Reading z/VM monitor records
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). See z/VM: Saved Segments Planning and Administration, SC24-6322 for general information about DCSSs.
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 for z/VM.
- Access to *MONITOR records as described on
www.ibm.com/vm/pubs/ctlblk.html - Access to the kernel APPLDATA records from the Linux monitor stream.
