I’ve added a distributed poller to my existing single server installation. The distributed poller seems to be connecting to the database and memcached on the main server just fine. When running poller-wrapper.py on each server at the same time, the new poller doesn’t poll any devices and the main server only polls a very small portion of devices, of which the total amount changes each interval. I currently have 500 devices added that should be getting polled.
