I was running some tests on the NPM where I shut down a device and would wait for the alert.
My polling times for alerts is 1 minute
It took 11 minutes after shut down to receive the alert.
When I turned the device back on, in the events it shows that the device has been turned on, but on the Node summary page, the device is still showing as down (it has been ~ 27 minutes). I tried re-polling and re-discovering, but the node still shows down. I cant seem to figure out why NPM is taking so long to update the node status.
I went over the settings, polling is set for 120 seconds, while all the alerts are set for 1 minute.
