Hi,

I created a Alert Event, which searches for specific Text in “message”, last 1h every 1h. No aggregation done. I also set “Message Backlog” to 1, with the intention that it will send only 1 Alert for that timeframe. Notification I linked just sends Email with Description.

However, it seems that this is sending a lot more than 1 message every run.

Am I missing something?  
How do I configure so that only 1 message is sent in the interval?

Thanks
