[Nagios-users] check_udp error message

[Marco B. <m.b...@it...>]

Hi all

I need to control many UDP ports.

 

I run the command:

./check_udp –H <IP_ADDRESS> –p 88

 

I receive following error message (with state UNKNOWN) :

With UDP checks, a send/expect string must be specified

 

Can anyone help me to solve it?

Those parameters should be optional..

 

regards

Hi,

 

On the Host Groups Overview page - is it possible to custom arrange the
hostgroups displayed rather than by the default of alphabetically, by
editing some file?

 

Thanks

Maybe Nagios BPI will also work for you.

[Nagios-users] Ziproxy - Nagios check

[Paul S. <pau...@on...>]

Hello
Has anyone developed a check to confirm that Ziproxy (useful compression proxy) is running (under xinetd)?
I would like to use a standard plugin if possible, I have been playing with the 'check_http' but without success.

Paul

If i am not mistaken something like cacti would be good to monitor such
data in terms of the time period when there was the load etc.

[Nagios-users] Nagios Load Alerts

[Kaushal S. <kau...@gm...>]

Hi,

Is there a way to know what caused load issue on a specific time period.
For example lets say the load critical alert by nagios during night time
period. How do i debug? I know of top utility but not sure if it stores
historical data. Please suggest and any recommendations to optimize the
thresholds for Load service based on best practices.

Re: [Nagios-users] Is it possible to recieve a single global notification for all checks?

[Páll G. S. <pa...@ok...>]

I made something the other day that might help you.

check_nagios_services is a plugin that checks the current of other nagios services (via mk-livestatus) and you can set threshold, for example if one of many http checks are critical, return critical as well.

Maybe you can use that as a basis to solve your problem.

Your solution was to create a single check that at the same time performs various checks, similar to the check_multi . However I need each check to be an independent check :( Any other suggestion is appreciated.

[Nagios-users] About the global handler.

[Alex F. <afl...@gm...>]

Hello,

Iam trying to use a global handler so that it invokes a failover by 
distinguishing first if the host is CRITICAL, if its then it should 
failover all services under that host and ignore the number of services 
of that particular host in trouble and NOT try to failover specific 
services.

If specific services of that host are in trouble AND the host state is 
OK then it should failover only the specific services.

Is this something that can be achieved by a global host handler? If yes 
how? according to what i read i cannot pass specific service arguments 
to the global handler. It only gets fed the nagios macros so it cannot 
distinguish what action to take according to the circumstances.

[Nagios-users] Is it possible to recieve a single global notification for all checks?

[Alex F. <afl...@gm...>]

Hello Nginx,

I have a single host, and dozens of services of the same type (http 
check) monitored.

When a service goes down it is normal for others to report CRITICAL at 
the same time. Intead of generating a notification for each independant 
service can I have a SINGLE email consolidate the report on whats on 
CRITICAL?

Perhaps using a global handler, however how would this work with the 
part of one email per minute if my understanding is that the global 
event handler runs independtly for each service?

Anything creative is welcome.

[Nagios-users] check_openmanage whitelist feature request

[Prado, D. <dav...@ex...>]

Hello Trond,

First of all, I want to thank you for the excellent plugin and continued support and development.

The purpose of this is to suggest including a whitelist option to do the opposite of the blacklist option.
This will allow anyone to create checks with higher granularity.

For example, something like
# check_openmanage -s -H myhost --only storage --whitelist vdisk=0:1
would allow me to check status of an individual vdisk.

Thanks,

Yes, I did something similar recently where I wanted to check for existence
of an orphaned file only if ftp failed on another server.

The command definition looked like this:

define command {
  command_name check-for-orphan
  command_line   if $USER1$/check_ftp -H $ARG1$ $ARG2$ $USER10$ then
$USER1$/check_multi -s $HOSTADDRESS$ $ARG3$ $USER10$ else exit 0 $USER10$ fi
  register 1
}

Obviously you won't be using check_ftp and check_multi (probably check_snmp
or your own custom plugins instead) but hopefully you can see now how you
can do something similar to run the second check only if the first returns
an ok state (I'm presuming your first check will return an ok state if
running=1 and the second returns ok if temperature < 50 degrees).

Where you see $USER10$ here, that refers to a macro in your
/usr/local/nagios/etc/resource.cfg file that gives you a semi-colon like so:

$USER10$=;

It's a bit of a kludge to allow you to have a multi-line command in a
Nagios command definition.

Note that during the time that the first check returns a non-ok state, the
service check will be in an OK state (the exit 0) but will have null
output.  I guess you could put another line with echo "something" in there
if you want it to say something meaningful.

I hope that makes some sense...

By the way, please don't blame me if this method breaks in some future
version of Nagios - I'm using 3.3.1 on this one.

Cheers,

Jim

[Nagios-users] check snmp logic

[Mark C. <mc...@ps...>]

So I need to utilize some logic in my service checks.

I have a chiller that if it is not running the discharge temp is not of 
concern.  However if it is running the discharge temp needs to be lower 
than 50 degrees.

Is there a way to have the check snmp utilize some logic that says if 
running = 0 then ignore discharge temp.  If running = 1 then discharge 
temp must be <50 degrees?

THe other option I thought of was using dependencies.  Anyone have 
suggestions on that?

[Nagios-users] Webtransaction monitoring

[Watanabe, Y. <yu....@jp...>]

Hi all!

I would like to share ideas for web transaction monitoring for nagios.
I believe that there are couple of ways to implement this on nagios.

http://jon.netdork.net/2011/03/19/using-nagios-to-monitor-webpages/

We use check_website.pl because its simple.
What does everyone else use for this specific monitoring?

Thanks,

OK, yes, I grok that.  I guess I would want the collector to be *able*
to run checks, if it doesn't get timely information from the pollers.
I'm assuming that's why it's even trying in the first place - it
doesn't see a result in a timely manner, so it thinks it should run
one.

Which circles back to my original question - why can't it run the
check?  Why isn't it finding what it needs to find?  The workers
are running as the nagios user, and I don't see anything that appears
pertinent in the mod_gearman_worker.conf file...  What am I missing?
Neither the gearmand.log nor the mod_gearman_worker.log files seem
to have any complaints (but I haven't bumped up the debug on them yet).

Thanks so much for your help!

Benny

Well, i assumed it. You are the only one which really can tell that.
You will need a worker on each host which should run checks. If your
collector should not run any checks, than no worker is necessary.

See http://labs.consol.de/nagios/mod-gearman/#_common_scenarios for a list
of common setups.

Oh ho!  I have multiple *gearman* processes running:

ps axuwwwwww | grep gearman
gearmand  5662  0.7  0.1 404672  2496 ?        Ssl  Aug17 118:29

nagios    5712  0.0  0.0  38024   640 ?        Ss   Aug17   1:03
/usr/bin/mod_gearman_worker -d
--config=/etc/mod_gearman/mod_gearman_worker.conf
--pidfile=/var/mod_gearman/mod_gearman_worker.pid
nagios   25919  0.0  0.1 137492  3016 ?        S    07:38   0:00
/usr/bin/mod_gearman_worker -d
--config=/etc/mod_gearman/mod_gearman_worker.conf
--pidfile=/var/mod_gearman/mod_gearman_worker.pid

.. etc ..

Are you saying I just need gearmand running on the collector?  I'm
quite new to gearman, so I might have misunderstood which parts are
necessary where.  I can easily shut down the mod_gearman_worker
service, I just need to understand the consequences.

I assumed that this was a Nagios error - perhaps I just have my
gearman setup configured wrong.
