<p>i would like to start collecting data from centos environments, eg netwk traffic (openvz /proc/net/dev), cpu utilisation (container or HN), cpu temp (HN), fan speeds. i already have nagios monitoring them, but, i'm not aware that nagios offers data collection.</p>
<p>trusting you wouldn't suggest either a semi or a scooter to carry the groceries, what do y'all recommend? rrdtool? snmp? a control panel? other?</p>
