PI PerfMon interface to support ArcReplace
Right now PerfMon only supports ArcNoReplace. PerfMon has a history of failing over if a server is unreachable. And since PerfMon only supports Hot failover, every time it fails over the new interface tries to write values that the old one already wrote. I would like to be able to specify ArcNoReplace so I don't get an error flood every time the interface fails over.
