Need Help explaining to co-workers part of the Dashboard

Grafana setup to pull all info from Zabbix.

You will see a green back ground and that changes with status of server " Green, Amber, Red " we also have the Emoji setup for " thumbs up = Green, thumbs down = Amber, and the chocolate swirl for = Red "

  • Here is the issue the Blue Line. as you see this the status of the application has been the same for the last 6 hours. Now if activity starts to happen you will see a spike. I have tried to explain it that the spike represents 1.5 or 2. 1 = normal activity 1.5 = to some activity and 2 = multiple events. Where can I find the exact info that the blue line represents.
