Speaking on Deep Background, the Press Secretary whispered:
Question: We are looking for something that sits in the PDUs or branch circuit-breaker distribution load centers, that, on a branch-circuit by branch-circuit basis, can monitor amperage, and be queried by SNMP.
Considering there are several hundreds of circuits to be monitored, cheap and featureless (all we need is amperage via SNMP) is fine.
You really want wattage. The power factor of switched supplies is far from unity. Take a look at <http://www.quadlogic.com/transmeter1.html> Also, recall you sell each watt twice -- once to heat up a chassis, and a 2nd time for the HVAC to cool it. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
