I have several UDPs configured to poll ServerTech PDUs. These have been up and working since March 2013. From some reason they have stopped updating the database. The last update was 10/27/2013. The transforms based on these pollers are working albiet based on data from 10/27/2013. I have tested the pollers in the UDP application and they respond correctly, they just don't poll from the NPM engine.
I have checked the logs (I think I checked the right ones) and can not find any errors nor any attempt to poll the devices. Any insights would by much appreciated.
Download and install HotFix 5 for NPM 10.6 from Customer Portal. It should fix your issue with custom pollers.
