Added servers to Nagios

Added some new fresh servers to nagios:

cd /usr/local/share/nagios/etc/servers

Add host-file to that directory. In host-file add services:

http

Edit following files (add new hosts):

/usr/local/share/nagios/etc/hostgroups.cfg (add server to hostgroup / VMWare group / )
/usr/local/share/nagios/etc/hostextinfo.cfg
/etc/n2rrd/templates/maps/service_name_maps

Installed snmp and nrpe on servers to check additional services:

yum install net-snmp.x86_64
service snmpd start
chkconfig --level 2345 snmpd on
yum install nagios-nrpe
service nrpe start
chkconfig --level 2345 nrpe on

edit firewall settings.

edit /etc/snmp/snmpd.conf : see example on other servers. Basically allow DMZ to access snmp views to monitor the system.
