Web Server Response Time

This resource contains monitors specific to the response time of the current web server. The icons of the listed performance counters in the Statistic Name column will change color to reflect the listed counter's current state. Clicking any performance counter in the Statistic Name column will take you to the Performance Counter Details page for that performance counter.

If the value of a listed performance counter crosses the Warning threshold, the chart for the listed counter will display a yellow background. If the value of a listed monitor crosses the Critical threshold, the chart for the listed counter will display a red background. Hovering over any time period within the chart will display detailed information about that time period in the tooltip. Hovering over a counter will give you detailed information about that performance counter.

Counter

Expert Knowledge

HTTP Monitor

Definition:
This performance counter returns the amount of time the listed web server spends accepting incoming sessions and transmitting the requested page, in milliseconds, for the HTTP protocol.

HTTPS Monitor

Definition:
This performance counter returns the amount of time the listed web server spends accepting incoming sessions and transmitting the requested page, in milliseconds, for the HTTPS protocol.

The HTTPS monitor will not appear if the site is not configured for HTTPS. Similarly, if the Orion server is unable access an HTTP site via its configured URL, this resource will not appear because these components will automatically be disabled. You can re-enable and configure these monitors via the application editor.

Zooming

You can have the chart show a predetermined time period of data by clicking on any one of the three Zoom buttons in the head of the Zoom column. Alternatively, you can have the chart show a specific date range by dragging the mouse over an area of the chart. The time and date displayed at the top of the resource shows the amount of data currently loaded into the chart. This can be changed by clicking Edit from within the resource.

The Value from Last Poll column shows the most recent data available for the listed statistic.
