System Metrics

If Metrics are enabled (see Metrics Settings) then the Request Metrics page will display various statistics about this server. These metrics are split into several sections:

 

Graphs

Here you can see 6 graphs: Request Load, Request Time, JDBC Load, JDBC Request Time, Memory Demand, and CPU. Click on any graph to maximize it and click on a maximized graph to return to the standard view. You can also flip one or all of the graphs between the minute and hour view by selecting one of the options from the little clock menu at the top right corner of each graph.

Overview

This section shows general statistics about this server.

Recent

This section shows statistics about actions which have occurred on this server within the last 60 seconds. The Recent Slow Pages link will show you all requests from the current request history which ran longer than the slow page threshold (defined on the Metrics Settings page).

Crash Protection (Page Aborts)

This section shows how many pages have been aborted due to each of the three types of Crash Protection. Clicking on the various Crash Protection types will show you all requests from the current request history which were aborted for that reason.

Return Code

This section lists all HTTP return codes which have been returned by this server. Each return code is also a link which will show you all requests from the current request history which have that return code.

 

NOTE: Many of the values shown on this page are counts based on all pages which have been run on this server. If you see that the number of requests which returned "200 OK" is in the thousands, the number of requests actually listed will depend upon the Request History size (which is defined in Request Settings.) It is quite possible that, if enough requests have been processed since the last "500 Internal Server Error", then clicking on that link may not show any requests at all.

Refreshing the Page

At the top of the page you will see the standard page header. At any time you can click the refresh button to update the main content. Alternatively you can select a time period from the drop-down box to update the content automatically. Selecting "None" from the drop-down box will stop the automatic refresh.
