Question posted in 
I have one virtual server running on centos7. I configure it for the Nagios monitoring tool. I created the config file etc. I have 9 DB instances. When I migrated the DB config file with Nagios(adding to the Nagios )
I saw this error code on http://mysiteipaddr/nagios
CRITICAL – cannot connect to db.ipaddress.com. install_driver(DB2) failed: Can’t locate DBD/DB2.pm in @INC (@INC contains: /usr/local/nagios/libexec /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at (eval 10) line 3.
After this error, I realize the DB2 is not installed on my machine. I’ve installed the DB2 drivers and when I execute this command I’m facing this output.
db2ls

But when I want to execute DB2 command like db2start, db2stop, db2status, it won’t execute and I got this error code.
bash: db2stop: command not found
bash: db2start:command not found

Do you have an instance created? run /opt/ibm/db2/V9.7/instance/db2ilist
Please check the folder /home/tobe/sqllib/adm for db2start and db2stop commands. You can also define an alias if you want to call them directly.
Install below package in all of the instances:
yum -y install perl-CPANhope so this will be helpful for you….!!!!
