The Application Insights tracker, allows to track the response information from the liveness pulses as custom events in Application Insights with this information:
Part of the info we store in Application Insights is the response time in milliseconds for each of the pulses tracked as a metric for the event, with this information, and the new Metrics (preview) blade in Azure Portal, you can create your own charts to track slow response from pulses over time, just create a new metric from the pulse information, with the average time, split by the name of the pulse, which is also part of the information stored in the custom event:
This charts can be pinned on your Azure Dashboards also.
One last way to explode this information is via Application Insights Analytics, which allows to query information on application Insights and create graphics based on this analytics queries, like this one which shows average response time for each pulse per day, in the last two days.
