Playing with analytics - Exceptions by page

Its easy to join tables such as pageViews and exceptions, which will show the amount of exceptions that have occured, on a certain page view, which means you can focus efforts to reduce the amount of unhandled exceptions on pages which get more traffic

| join kind=leftouter (
    | where timestamp > ago(1d)
) on operation_Id
| where success == "False"
| summarize exceptionCount=count() by tostring(parseurl(url)["Path"])
| order by exceptionCount desc
