The WLM Service Delivered Summary report tracks information
concerning CEC (Central Electronic Complex) and LP (Logical
Partition) configuration and LP processor resource usage, as
well as providing an overview of each workload's CP (Central
Processor) and special purpose processor resource
utilization. The report can be presented at a monthly,
weekly, daily, or hourly level, and can be summarized either
by WLM Importance, WLM Workload, WLM Service Class or WLM
Report Class. 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 either SVC (Service)
Class or RPT (Report) Class. These options are discussed in
Section 2.2.7.
DATA ELEMENTS
The elements reported are grouped into the following
sections:
o CEC Configuration Summary
o LP Configuration Summary
o LP Processor Usage Summary
o Workload Usage Summary
CEC CONFIGURATION SUMMARY
This section presents basic information concerning the CEC
(Central Electronic Complex) where the LPAR being measured
resides.
CEC Model The model of the CEC under study, a
Definition: concatenation of the CA MICS data elements
CPUMOD (Processor Model Family) and
CPCMODID (CPC Model Identifier).
CEC Serial The serial number of the CEC, taken from
Number: CA MICS data element PRSMCEC (PR/SM LPAR
Central Complex).
Percent CEC The total busy of all shared LPs in the CEC,
Busy: expressed as a percentage and derived from the
CA MICS data elements PRSMTTDT (Total Dispatch
Time) and DURATION.
Shared CPs The number of shared CPs defined within the CEC
Defined in available for use in LPs, derived from CA MICS
CEC: data elements PRSMACP (Avg CP Processors in
Complex) and PRSMADP (Avg Dedicated
Processors).
Avg zAAP The average number of System z9 Application
Processors Assist Processors (zAAPs) assigned for use by
in CEC: the PR/SM LPAR feature, derived from CA MICS
data element PRSMAZP (Avg zAAP Processors in
Complex) and DURATION. This data element is
valid only for System z9 and later servers.
Avg zIIP The average number of System z9 Integrated
Processors Information Processors (zIIPs) assigned for use
in CEC: by the PR/SM LPAR feature, derived from CA MICS
data element PRSMASP (Avg zIIP Processors in
Complex) and DURATION. This data element is
valid only for System z9 and later servers.
LP CONFIGURATION SUMMARY
This section presents measurement data about capacity sizing
and processor resource usage within the LP being reported on.
Phys. CPU The number of CPU service units that can be
Adjust. expended in one clock second by CPs in this LP,
Factor: from CA MICS data element CPUSUSEC (Physical
CPU Adjustment Factor). This value is used to
calculate the processor usage in MSUs, millions
of service units per hour.
MSUs Avail. The theoretical maximum capacity of the LP
to Image: under study in MSUs per hour, from CA MICS data
element CPUSUAVL and based on the CEC model and
the number of CPs defined to the LP under
measurement.
Weighted LP The actual capacity of the LP under study in
Cap. (MSUs): MSUs. This value is computed as a function of
the CA MICS data elements CPUBPS (Partition
Processor Weight) and PRSMTWGT (Sum of All
Partitions Weights), and the MSUs Available to
image value above. This is the amount of
processor resources available for all CPs
active within the LP when LP weighting is in
effect.
Weighted LP The share of processor resources available for
Share Pct.: all active CPs in the LP under measurement,
expressed as a percentage. This is the named
result of the initial calculation of Weighted
LP Cap. (MSUs) above and is effective once LP
weight management is active.
No. of The maximum number of CPs and special purpose
Available processors present in the configuration, from
Procs.: CA MICS data element CPUNOCPU (Max Number of
Configured Processors).
Avg. CPs The average number of CPs in use by the LP
in Use: under study, from CA MICS data element CPUAVCPU
(Avg Number of Assigned CP Processors).
Avg. zAAPs The average number of zAAPs in use by the LP
in Use: under study, from CA MICS data element CPUAVOZP
(Avg Number of Online zAAP Processors).
Avg. zIIPs The average number of zIIPs in use by the LP
in Use: under study, from CA MICS data element CPUAVOSU
(Avg Number of Online zIIP Processors).
CPs Required The minimum number of CPs required to sustain
for LP Wgt.: the weighted LP capacity. This value is
computed as a function of the Weighted LP Share
Percentage and the number of shared CPs defined
in the CEC discussed previously. It is
displayed as a decimal value. Round it upwards
to the next integer and then compare the result
against the Avg. CPs in Use value. If fewer
CPs are in actual use, then potentially there
will not be sufficient processor resources
available to address the workload requirements.
LP Shr. Proc. The ratio of LP processor usage as a function
Use Ratio: of z/OS busy time. This value is sometimes
called "Short CPs" and is an indicator of work
versus resources. Generally, a value greater
than 1.25 is cause for concern and would
indicate a potential performance impact.
Weighted CP The effective speed of a single CP within the
Speed (MSUs): LP configuration. This is a function of the CPs
Required for LP Wgt. calculation above and the
Avg. CPs in Use value. This value becomes
important when large processor tasks, such as
CICS regions, are executing within the LP
because the task execution can be frequently
interrupted, causing poor or erratic response
times within such regions.
LP PROCESSOR USAGE SUMMARY
This section contains measurement data concerning how
processor resources are consumed within the LP. Information
is included to help with planning for subcapacity license
charging. Processor delays are presented.
Reporting The timespan, in seconds, covered by the
Interval: report, from CA MICS common data element
DURATION.
LP CP Busy The total processor busy time consumed by CPs
Time (sec): assigned to this LP for the reporting interval,
expressed in seconds. This value is from
CA MICS data element CPUTOBTM (Total Time CP
Processors Busy)
zAAP The amount of TCB CPU time consumed within this
Eligible service/report class period while executing
Time (sec): zAAP eligible work on standard CP processors.
This value is from CA MICS data element
SECZAPCT (zAAP Eligible CPU Time on CP).
zIIP The amount of TCB CPU time consumed within this
Eligible service/report class period while executing
Time (sec): zIIP eligible work on standard CP processors.
This value is from CA MICS data element
SECSUPCT (zIIP Eligible CPU Time on CP).
Percent The total processor busy time consumed by CPs
LP CP Busy: assigned to this LP for the reporting interval,
expressed as a percentage. This value is from
CA MICS data element CPUPCBSY (Pct CP
Processors Busy).
LP zAAP Busy The total processor busy time consumed by zAAPs
Time (sec): assigned to this LP for the reporting interval,
expressed in seconds. This value is from
CA MICS data element CPUZPBTM (Total Time zAAP
Processors Busy)
Percent The total processor busy time consumed by zAAPs
LP zAAP Busy: assigned to this LP for the reporting interval,
expressed as a percentage. This value is from
CA MICS data element CPUPCBZP (Pct zAAP
Processors Busy).
LP zIIP Busy The total processor busy time consumed by zIIPs
Time (sec): assigned to this LP for the reporting interval,
expressed in seconds. This value is from
CA MICS data element CPUSUBTM (Total Time zIIP
Processors Busy)
Percent The total processor busy time consumed by zIIPs
LP zIIP Busy: assigned to this LP for the reporting interval,
expressed as a percentage. This value is from
CA MICS data element CPUPCBSU (Pct zIIP
Processors Busy).
Avg. MSUs The mean CP resources consumed, expressed in
Consumed: MSUs per hour. This value is derived using the
LP CP Busy Time value described above and the
Phys. CPU Adjust. Factor previously described.
This value can be used in conjunction with the
workload consumption values in the next section
as a starting point for capacity planning. You
can also use it to begin the subcapacity
license charging process.
Uncaptured The CP resources that cannot be allocated to a
CP MSUs: given WLM defined workload and remain an
overhead to the LP capacity.
Defined The limit of LP capacity specified by the user
Capacity in MSUs, from CA MICS data element CPUDEFLM. If
Limit: this value is specified, then LP capacity will
be governed by use of the "four hour rolling
average" of actual CP consumption; when the CP
consumption exceeds this limit, then the LP is
"soft capped."
Avg. 4 Hour The rolling average of LP consumption, in MSUs
Rolling MSUs: mentioned above and from CA MICS data element
CPUAVLAC. This value can be tracked over time
to help determine what an appropriate value for
the Defined Capacity Limit should be if the
user wants to implement subcapacity licensing
charges.
Percent Ready The time on average that tasks ready for
Tasks Wait: dispatch must wait for an available CP,
expressed as a percentage. This value is
computed by first summing the appropriate
CPURxx values and then dividing this sum by the
SAMPLES value. Use this measure in conjunction
with the LP Shr. Proc. Use Ratio to help
identify intervals where a shortage of
processor resources is affecting throughput.
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 understand 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.
