NagiosXI install_driver(DB2) failed

[paulol]

I have install the check_db2_health from the site http://labs.consol.de/lang/en/nagios/check_db2_health/
For that, I first install the dsdriver (v9.5)
then Perl-Module DBD::DBI (v1.632) installation via perl -MCPAN -e 'install DBI'
and finally PERL DBD::DB2 (v1.85) manual installation (Download the latest DBD::DB2 driver source from http://search.cpan.org/~ibmtordb2/)

I have installed that on the nagios xi server
On this server, the command line works fine :
as root or as the user "nagios" :

/usr/local/nagios/libexec/check_db2_health --hostname X.X.X.X --port XXXXX --username XXXXX --password XXXXXX --mode last-backup --database XXXXXX
CRITICAL - last backup of db XXXXXX was 8.90 days ago | last_backup=8.90;1;2

But, when this action is launch by NagiosXI, the result is :

install_driver(DB2) failed: Can't load '/usr/local/lib64/perl5/auto/DBD/DB2/DB2.so' for module DBD::DB2: libdb2.so.1: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 200.

The files "/usr/local/lib64/perl5/auto/DBD/DB2/DB2.so" exists on nagios xi server

If you want to test better i sent a script to test connection on DB2 via perl.

Env:
Linux CentOS 6.6 - 64bits
Nagios XI Manual Installation.

Do any of the parameters ($ARGn$s, etc) use illegal meta characters like !, $, ^, etc?

[paulol]

Nope.

Example:

/usr/local/nagios/libexec/check_db2_health --hostname X.X.X.X --port 50000 --username nagios --password nagios --mode last-backup --database dbpd07

[lmiltchev]

Can you run the following command to show us the plugin's usage?

Code: Select all

/usr/local/nagios/libexec/check_db2_health -h

Note: Not sure if I have the same version of the plugin on my testbox, but this is the usage I see:

Usage:
check_db2_health [-v] [-t <timeout>] --hostname <dbhost> --port <dbport,def: 50000>
--username=<username> --password=<password> --mode=<mode>
--database=<database>
check_db2_health [-h | --help]
check_db2_health [-V | --version]

Can you try the following?

Code: Select all

/usr/local/nagios/libexec/check_db2_health --hostname X.X.X.X --port 50000 --username=nagios --password=nagios --mode=last-backup --database=dbpd07

[paulol]

Code: Select all

./check_db2_health -version

Could you post the contents of the service check you are using in XI?

[cmerchant]

For the check_db2_health that you tried from XI, try not using the Test Check Command. Could you save the check, and apply config and go into Home --> services, (select your check, and perform an schedule a forced immediate check). Test Check should be used for simple checks that don't involve dynamic libraries that might not be set up in apache, unless you want to mess with httpd.conf and setenv LD_LIBRARY_PATH.

I will include some reference links to monitoring DB2 with nagios: (some dated but relevant)

This one I found by doing a search on your error message:

cmerchant,

I have working with nagios core for 5 years. Now i'm migrating to nagios xi. In the nagios core this check "check_db2_health" works fine. But in the Nagios XI does not, i dont know why.

Nagios Core - Debian Squeeze
Nagios XI - Centos 6.6

Following
nagios core cgi image ( This works.)
nagios xi cgi image (does not works)
Apache conf http. (Apacheconf from Nagios XI server)

[slansing]

Have you made sure that you have the DBD::DB2 module installed properl? As mentioned here:

https://labs.consol.de/nagios/check_db2_health/

That is a pre-requisite, though you mentioned you had gone through that step, can you double-check?
