Create an alert that tells us when any client report a "non-latest" metric in the dashboard

Hello,

We have a custom metric reporting whether or not the metrics we are seeing are running or not. Its a simple panel that will read, “Latest Metrics” when the application we are monitoring is running, and “Non-latest Metrics” for when the application is down. We want a report to both notify us and Email us when this panel flips from “Latest Metric” to “Non-Latest Metric.” I am not very experienced with Grafana, so any help or advice would be extremely helpful.
