Queued Request Percent High rule

The WebSpeed and AppServer lists of available rules include Queued Request Percent High. This rule highlights the percentage of client requests queued during a polling interval set for either a WebSpeed agent or an 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. You can 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. The rule then determines the number of new queued requests for the current poll period. This rule also 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. The number of requests queued is then 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

Accessible from the Available Rules page is the Queued Request Percent High rule page. On this page, you specify the threshold value as a percentage. The value 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 set on this page to be triggered.
