SM2 monitoring programs
SVC
In the case of processors with DCS in which there are several guest systems running under
VM2000, the SERVICETIME monitoring program can only be started by one of these guest
systems. Any attempts to start this function from a second guest system will be accepted
without an error message, but no DCS-specific monitored data will be returned. In general,
when using SHARED-DEVICES under VM2000, DCS-specific data will not be delivered by
any of the guest systems (see the "VM2000" manual [9]).

Note for SR2000
Information on device disconnect times cannot be supplied for devices connected to a bus.
SVC
Monitored data on SVC calls
Monitored data on SVC calls
This monitoring program records all the SVC calls in the system.
The monitored data returned will be of interest only to performance specialists, since
detailed knowledge of the internal workings of the system is required to interpret it.

SYSSTAT
Global system and category-specific monitored data
Global system and category-specific monitored data
This SM2 function provides information on important global system or category-specific
variables. The most important aspect of these variables is that they can be obtained using
event-driven methods. These monitored values make it possible to assign values which are
otherwise global by default (CPU, I/O) to individual categories, i.e. the category-related
share of the load can be determined. For precise determination of category dilation, the
SET-SYSSTAT-PARAMETER statement is required to include all devices in the monitoring
process. The queue statistics are automatically activated when the monitoring program is
started. The monitored data is written to the SM2 output file; some of the values are
displayed on screen in the CATEGORY report.
