We currently have a watch that sends an alert if a heartbeat in our logs goes down. We use two time periods to figure out whether any heartbeats within the last X period did not appear in the last Y period where Y < X.
We have an ask to create a visualization as part of an operational dashboard where there could be green/red tiles that show whether a connection is up/down. I've looked through the Kibana documentation and googled but haven't been able to find an answer.
