Don't include Response Time from all the locations to the chart. Kindly just include the graph of concern location which is has an alerts, EXCEEDED on the threshold or DOWN.
Primary Location: Beijing - CHN
Monitor is in Trouble
Response time from Qingdao City - CHN exceeded 10000 ms.
so, the graph of
Qingdao City - CHN should be the one indicated on the Trouble Email Alert, not the graph of the primary location (Beijing - CHN) which is not the concern. Because its useless to indicate the graph of primary location on the report, since at the first place its not the one that exceeded. Unless if the alerts is coming from Beijing - CHN location.
I hope my example will help you to figure out my concern and it will deploy to the production soon.
