Dependency vs notification timers

Votes:

0

In the process of standardizing my notification times, I noticed that I have multiple objects that have the same notification times as the sensor they are dependent upon. Is there an order of operations in how the dependency would trigger versus a notification being sent?

So, if my router goes down and this simultaneously causes me to lose connection to my dependent server and they're both set to trigger at 300 seconds, what happens first? Would the dependency trigger, where I would only receive a notification about the router, or would the notification trigger, where I would get a notice about both server and router?

Hello,

Assuming you have a device "server" witch is dependent on a device "router":

1) Ping is failing for both devices simultaneously.
2) As the ping for "router" failed, the "server" will be paused immediately. As long as a device is paused, the notifications for this device won't be send.
3) If the ping for "router" is still not working after 300 seconds, a notification will be send.
4) As soon as the "router" is reachable again, the device "server" will be resumed again.

So you would only get a notification for the downtime of the router in this case. Does this answer your question?

Kind Regards,
