Nagios Support Forum

Does anyone now how to monitor the overall watts used by a switch and by port?

Thanks

If the device supports SNMP this would be the way. Otherwise, check to see if it has a web interface that reports this information, then it should be fairly simple to write a plugin that screen-scrapes this info.

I suspect if I could write plugins to scrape websites for Nagios I wouldn't be posting simple questions on this forum.

Then I would suggest sticking to SNMP. Easier in some ways, harder in others, but it all depends on whether or not your device supports SNMP and if it does, it would need to specifically have an OID for the power used on a port.
