Workload Statistics attributes

This table provides hourly, daily and monthly statistics on MVS activity by workload type and service class, when the system is running in goal mode. Data is obtained from SMF type 72, subtype 3 records.

The following comprises a list of the attributes for this attribute group. The name in bold text shows how the attribute appears in the Tivoli Enterprise Portal.

Node The managed system name of the agent.

Timestamp The value is the time collected from the agent system when the data row was built and sent from the agent to the Tivoli Enterprise Monitoring Server (or stored for historical purposes). It represents the local time zone of the agent system.

Date Date when the workload activity occurred. From SMF72DAT, SMF72IST, and SMF72INT.

Time Time (rounded down to nearest hour) when the workload activity occurred. From SMF72DAT, SMF72IST, and SMF72INT.

Period Name Name of the period. This is derived using fields SMF72DAT, SMF72IST, and SMF72INT from the record as parameters in the PERIOD function.

Sysplex Name Sysplex name. This is the name of the sysplex. From SMF72XNM.

MVS System ID MVS system identification. From SMF72SID.

Workload Type MVS workload type name. From WORKLOAD_TYPE in the MVS_WORKLOAD2_TYPE lookup table.

Workload Group MVS workload group name. From R723MWNM.

Service Class Service or report class name. From R723MCNM.

Service Policy Service policy name. From R723MNSP.

Service Class Period Service or report class period number. From R723CPER.

Average Response Time Goal Average response time goal, in seconds. From R723CVAL (converted to seconds using R723CRTF) if R723CRGF is equal to X'40', otherwise set to zero.

Processor Capacity Total CPU capacity, in CPU service units. Calculated as the sum of SMF72INT*R723MCPU*1.6/R723MADJ.

Execution Velocity Goal(pct) Execution velocity goal, in percent. From R723CVAL if R723CRGF is equal to X'20', otherwise set to zero.

Goal Flag Goal flag; 0=percentile response time goal, 1= average response time goal, 2=execution velocity goal, 3= discretionary goal, 4=system specified goal. From R723CRGF.

Goal Importance Relative importance of the goal to be achieved for this service class period (1=highest - 5=lowest). Calculated as the maximum of R723CIMP.

Goal Percentile Percentile response time goal, in percent. From R723CPCT if R723CRGF is equal to X'80', otherwise set to zero.

IFA Seconds Time used for IFA processing, in seconds. Calculated as the sum of (R723IFAT*R723NFFI/256)/1000000.

IIP Seconds Time (seconds) used for IIP processing, normalised to the CP equivalent. Calculated as the sum of ((R723CSUP * R723MADJ) /(1600 * R723MCPU)) * R723NFFS / 256.

IO Count Number of I/Os calculated from the number of I/O service units. Calculated as the sum of 10000*R723CIOC/R723MIOC.

RCT Seconds Region control task time, in seconds. Calculated as the sum of R723CRCT/1000000.

Service Class Type Service class (SC) type. This can be: C for control, or R for reporting. All data in reporting SCs is also reported in a control SC, so when summaries are produced, only control SCs should be selected. From R723MSCF.

Total Processor Service Units Total CPU weighted service units. This is the sum of R723CCPU.

Total IO Service Units Total I/O service units. This is the sum of R723CIOC.

Total Main Storage Service Units Total main-storage service units. This is the sum of R723CMSO.

Total SRB Service Units Total SRB unweighted service units. Calculated as the sum of R723CSRB*10000/R723MSRB.

Total Service Units Total service units used in all transactions. This is the sum of R723CSRV.

SRB Seconds SRB CPU time calculated from the number of CPU service units, in seconds. Calculated as the sum of R723CSRB*R723MADJ/1600/R723MSRB.

Subsystem ID Name of the subsystem associated with the service class. From R723RTYP.

MVS System Name MVS system name. This is the MVS system name. From SMF72SNM.

TCB Seconds TCB CPU time calculated from the number of CPU service units, in seconds. Calculated as the sum of R723CCPU*R723MADJ/1600/R723MCPU. Note: It includes CPU time on standard CP as well as on IFA processors.

Total Delay Samples Number of delay samples. This is the sum of R723CTOT.

Active Time All Transactions Active time of all transactions, in seconds. This includes the total time that each transaction was in central storage plus any swapped-out time (long wait state time is not included). Calculated as the sum of R723CTAT*0.001024.

Elapsed Time All Transactions Elapsed time accumulated by all transactions that ended in this performance group period, in seconds. Calculated as the sum of R723CTET*0.001024.

Execution Time All Transactions Execution time accumulated by all transactions that ended in this performance group period, in seconds. Calculated as the sum of R723CXET*0.001024.

Transactions Ended Number of transactions ended. This is the sum of R723CRCP.

Transactions Ended Within Goal Number of transactions ended, within response time goal. This is the sum of R723TRDB for GOAL_PERCENTAGE less than or equal to 100.
