Reading z/VM monitor records

6.10 z/VM guest

Monitoring software on Linux® can access z/VM® guest data through the z/VM *MONITOR record reader device driver.

z/VM uses the z/VM monitor system service (*MONITOR) to collect monitor records from agents on its guests. z/VM writes the records to a discontiguous saved segment (DCSS). The z/VM *MONITOR record reader device driver uses IUCV to connect to *MONITOR and accesses the DCSS as a character device.

The z/VM *MONITOR record reader device driver supports the following devices and functions:

Read access to the z/VM *MONITOR DCSS.
Reading *MONITOR records.
