The table below shows the main monitored variables of SM2.

A table showing the links between the monitored variables and monitoring programs,
ONLINE reports, and SM2R1 report groups can be found in chapter “Variables reports” on
page 361.

Access statistics and hit rates for
DAB caches

Number of read/write accesses to DAB cache areas per second
and the percentage frequency of read/write accesses to DAB
subareas without disk access.

Access statistics for ISAM pools

Number of ISAM accesses per second to pages in the ISAM
pool and directly to disk, as well as the number of ISAM
accesses with a delay per second.
Size of the ISAM pool, reserved pages and fixed pages in PAM
pages.

Access statistics and hit rates for
hiperfiles (PFA)

Number of read/write accesses to PCA or DAB cache areas per
second, and their percentage share of the total number of read/
write accesses.
Number of failed attempts to use the cache per second.

Access statistics and hit rates for
SYMMETRIX controllers

Number of read/write accesses to SYMMETRIX controllers and
devices.
Proportion of read/write accesses handled successfully by the
cache.

Access statistics and hit rates for
controllers with cache (PCA)

Number of read/write accesses and their percentage share of
the total number of read/write accesses for PCA controllers,
cache areas, and devices.

CPU utilization

Time during which the processor is in one of the following
statuses: TU, TPR, SIH, IDLE or STOP.
In SR2000 systems, /390 time will also be output.

Number of system calls

Number of SVC calls in TU/TPR per second, and the sum of all
SVC calls per second.

Catalog access statistics

Number of read/write accesses to catalog entries/JV entries of
files per second, as well as average access times in milli-
seconds.
