Nagios + memory usage + SNMP

[Leandro @GuiadoPC]

Dear,

I'm using Nagios for a short time and I need to understand one thing
about snmp + nagios. Before I was using Cacti and could monitor the
memory usage on the hosts without having to install anything on it.
Picked up the information via SNMP. In Nagios, so I'm looking to monitor
memory usage and some other services I have to install the NRPE + xinetd
hosts. There is another option to monitrar these services without having
to install anything on remote hosts (being in the same network as the
server)?

thank you

Leandro Ferreira
