Alerting for MPE and APE Question

We had an issue yesterday with our APE engine that caused it to freeze up and we had to give it a reboot for it to come back. We found out that there were 7 nodes that could not fully contact the APE and these 7 nodes keep reaching out and could not fully connect and it caused the APE to stop functioning. I have both the MPE and APE SAM applied to both nodes and am setting up an alert for both of these. I am a little rusty with alerting so hoping someone can check my logic here to make sure it is sane.

Whats the polling frequency of the SAM application applied to the engine? If it's 300s, I'd set that alert to must exist for 6 minutes so to allow for 2 polls to occure before alert trigger.

The alert looks good. The only thing you could change is removing the slightly redundant OR statements in the scope - see below. I agree with @sum_giais about the duration. I tend to see the occasional missed poll or status unknown for a component on occasion and the extended timing would force the status alert to wait for persistence.
