Queued Request Percent High rule

The WebSpeed and AppServer lists of available rules include the Queued Request Percent High. This rule highlights the percentage of client requests queued during a polling interval set for either a WebSpeed agent or AppServer server. This rule determines violations based on the number of queued requests that exceed the defined threshold setting. You can review this information to determine processing bottlenecks or tuning problems. Based on your processing needs, you can then adjust your threshold setting to help minimize the impact of these problems.

Determining the percentage of queued requests

The percentage of queued requests for either a WebSpeed agent or an AppServer server is determined by a formula that compares data from the previous poll period with data from the most current poll period; this data is always calculated on a per-poll-period basis.

This rule subtracts the number of requests queued during the current poll from the number of requests queued during the previous poll to determine the number of new queued requests for the current poll period. Also, this rule subtracts the number of requests completed during the current poll from the number of requests completed during the previous poll to determine the number of new completed requests for the current poll. Then, the number of requests queued is divided by the number of requests completed to determine the percentage of requests completed during this poll period.

Accessing the Queued Request Percent High rule page

The Queued Request Percent High rule page is accessible from the Available Rules page. On this page, you specify the threshold value, in percent form, that identifies the number of queued client requests during the polling interval that you consider acceptable. Any queued requests that cause the percentage to exceed this value will cause the alert and action criteria that you also set on this page to be triggered.
