Response Time (millisec)
This metric measures the average time per task taken by the servlet to serve requests. By default, this metric has a warning threshold of 500 millisec and critical threshold of 1000 millisec indicating that the Forms Listener Response time is unacceptable. A critical alert is generated when the metric value reaches the critical threshold value once. It is recommended that this threshold is left at the default value
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

For this metric you can set different warning and critical threshold values for each unique combination of "Application Deployment Name" and "Server Name" objects.
If warning or critical threshold values are currently set for any unique combination of "Application Deployment Name" and "Server Name" objects, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each unique combination of "Application Deployment Name" and "Server Name" objects, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
