I want to know how to have the ZD3K send an alert within 5 minutes of any 7372 or R500 going disconnected.
We have tested the email setup, and get test messages. Just cannot find where to set the delay timer for alerts on disconnect.

Thanks

The ZoneDirector does not consider an AP to be Disconnected for 20 minutes before sending email alerts.
We exchange heartbeats between AP/ZD, and have programmed recovery attempts into the equation, before deciding they are truely "disconnected".

The details, from KBA-1658: What does the "heartbeat lost" message indicate?

ZoneDirector (ZD)  and connected Access Points (AP) expect heartbeat (echo) requests or responses in 40 and 30 seconds respectively. If not ZD and AP would consider the heartbeat is lost.

ZD side

a.       After 2 consecutive (80 seconds) heartbeat losses, ZD raises a "heartbeat lost" alert and deletes the AP.

b.      After another 20 minutes, if the AP does not discover and join ZD, ZD raises "Lost contact to AP" alert.

AP side

c.       After a heartbeat lost (30 seconds),  AP sends 12 consecutive heartbeat requests every 5 seconds (total 60 seconds).  If it still does not hear a response from ZD, AP enters Sole Run state and starts to send discovery request.

d.      In Sole Run state, AP sends out discovery request every 5 seconds for 15 minutes.  After receiving no responses, AP will reboot and leave a reboot reason viewable in support text stating "cannot discover ZD in 180 attempts".

Thank you! Very helpful. I'd love to see a waterfall chart that details each step for AP->ZD registration, as well as the heartbeats and what happens when those are lost. Having some kind of waterfall/flow chart would be immensely helpful. Maybe I should make one. All the information is scattered around, but there's no single source for troubleshooting AP registration in-depth.

You're welcome Nick, and you can probably see the AP state changes in a ZD debug log, if you choose Access Points under debug components and track a single AP's MAC as you reboot it. Compare with what's seen in that AP's support info log section.  If you make a chart, please share!

I could try, but it would be great to get an official doc from Ruckus that was approved by engineering :)

Looks correct to me.
