[Nagios-users] ORACLE instance and CHECK_NRPE: No output returned from daemon

2006-04-04 Thread Sandeep Narasimha Murthy 
Hello,

My command is invoking a script which verifies the state of an Oracle instance. 
My problem is when I invoke this command, I get a 
CHECK_NRPE: No output returned from daemon   Error. The problem has to be with 
invoking this script because if I substitute the code in the script with just 
an echo, it works fine.

I tried implementing what I had posted below earlier on but it doesn't work in 
this case.

Any ideas/ suggestions ??

thanks

Hi again,

I solved the problem and thought I should share this here..

The reason I was getting an Unable to read Output error was because the output 
generated by the called script was not being deciphered by nagios. I had some 
java commands in the script and possibly Nagios couldn't invoke them..

I solved the issue by creating a new script which then invoked the main script 
and then read its contents back to nagios.

Subject: [Nagios-users] NRPE: Unable to read output Problems

Hi all,

I installed a new script in a remote server but on trying to invoke it
from my Nagios host with the command : 

./check_nrpesun -H 192.168.5.10  -p 5666 -t 5 -c check_wlheap

I get a "NRPE: Unable to read output " message.

Now, before anybody suggests that I check the file and directory
permissions, I have already done that and confirmed and reconfirmed that
the script has the proper permissions. :)

I have a number of scripts running on this remote server and all of them
run fine except for this one. All have the same permissions and are
configured Ok in the nrpe.cfg.

Is there anything else I should check for ?

TIA,

sg

Does the NRPE user have privileges to execute the script? Does
the script load all of its environmental dependencies (there is
no .profile loaded under NRPE)?

I would tend to second the 'check your environment variables' 
suggestion.  Oracle (and binaries linked to oracle, include DBI::Perl 
etc). usually requires at least the following env. vars set to function):


ORACLE_SID
ORACLE_HOME
LD_LIBRARY_PATH

Good luck,
David
