Nagios Support Forum

Hello,

I have installed check_oracle_tbs plugin in my server Nagios, and I defined new command to check autoextend tablespaces:


define command{
command_name check_oracle_tbs
command_line $USER1$/check_oracle_tbs -SID=$ARG1$ -dbuser=$ARG2$ -dbpassword=$ARG3$ -w=$ARG4$ -c=$ARG5$ -wauto=$ARG6$
}

And I defined new service:

#Service definition
define service{
use Servicios-BBDD
host_name host
service_description Tablespace_Autoextend
max_check_attempts 2
normal_check_interval 10
retry_check_interval 3
notification_options c,r
check_period ORATEST
notification_period ORATEST
check_command check_oracle_tbs!inst!usu!pwd!80!90!80
}

But when I monitoring this, appear "no data" message. But i executed this, from Nagios Server in command line:

OK: remaining free space = 14619.44Mb

Monica

This usually has to do with ORACLE environment variables for the nagios user.

When you run it from the commandline you are likely using root as the user, however when Nagios runs it it is running as the nagios user.

You can simulate this by running Usually if you add your ORACLE environment variables to the nagios user it should work

Hello,

If i executed command:

su nagios -c '/usr/local/nagios/libexec/check_oracle_tbs -SID=inst -dbuser=usu -dbpassword=pwd -w=80 -c=90 -wauto=80'

appear this error:

install_driver(Oracle) failed: Can't load '/usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.5/i386-linux-thread-multi/DynaLoader.pm line 230.

But If I logged with nagios user, appear this error:

DBI connect('=inst','usu',...) failed: ORA-12154: TNS:could not resolve the connect identifier specified (DBD ERROR: OCIServerAttach) at /usr/local/nagios/libexec/check_oracle_tbs line 102
CRITICAL: ORA-12154: TNS:could not resolve the connect identifier specified (DBD ERROR: OCIServerAttach)

I try, executed, command with nagios user, it's correctly:

OK: remaining free space = 14617.88Mb

In .profile Nagios user, I add:

export LD_LIBRARY_PATH=/usr/lib/oracle/10.2.0.5/client/lib:/home/oracle/client10.2.0/lib

Regards,

To be clear, does this mean it is working correctly after you added the LD_LIBRARY_PATH ?

Hello,

I added LD_LIBRARY_PATH, but indicated errors are occurring after adding entry in .profile nagios user in server. Have I add anything in monitoring agent?

Regards.

I believe this needs to be added to
/home/nagios/.bashrc

Hello,

I add line in the file and executed command again, baut the result is the same.

Regards.

Can you compare to

Hello,

I modified check_oracle_tbs, because libexec directoty is not correctly:

use lib "/tools/home/capmau/libexec";

and i add:

$ENV{TNS_ADMIN} = '/home/oracle/client10.2.0/network/admin';

$ENV{LD_LIBRARY_PATH} = '/usr/lib/oracle/10.2.0.5/client/lib:/home/oracle/client10.2.0/lib';

If I executed, from line command:

su - capmau -c '/tools/home/capmau/libexec/check_oracle_tbs -SID=sid -dbuser=user -dbpassword=pwd -w=80 -c=90 -wauto=80
OK: remaining free space = 14611.12M

Have I modify anymore in check_oracle_tbs?

Regards.
