I'm looking into the possibility of installing an additional polling engine. We are nowhere near polling capacity, but we are thinking of setting one up as a remote polling engine at a customer location. For security reasons, the main polling engine cannot have direct connectivity to all of the monitored nodes. So we were looking at putting a remote polling engine in a DMZ that can poll locally and forward the data back across a WAN link to a central datacenter.
The only additional polling engine on the price list is for the SLX NPM license. And I don't see the additional polling engine as an option in my downloads. So does this mean I have to upgrade to SLX before I can add an additional polling engine? Or maybe I'm missing something
