MVSTHRSH

The MVS data collector monitors MVS-related resources. Exception or threshold alerts can be generated when resource usage exceeds the defined range. The MVSTHRSH parmlib member is used to define thresholds for the resources being monitored.

The alerting mechanism can cause the MVS data collector to generate alerts as follows:

• Write a message to the job log
• Write a message to the console
• Execute a predefined IMOD (REXX EXEC)
• Send an SNMP alert trap
• Send an event notification request to CA OPS/MVS
• Execute an event capture member

Following are MVS-related resources that can be monitored:

• Address spaces
• Channel, DASD, and tape devices
• UNIX System Services
• JES2
• Processors
• VTAM application availability
• Storage, paging, and swapping
