Shouldn't Orion NPM send an email notification when a node recovers from being down?
Yes, if you have a Reset Action defined for the node down alert.
p.s: you may want to move your query to the Network Performance Monitor forum
Thanks - I found the reset action finally.
I was expecting it to be available from the web console but had to the 'Advanced Alert Manager' from the server instead.
I was running NPM from the Engineer's toolset previously and I guess I'm still getting used to the Orion interface.
Alert Management has moved to the web console in NPM v11.5 which was released yesterday
