CA APM - WebView console graph with top 100

    ​Hi community,

    Within a configuration of a dashboard graph, found something interesting.  If you use top N, let say 100, and the metric grouping has hundreds of metrics, the graph refreshes every 15 seconds and the displayed lines within the graph, when set to Live (8 minute) will only display based on the top 100 within the current 15 second window.

    How does this behave?
    Let say you have 500 metrics and one of the top 100, varies in value enough to be within the top 100 one cycle, and not within the top 100 the next.  So if you are viewing the graph, the varying value line, will disappear and may reappear if it returns into the top 100. 

    Our end users started calling on why they got called but the live graph does not show the line that triggered the alert.  Also in historic mode, the top 100 is computed on the last metric cycle and not across the time frame.  In addition, if you set min/max, this is only for live display since historic display will ignore the min/max settings.

    Not seeing how useful using the top value filter can be if the graph is only for the current 15 second metric window.

    Hope this helps,
