If the host is Linux/UNIX you could install NRPE on the monitored host, then use check_nrpe to remotely run the check_cpu plugin.

If the host is windows, you could install NC_Net on the monitored host, then use check_nt to query the CPU usage.

If the host is SNMP-capable, you could use check_snmp to query the CPU OID , either 1.3.6.1.4.1.2021.11.11.0 (NET-SNMP) or 1.3.6.1.4.1.9.2.1.58.0 (HOST-MIB)

If the host is a VMware guest, then you need to query the VirtualCentre. Check on monitoringexchange.org for the check_vmware plugin.

This will allow Nagios to alert based on CPU usage thresholds. To obtain graphs and so on (as in Ganglia) you will need to add something like pnp4nagios to graph the perfstats.
