Average SNA response time measured over the last response time collection interval. Response time collection interval is specified on the AvgSampPeriod parameter of MONITORGROUP statement in the TCP/IP profile dataset The SNA response time is calculated by subtracting the Average IP Response Time from the Average Total Response Time.
The most likely causes of a high average SNA response time are an application workload spike or z/OS system resource constraints.
To further investigate system resource constraints, use the z/OS Resource Measurement Facility to evaluate workload delay metrics such as CPU and I/O for both the application and z/OS Communications Server address space to determine if possible system resource constraints exist.
This situation is triggered when the average total response time is greater than .5 seconds.
As provided, this situation is not started automatically.
