From some time now we have started using a “monitoring distribution”.
It uses passive monitoring where it can be used, and has lots of plugins for standard services.
It gives you a nice output, check it out:

All you need to know is here => http://omdistro.org/
To install the FULL pack you just need to do the following:
# where to start => http://omdistro.org/
rpm -ivh epel-release-6-8.noarch.rpm
rpm -Uvh "https://labs.consol.de/repo/stable/rhel6/x86_64/labs-consol-stable.rhel6.noarch.rpm"
yum install omd-1.10
omd create monit
yum install check-mk-agent
omd create lab
After this, you can go to your server http://server/monit/ with user omdadmin and password omd , and you will find yourself adding machines to the monitoring.
The agents can be found on the server itself, at the /opt/omd/sites/monit/share/agents/ directory (I may misspell but is arround that )
