PRTG Manual: HTTP History
To open the HTTP history view select a HTTP monitor in the HTTP monitor list and open 'HTTP History' in the monitors context menu.
The HTTP history form contains a graph with the response time of the HTTP request in milliseconds based on the time the request was made.
Below the graph is a grid containing the HTTP requests with their collected monitor results. The grid is grouped by the request name.
The following details are available for each entry in the grid
The time the request was made.
Indicates whether the HTTP request was successful.
The round trip time of the HTTP response in milliseconds.
By default the history view will update as new monitor results are collected, providing a real-time view of the monitor results. If you would like to stop the refresh of the view to inspect the current results, un-check the "Show Latest State" check box.
