This WLM Service Delivered report tracks information
concerning transaction service delivered, resources consumed,
and workload throughput and delays, at a monthly, weekly,
daily, or hourly level.
Each logical page of the report presents the information for
one service class and one service class period within one
importance level for each single LPAR. This is also the
order of the pages.
The report can also be summarized so that each page presents
the information for one service class and one service class
period within one importance level summarized for all LPARs
in a sysplex.
When the zone option is specified for the inquiry, each page
is expanded into a page for each zone in the incoming data
that may have been filtered by data selection parameters.
When the hour option is specified for the inquiry, each page
may be expanded into two or three pages to contain a column
for each hour found in the incoming data that may have been
filtered by data selection parameters.
Additionally, a CSV file can be optionally created for later
use by Q&R to generate charts and graphs.
REPORT OPTIONS
Standard data selection options are supported as well as
SYSID selection and external data selection. Additionally,
input data may be further filtered by Sysplex or SVC
(Service) Class. These options are discussed in Section
2.2.7.
DATA ELEMENTS
The elements reported are divided into the following
categories:
o Service Delivered
o Resources Consumed
o Throughput and Delays
SERVICE DELIVERED
This section presents measurement data about SRM transaction
volume and service received for transactions executing within
the WLM Service Class Period being reported on.
Reporting The timespan, in seconds, covered by the
Interval: report, from CA MICS common data element
DURATION.
Total The total number of SRM transactions that ended
Transactions: in the reporting interval, from CA MICS data
element SECTORCP.
Transactions The rate of SRM transaction execution (ended
per Second: transactions), per second, from CA MICS data
element SECPSRCP.
Total SRM Svc The total number of service units expended
Units (k): during the reporting interval, expressed in
thousands. This value is derived from CA MICS
data element SECTOSRV, divided by 1,000.
SRM Svc Units The rate of service units expended per second,
per Second: expressed in thousands. This value is derived
from CA MICS data element SECPSSRV divided by
1,000.
Avg. Tx Queue The mean time transactions spent waiting for
Time (secs): execution, expressed in seconds and from CA
MICS data element SECAVQUE.
Avg. Tx Exec The mean time transactions spent in execution,
Times (secs): expressed in seconds and from CA MICS data
element SECAVXET.
RESOURCES CONSUMED
This section presents measurement data about processor,
paging, and I/O resources used by transactions executing
within the WLM Service Class Period being reported on.
Total CP Time The total time transactions executed on CPs
(secs): (central processors), expressed in seconds and
from CA MICS data element SECCPUTM.
zAAP on CP The total time the zAAP eligible Java work
Time (secs): spent executing on CPs (central processors),
expressed in seconds and from CA MICS data
element SECZAPCT.
Total zAAP The total time transactions executed on zAAPs
Time (secs): (z/OS application assist processors), expressed
in seconds and from CA MICS data element
SECZAPTM.
zIIP on CP The total amount of TCB CPU time consumed
Time (secs): within this service class period while
executing zIIP eligible work on standard CP
processors, from CA MICS data element SECSUPCT.
Total zIIP The total amount of normalized TCB CPU time
Time (secs): executed on zIIP processors, expressed in
seconds and from CA MICS data element SECSUPTM.
Total DASD The total number of non-paging I/O operations
I/O Count: (SSCHs) done to DASD devices, expressed in
thousands and from CA MICS data element
SECDCNT.
$SCOL
DASD I/Os The number of non-paging I/O operations (SSCHs)
per Second: performed per second. This value is computed by
dividing the Total DASD I/O Count defined above
by the CA MICS data element DURATION.
DASD I/Os per The number of non-paging I/O operations (SSCHs)
CPU Second: performed per CPU (TCB) second. This value is
computed by dividing the Total DASD I/O Count
defined above by the CA MICS data element
SECCPUTM. This is a relative measure of
workload I/O intensity and can be used to
compare workloads within or across WLM service
classes.
Avg. Page Ins The number of pages moved into central storage
per Second: per second, from CA MICS data element SECPSPIN.
THROUGHPUT AND DELAYS
This section contains measurement data that tells how well
transactions actually perform, including summary information
about where processing delays occur. This provides the
ability to do first-level problem analysis when service
objectives are not being met.
Average MPL: The mean number of tasks active and executing
within the WLM Service Class Period for the
reporting interval, from CA MICS data element
SECAVMPL.
Execution The relative measure of how fast transactions
Velocity: are executing with the WLM Service Class
Period, expressed as a percentage and from
CA MICS data element SECEXVEL. Higher values
indicate that transactions have experienced few
delays; lower values indicate more delays. A
zero value indicates that no processor
resources were consumed during the reporting
interval.
Performance A measure of how well transactions are
Index: performing with respect to their WLM-defined
goals, from CA MICS data element SECPINDX. A
value of 1 indicates that transactions are
meeting their respective goals exactly. Values
above 1 indicate that goals are being missed.
Values below 1 indicate that goals are being
exceeded.
CP Usage The ratio of CPU Delay Samples to the sum of
Delay Ratio: CPU Using and CPU Delay Samples. This is
essentially the inverse of the CPU portion of
the Execution Velocity calculation, and can be
used to see when processor delays are
occurring. Use this value in conjunction with
the Execution Velocity and Performance Index to
determine if service objectives are not being
met and if processor delay is responsible.
zAAP Usage The ratio of zAAP Delay Samples to the sum of
Delay Ratio: zAAP Using and zAAP Delay Samples. This value
can be used to see when zAAP delays are
occurring. Use this value in conjunction with
the Execution Velocity and Performance Index to
determine if service objectives are not being
met and if zAAP processor delay is responsible.
zIIP Usage The ratio of zIIP Delay Samples to the sum of
Delay Ratio: zIIP Using and zIIP Delay Samples. This value
can be used to see when zIIP delays are
occurring. Use this value in conjunction with
the Execution Velocity and Performance Index to
determine if service objectives are not being
met and if zIIP processor delay is responsible.
Pct Processor The sum of the following CA MICS data elements:
Delays: SEDPCDCP (Pct Wait - CPU on CP)
SEDPCZPD (Pct Wait - CPU on zAAP)
SEDPCSUD (Pct Wait - CPU on zIIP)
This value represents the amount of processor
delay as a function of all sampled delays.
Pct I/O The sum of the following CA MICS data elements:
Related SEDPCDSD (Pct Wait - DASD I/O Delay) ,
Delays: SEDPCDHS
(Pct Wait - Std Hiperspc Pg-In from Aux)
SEDPCDES
(Pct Wait - ESO Hiperspc Pg-In from Aux)
SEDPCDVI (Pct Wait - VIO Page-In from Aux)
This value represents the amount of I/O delays
as a function of all sampled delays.
Pct Storage The sum of the following CA MICS data elements:
Delays: SEDPCDMP (Pct Wait - MPL Delay)
SEDPCDSI (Pct Wait - Swap-In)
SEDPCDPC (Pct Wait - CSA Page-In from Aux)
SEDPCDPP (Pct Wait - Pvt Page-In from Aux)
SEDPCDXM
(Pct Wait - Cross Mem Page-In from Aux)
This value represents the amount of storage
delays as a function of all sampled delays.
Pct Misc. The sum of the following CA MICS data elements:
Delays: SEDPCCOD (Pct Wait - Resource Contention)
SEDPCCRD (Pct Wait - Crypto Processors)
SEDPCFQD (Pct Wait - Feature Queue)
This value represents the amount of other
delays as a function of all sampled delays.
