It would be great if there was functionality added to alerts in NPM that would allow you to prevent a node from re-triggering based on a condition. For instance if you don't want it to alert more than a certain amount in a given time frame. It is possible to work around this ish by setting a reset condition that requires a certain amount of system up time. Because of the way Orion alerts work they won't fire until they have been reset. This however is kind of clunky and requires an alert to stay active during the "waiting" period. It's also really limiting in the logic that you can use.
