NagiosXI upgraded from 5.4.13 to 5.5.2 Oracle critical alert

[jfoshier]

After performing this in-place upgrade we received crtitial alerts on all of our Oracle hosts:

CRITICAL - cannot connect to mgmt1.ia.wd.org:1521/mgmt1.ia.wd.org. install_driver(Oracle) failed: Can't load '/usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.12.1: cannot open shared object file: No such file or dire

Did you use the "default" oracle commands or custom ones? The reason I am asking you is because it is possible that the "default" commands got overwritten on the upgrade, and your LD_LIBRARY_PATH and ORACLE_HOME environment variables are wrong. Maybe the client version (in the commands) changed from 12.1 to 11.2...

Can you go to the CCM > Commands, type oracle in the search bar, hit "Enter", and show us a screenshot of the page?
