Nagios Support Forum

Ask for help! My email is [email protected].
I want to know why the field "Status information" showes "Return code of 255 is out of bounds" and the field "Status" showes "OK".
I check the nagios status file "status.dat" as follow:
servicestatus {
host_name=oracle_session_check
service_description=VOUCHER_1.114_db_session
modified_attributes=0
check_command=check_db_session!VOUCHER_1.114!vcquery!123456

Hope offer me your help! Thank U!

Interesting. It looks like you're using some sort of Oracle plugin? If so, which one?

Are you using check_nrpe or similar to help process these checks?

Finally, if you run the checks manually from the command line, do you get the same results? (OK Return code of 255 is out of bounds)

To jolson:

My detail info of the .cfg files as follow:

my service cfg:
define host{
use check_remote
host_name oracle_session_check
alias oracle session check
address 127.0.0.1
contact_groups admins
}

define service{
use generic-service
host_name oracle_session_check
check_interval 1800
retry_interval 10
contact_groups admins
service_description VOUCHER_1.114_db_session
check_command check_db_session!VOUCHER_1.114!vcquery!123456
}

command.cfg:
#check_db_session

define command{
command_name check_db_session
command_line check_db_session
command_line $USER1$/check_db_session.pl $ARG1$ $ARG2$ $ARG3$
}


resource.cfg:
$USER1$=/home/nagios/monitor/nagios/libexec

This is the output that I run the script mannually from the command line:
[nagios@a1a162 ~]$ /home/nagios/monitor/nagios/libexec/check_db_session.pl VOUCHER_1.114 vcquery 123456
****: HOST->a1a75.rh6.sh OS_USER->culws DB_USER->VOUCHER PRO->JDBCThinClient Normal[1] != 2

****: HOST->voucher-appweb OS_USER->voucher DB_USER->VOUCHER PRO->JDBCThinClient Normal[5] != 6
VOUCHER_1.114 OK!
------Check End.
[nagios@a1a162 ~]$ echo $?
0
[nagios@a1a162 ~]$ id
uid=500(nagios) gid=500(nagios) groups=500(nagios)
[nagios@a1a162 ~]$

Could you upload the check_db_session.pl script to this post so we can review it?

Hi, tgriep

Pls see the atachment.

Everything looks proper, my assumption is that these are not being set:

ORACLE_HOME
LD_LIBRARY_PATH

Check what they should be with the command below: Try adding them to the top of the perl script script under the use statements:

Thanks. Indeed, the "env" causes.

I just want to verify that if the issue resolved?

To tgriep:
Yes, my issue has been resolved.
Thanks!

I'll be closing this thread now, but feel free to open another if you need anything in the future!
