Alert rule blackbox exporter ( probe_http_status_code)

Hi team,
I’m currently installing to learn how to warn about an app when down/up less than 10 minutes on grafana.
I have filebeat installed, kafka +ELK - http://xxxx:5601 is the application I need to install the alert for.
I installed prometheus, Grafana, Blackbox exporter.
Goal: when stop/start http://xxxx:5601 will show warning on grafana. Here I have installed all OK, dashboard probe_http_status_code has value 200. I want to set alert for it, but not installed yet.
Please help me, if you have a link, please send it to me, thanks



I found the article very good, exactly what I wanted. Unfortunately, Configure alerts in grafana is not available
