I also couldnt make it work at first but some digging and I got it working - if you have any questions let me know.
Im trying to figure out the best Alerts to use for monitoring - I have setup a email alert based on Ping but i think an alert for the health of the producer would be prudent - my first idea was to do block producer blocknumber - adapools api block number then alert on a absolute value difference > X
Any suggestions on metrics to use without needing to install grafana meta queries and making it overly complicated?
