r ,1 STOP ISPOOL I i ICPTRACEI L CLOSE stops VM/370 Monitor data collection to a spool file or tape, or stops the CP internal trace If no option is
specified and theVM/370 Monitor is active, then data
collection is terminated, whether or not a spool file or tape
is in use. Internal tracing can only be stopped by specific
use of theCPTRACE option. If automatic VM/370 Monitor data
collection is active when theMONITOR STOP SPOOL command is
issued, monitoring ceases and will not start again (even if
the current time is within the bounds of theTIME operand of
theSISMON macro) unless the system abnormally terminates or
is shut down and reloaded.
TheSTOP TAPE command stops data collection by VM/370 Monitor onto tape. A zero mask is immediately stored in control
register 8, thus disablingMONITOR CALL The
last partially filled page is written out, two tape marks are
written, and the tape is rewound and unloaded. The two buffer
pages, which were obtained at the time theMONITOR START TAPE command was issued, are released.
TheSTOP CPT RACE command terminates the tracing of events
occurring on the real machine. Event recording ceases but the
pages of storage containing theCP internal trace table are
not released. Tracing can be restarted at any time by issuingMONITOR START CPTRACE. The CPTRACE and TAPE operands of the MONITOR command
have completely separate functions. Commands affecting the
status of one function have no effect on the other.

using a spool file and it is desirable to reduce the data
collected thus far. The command closes the current spool file
(thereby making it available to the reader of the recipient
virtual machine) and causes monitoring to continue
uninterrupted with a new spoolfile. AUTOdisk {ON } OFF may be used to override the specification for automatic
monitoring in theSISMON macro. Its only use is to affect the
automatic startup of monitoring. If automatic monitoring is
already active, it may only be stopped manually by aMONITOR STOP command. Note that in general, any attempts to override
the definitions of theSISMON macro with commands are
temporary. No monitor checkpointing is attempted, so that anIPL or abnormal termination causes full restoration of the
initial automatic monitoring definitions.
