h1.m1 to h2.m21 hh.mm I I I specifies that the automatic monitoring start and stop times defined by the SYSMON macro should be temporarily overridden (until the next IPL or the next MONITOR TIME command). The FROM, ALL, and NONE options are equivalent to their
counterparts in the TIME operand of the SISMON macro (see the The FOR option
is provided specifically to simplifY data collection during
benchmarking or testing. If AUTO ON is in effect, spool
monitoring will start immediately and run for the specified
period of time. Note that if automatic monitoring is imminent
and the FOR option is specified, the period of monitoring
defined by the SISMON macro will be overridden.
r , LIMIT n ,STOP , ,SAMPLEI L specifies that the LIMIT options of the SISMON macro should be
temporarily overridden (until the next system IPL or the next MONITOR LIMIT command) • The maximum buffer count in each
spool file may be changed with the n parameter (within the 10 to 50000 range of the SISMON macro). If it is necessary to
change whether or not automatic monitoring should continue
after the limit has been reached and the spool file closed,
then the STOP, NOSTOP options may te specified. If this
should be done without changing the limit number, an asterisk
(*) may be specified for "nne When SAMPLE is specified, n defines how frequently the VM/370 Monitor is to close the monitor spool file and send it to the
virtual reader of the data reduction virtual machine. To
determine when to close the file, the VM/370 Monitor counts
the number of data samples it takes for the PERFORM, USER, and DASTAP classes. When this count equals the value of n, the VM/370 Monitor closes the file. After the file is closed,
monitoring continues using a new file.
The following example shows how the INTERVAL parameter and the
LIMIT parameter work together. If the INTERVAL parameter
specifies an interval of 30 seconds and the LIMIT parameter is
coded as LIMIT 10 SAMPLE, the VM/370 Monitor closes the spocl
file every 300 seconds (30x10). The LIMIT parameter may be specified for automatic monitoring
by using the SISMON macro instruction in module DMKSIS. Instructions for using this macro instruction are in the '18 IBM VM/370 System Programmer's Guide

real device addresses for DASD devices. The Monitor collects status information from the listed devices for the SEEKS class and writes the information to a class 7 monitor
record. Appendix C defines the format and content of the
class 7 record. The length of the list is limited only by the maximum number of device addresses that fit on one line of the
terminal at which the command is entered. Use the INclude option to create a list or to add entries to
the existing list. Use the EXclude option exclude non-2305 devices from the list. The VM/370 Monitor collects information for all
non-2305 devices not excluded. Use the DELete option to delete the entire list. Deleting the
list frees the storage the list occupied. Use the DISplay option to display the list. To reduce the
performance impact of collecting the status information, keep
the list as short as possible. CP retains the list from one
monitoring session to another. Therefore, periodically review
the list to ensure that it does not contain unnecessary
addresses.
