Hi again!

These are my configurations for both servers (server2 and working server):
Working Server:

submit_service_check

Code: Select all

#!/bin/sh
# Arguments:
#  $1 = host_name (Short name of host that the service is
#       associated with)
#  $2 = svc_description (Description of the service)
#  $3 = return_code (An integer that determines the state
#       of the service check, 0=OK, 1=WARNING, 2=CRITICAL,
#       3=UNKNOWN).
#  $4 = plugin_output (A text string that should be used
#       as the plugin output for the service check)
#
#  $5 = $LONGSERVICEOUTPUT$
#  $6 = $SERVICESTATETYPE$ (= SOFT ou HARD)
#  $7 = $SERVICEPERFDATA$

# Convert the state string to the corresponding return code
	return_code=-1
	myfirst=`expr substr "$4" 1 1`

	case "$3" in
    	    OK)

        }
Forgive me for dumping all the information in here but these are the configurations I have for both Server2 and the working server.
Do you see any difference because I can't. I know I'm missing something but I am completely lost in here.

EDIT: I realized just now that the versions of the check_nrpe is different in both servers. Do you think that this might be the reason why the plugin_output is filled with all information in one server and in the other is not?
Thank you

What are the version of check_nrpe that are running on each server?
Also what is the version of send_nsca on each server and could you post the send_nsca.cfg file for each server?

Hello again!

The information you asked is below:

Working server:

send_nsca version

send_nsca.cfg

Code: Select all

# ENCRYPTION PASSWORD
# This is the password/passphrase that should be used to encrypt the
# outgoing packets.  Note that the nsca daemon must use the same
# password when decrypting the packet!
# IMPORTANT: You don't want all the users on this system to be able

# restrictive permissions on this config file!
#
password=password


# ENCRYPTION METHOD

#       decryption method the nsca daemon uses (as specified in
#       the nsca.cfg file)!!
# Values:
#       0 = None        (Do NOT use this option)

Code: Select all

../libexec/check_nrpe -H IP_ADDRESS
I (0,4,1,102 2013-07-15) seem to be doing fine...
I even included the NSClient version for both Backup Servers (the service check is about checking the backups in a Backup Server, as I written in the initial post), which is the only difference I found.
Anyway I concatenated the output and the long_output in the server2's submit_service_check file and I am getting all the information now, but I still don't understand why in the other server I didn't have to.
Thanks

You are using 2 different versions of NSClient++ and it has been known to have bugs in newer versions...

FYI, if you receive NSCA checks from NSClient++ 0.3.9 and below you MUST use NSCA version 2.7.2. Newer versions of NSCA are not friendly with the old version of NSClient++ 0.3.9.

Can you run this command on both servers please and post the output of the versions:

Code: Select all

/usr/local/nagios/bin/nsca --help

Sorry for taking so long.
I believe I have showed in the previous posts the version of nsca for both servers and it's the same for both: 2.7.2.

Thank you

Can you install the same version version of NSClient++ on the failing server that is running on the working server and see if that fixes it?

Hello!

No I can't install but I now comprehend that the issue is in the NSClient version.
Anyway I got a workaround by concatenating the output and the longoutput. It's working.
Thank you for all the patience and help.

Best regards
