Specifies whether VTAM® keeps tuning statistics. See z/OS Communications Server: SNA Network Implementation Guide for further information on tuning.
The MODIFY TNSTAT and MODIFY NOTNSTAT commands allow you to activate and deactivate tuning statistics recording while VTAM is running.
- TNSTAT
- Specifies that tuning statistics should be kept or tuning statistics parameters are to be altered.
- NOTNSTAT
- Specifies that tuning statistics should not be kept.
The following operands are valid only if you code TNSTAT:
- CNSL
- Specifies that the tuning statistics records are written to the console.
- NOCNSL
- Specifies that tuning statistics records are not to be sent to the system console.
- TIME=minutes
- Specifies the number of minutes that should elapse between records. One record is written every number of minutes for each device that is keeping statistics. A record is also written when a device is deactivated or when a MODIFY TNSTAT command or MODIFY NOTNSTAT command is issued that alters tuning statistics recording for any device or if the interval is altered.
