N3T_TN3270_Avg_IP_Resp_Time
Average IP 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 probable cause of a high average IP response time is network
congestion. Possible procedures to isolate and correct the problem
include the following:
- Determine if other TCP/IP connections from or to the same subnet
have high average IP response times. This might indicate a router
congestion problem.
- Issue a trace route command to determine the most probable routing
path.
- Determine if the routing path being used is a secondary or backup
routing path. If the primary path is not being used, identify and
fix the problem with the primary path.
- Query the routing interfaces on the routing path to determine
the number of packets dropped.
- Identify the routers along the routing path with highest numbers
of packets being dropped.
- Validate the router configuration parameters.
- Check the OSA adapter metrics to determine if adapter constraints
(such as excessive processor utilization or discards at the receive
side) exist.
This situation is triggered when the average total response time
is greater than 1.0 seconds.
Formula: Average IP Response Time > 1000
