I redid the ./configure command to match my CentOS environment for Nagios
2.10
./configure --prefix=/usr/local/nagios/
and then redid the aformentioned command lines in the service definitions to
match the path to the new perl scripts. Then I went back in my checks in
NagiosQL and checked the "performance data" box.
I'm assuming all I have to do now is just let the rrd files generate
themselves now?
(I ran an 'ls' in the /usr/local/nagios/share/perfdata folder, but no
folders by the same of hostnames, like I'm expecting)
