Nagios can use a flat file based backend or a db backend (in this case MySQL). If you use the MySQL backend you have to use a different script to check the state of Nagios. It is a perl script provided by nagios-plugins called check_nagios_db.pl located at two locations : /usr/nagios/libexec/check_nagios_db.pl /usr/nagios/libexec/contrib/check_nagios_db.pl Unfortunatly, it has two missing running dependencies that it requires to be able to execute itself. It is dev-perl/DBI and dev-perl/DBD-mysql. After emerging these two perl libs it is able to run without problems. *** Warning *** The stable dev-perl/DBD-mysql (2.9003) cannot compile with >=mysql-4.1.3. See 56356 for more detail but it has been fixed upstream with 2.9004 and available in portage in the unstable branch. Reproducible: Always Steps to Reproduce: 1. # emerge nagios 2.
