Rejected Request Percent High rule

The WebSpeed and AppServer lists of available rules include the Rejected Request Percent High rule. This rule highlights the percentage of client requests rejected during a polling interval set for either a WebSpeed agent or AppServer Server. It determines violations based on the number of initiated 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 from preventing client requests from being serviced.

Determining the percentage of rejected requests

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

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

Accessing the Rejected Request Percent High rule page

The Rejected 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 rejected client requests during the polling interval that you consider acceptable. Any rejected requests that exceed this value will cause the alert and action criteria that you also set on this page to be triggered.
