We have an open ticket on this, but I wanted to touch base with the community as well. We have NPM with an additional poller. APM is running on the server with NPM and it works fine. However, any device that is polled by the additional poller cannot be monitored correctly with APM. We have installed an instance of APM on the additional poller. Some of the troubleshooting has had us verify connectivity between the two pollers, repair Job Scheduler on the Primary and Job Engine and Orion Module Engine on both pollers. Nothing has worked yet. Maybe somebody out there can lead me in the right direction. Thanks.
