries to make one (an empty one) but has no permission to do so from what you wrote. I supose you could make it yourself (touch /root/.smb/smb.conf; chmod og+r /root/.smb/smb.conf). Maybe that will solve your issues with that particular check allowing you to use it to monitor the remote shares you spoke of

For mapped drives that is quite normal since mapped drives are, barring a small number of special cases, only accessible for the user that did the actual mapping. It's the same problem you get for other NT services trying to access a drive mapping made from another user. Also most likely your pNSClient (or NC_Net or NSClient++) or whatever agent you have running on the Windows box is running under the System security setting. This security context is only valid for that windows box internally and as such has no credentials to access anything beyond that machine. This includes (but is not limited to) shares. 
Theoretically you could of course run your Nagios Agent under an actual user account, log in interactively on that same account and create a persistent mapping (net use * \\server\share /persist:yes, if memory serves) to the shares in question. Since the service will use the same profile when logging in that should solve the issue. But why even monitor a remote disk in this way. Just install the Nagios Agent on the server that houses the share and monitor it directly instead of indirectly (with all the quirks and pitfalls that come with it).
Of course in this case the check_smb_shares is a solution too. As to why it insists on writing to /root/.smb/smb.conf is a bit strange. Possibly this was defined somewhere in the check_smb_shares.pl file. Open it up in a text editor and see.

Re: [Nagios-users] Nagios VM Player?

[Hans Engelen]

I have to agree with Brian here.
 
The timedrift issue is present on VMware too. There are a fair number of documents on the matter on the VMware site and it is a major showstopper indeed. Possibly they will get this fixed and sorted out someday but I don't think they are quite there yet. The latency issue is a problem too on vmware. That being said the VMware player is a good way of demonstrating a Nagios setup. It just is not a good production/permanent solution. 
 
I am not sure I understand where your problem lies though. I am guessing it lies with the installation of the OS and Nagios & Co by non-linux-familiars. A better choice in this case might be to prepare a fully setup image that has everything presetup for them. Something along the lines of a Ghost image maybe. Maybe even a live-cd that keeps it's configs on say a USB-stick (a old 32mb stick would be more then enough) or even a floppy disk (if theres not too much to monitor). The latter would even make it really easy for you to send them updates. Just prepare a new Live-CD with the latest Nagios/Plugins/Graphical Nagios Config tools and they would be all sorted out. You could even go sofar as to actually make the whole Linux/Nagios install live on a USB stick of 128 or 256 mb. Most recent machines can boot from USB sticks too now and I have one like it for whenever I want to boot my PC at work into a linux OS. This way you could have them use a cheap diskless machine even which could run extremely silently.

 
As you can see, plenty of options that don't have to cost much at all. VMware is nice in that way that it does complete hardware abstraction but it's not that much of a problem anyway on Linux. Most hardware is automatically detected and setup already and the few things that are not can easily be reconfigured. In fact on live-cd's like Knoppix and DamnSmallLinux even that is done automatically (think of the X server config).

 
Come to think about it, EchelonLinux (based on DamnSmallLinux) already has Nagios on-board as a live-cd (along with a few other network tools). It might not be exactly what you need but would probably be a good start with minimal modification needed to suit your goal.

Re: [Nagios-users] Nagios VM Player?

[Hans Engelen]

Hehe,
 
shoulda googled some before I replied, heres an even better idea maybe. Live-CD too, complete with a nagios config tool (nag2web) to configure nagios via webpages. Iso to be had here : 
http://nag2web.de/index.php?page=85 .. they are making VMware images soon too they say so :). Only thing is it seems to be german in origina and I have tested it yet to see if there is an english set too. Still it shows exactly what I meant.

Re: [Nagios-users] Question: is there any interest in a WMI client for Linux?

[Hans Engelen]

Well in terms of need, I have (and I am sure there are others, seen messages to that effect pass the mailing lists on a regular basis) a defenite need to also monitor more then WMI provides and for that matter check_nt does not have either. I am sure there are many such things but these are high on my list right now :
- Monitor file sizes (got a couple of processes that dare write transaction logs that sometimes go up to 2 GB in a matter of days at which point the 2 GB filesize problem on Windows causes the application to die a horrible death)
- Monitor Directory Sizes (not so much for me but saw that pass by on the list a few days ago)- File Age (nc_net has this) to detect hanging processes for example.- Log parser with a read-mark (so it only reads new lines since last check). Mind you not clear on how to work this into Nagios. I mean, I would want to have nagios monitor a log file for say an error like 'ORA-x no active database connection' (or whatever the exact error is) and raise an alert at that point. What I am not sure about is how to then let Nagios know the error has been fixed. I suppose I coul parse the whole log every time and archive logs when I restart the process at which point the ORA-x would no longer be present in the log but the problem is these logs are huge and would probably constitute a huge performance hit if read completely on a regular basis. It's a tricky one.
Either way unless I am mistaken these things are not easily done in WMI if they are even possible at all. But there is no denying that WMI gives you access to a wealth of information. It will be interesting to see how you do it though. Securitywise it seems like a challenge for sure.  And performance wise it is not easy either. Count me in though if you want it tested.

Re: [Nagios-users] I have a problem!!! Help

[Hans Engelen]

I have to go with Thomas here, my money is on SElinux. I had the worst time with that on my RHEL4 setup. The premature end of headers error had me fooled for ages back then. My suggestion is, at least so you can verify and test, to turn off SElinux temporarily and see what that gives.
I am almost convinced you will find that has solved the issue. If you want to check if SELinux is enabled run 'getenforce'. This will tell you if it is. To set it to permissive (to disable it completely you need to modify /etc/grub.conf or /etc/selinux/config) temporarily use 'setenforce 0'. Please note however this is only temporary and will not survive a reboot. If memory serves there is an audit log for SELinux somewhere too but since I do not use SELinux I must admit I am not sure where exactly that lives. I believe the tool 'seaudit' allows you to examine the log too and even gives you a peek on the policy enforced. My apologies if my explanation is not more descriptive. I decided long ago that SELinux was not something I was willing to endure on my systems since they are used too extensivly for testing purposes and SELinux slowed me down way too much.
Hope it helps,Cheers.On 2/13/06, [EMAIL PROTECTED] <

Re: [Nagios-users] check_mem giving wrong values

[Hans Engelen]

Seems correct to me or am I missing the point.
Mind you  the 11 % is not counting what is used up for buffers and cache.
So if you look at the second line of your result from free you will see 54168 used which is your 11 % (before some hefty rounding). Note that the first line of free gives you the amount of mem used for caching and buffers on top of what applications use to come to a grand total of 253588 mem used. I am guessing thats the value you are looking at and thats what got you confused.
