Hi Mike,

Its Ray again! hope things are well.

I am having problems with my current Nagios configuration.

I am not sure what went wrong… when I type in check_cuda5 xxxx.xxx.xxxx.xxxx public in 10 30 it displays
IN Critical – 0 messages queued |MailINQueue=0;10;30root@CHILMELLX01:

I’ve checked the SNMP connection with SNMP tools – I cant figure out this issue! can you please help! does the newer barracuda firmware affect this script?

Thanks!

-Ray

In #4 where you defined the service check command, did you just leave out the SNMP community string so you wouldn’t disclose it, or is it actually not there in the service check definition. You will need a community string passed or the SNMP check won’t work.

The plugin really should catch this and not give you a OK result… I will try to take a look at that when I get a few minutes. But in the meantime if you resolve the lack of a community string that should resolve the issue. If you really do have a community string in there, then I would suggest running the command from the command line as the account nagios runs under and seeing what you get. Post results if that is the case and I will try to assist you.

thanks for the plugin…
Worked for me with the follows
1. put all “downloands” files (2 php) at /usr/local/nagios/libexec
2. change privilages on thoses 2 files for user nagios to read-write (and everyone!). Make sure that check_cuda5.php is executable.
3. gedit /usr/local/nagios/etc/objects/commands.cfg and put at the end :
define command {
command_name Check_Cuda_Queues
command_line $USER1$/check_cuda5 $HOSTADDRESS$ public $ARG1$ $ARG2$ $ARG3$
}
Note that i removed the .php.
4. gedit /usr/local/nagios/etc/objects/localhost.cfg and put
define host{
use linux-server ; Inherit default values from a template
host_name baracuda ; The name we’re giving to this host
alias baracuda ; A longer name associated with the host
address 10.10.10.3 ; IP address of the host
}

define service {
service_description Check Barracuda Outbound Mail Queue
use generic-service
host_name baracuda
check_command Check_Cuda_Queues!in!350!500
}

5. check if all is ok.
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

6. restart nagios.
The problem i have now is that
Current Status: OK
(No output returned from plugin)
Warning: snmpget(): No response from 10.10.10.3 in /usr/local/nagios/libexec/check_cuda5 on line 22
IN OK – 0 messages queued

is normal the No output returned.. but it’s says In OK -0 messages queed
(isn’t that an output)?

Top Plugin – works a treat
For Ubuntu, i needed to install php5-cli and php5-snmp, copy teh plugin to /usr/local/nagios/libexec and make sure that i define the plugin something like:

define command {
command_name Check_Cuda_Queues
command_line $USER1$/check_cuda.php $HOSTADDRESS$ public $ARG1$ $ARG2$ $ARG3$
}

make sure that it is check_cuda.php!
I can then call the check as:

define service {
service_description Check Barracuda Outbound Mail Queue
use generic-service
host_name Barracuda-In,Barracuda-Out
check_command Check_Cuda_Queues!in!350!500
}

I can confirm that this update does work on php5 and php5-snmp

Anyone that uses the barracuda and nagios must have this.

Thanks again Mike

Ray,

Sorry it took me a while to do this, but I did just actually test the script under PHP5. I don’t currently have access to Barracuda firewalls, so I could only replicate and resolve the issue you were seeing, not fully test. Strictly speaking the script SHOULD have worked under PHP5 without any modifications. But, I got the same results you did when I ran it from the command line under PHP5. After a bit of testing and experimentation all I basically did was create a new file with a working shebang line and a stupid little hello world to just confirm the shebang line was the source of the problem. Then I pasted in the other portion of the script without any other changes and I got the expected results. The download link in the post above now points to a new zip file with a new file called check_cuda5. Thanks for letting me know and being patient/persistent.

Mike
