These attributes represent the Workload Manager (WLM) service class information for the selected service class period over the recent historical period. There is one row of data per an RMF Monitor III reporting interval or group of RMF Monitor III intervals.
Actual Velocity/Percentile (RMF metric) Service Class Period Actual Velocity (If SUMEVG returned). If Goal Type is Velocity this is the velocity percentile value achieved. Otherwise this column is blank.
Average Execution Time (RMF metric) Service Class Period Average Execution Time. For CICS transactions, this includes execution time in AOR and following regions.
For IMS transactions, this includes execution time within the MPR.
For Batch, TSO, and so on, this is the average time that transactions spent in execution.
In the Average Response Time columns, zeros will show up for server service classes in most cases, because theirtransactions are address spaces, and response times are available only for ended transactions. So there are only numbers, when one of the address spaces in that service class ends, or is RESET via operator command.
Average Response Time (RMF metric) Service Class Period Actual Response Time in milliseconds to 1 decimal place (tenths of milliseconds).
The time a job was delayed due to TYPRUN=HOLD or TYPRUN=JCLHOLD is NOT included in any of the transaction times.
In all other cases, this is the average time that transactions spent waiting on a JES or APPC queue. Also note that queue time may not always be meaningful, depending on how the customer schedules work. For example, if a customer submits jobs in hold status and leaves them until they are ready to be run, all of the held time counts as queued time. That time may or may not represent a delay to the job.
In the Average Response Time columns, zeros will show up for server service classes in most cases, because theirtransactions are address spaces, and response times are available only for ended transactions. So there are only numbers, when one of the address spaces in that service class ends, or is RESET via operator command.
Duration (RMF metric) Service Class Period Goal Duration. Service class period duration in unweighted CPU service units (that means, not multiplied with the service coefficients) per second.
A duration is required in all but the last service class period. For single periods or for the last period of multiple periods this value is always zero.
Goal Importance (RMF metric) Service Class Period Importance.
Goal Percentile (RMF metric) Service Class Period Percentile Goal If Goal Type is Percentile Response Time this is the percent of transactions that should meet the Response Goal value desired. Otherwise this column is zero.
Goal Type (RMF metric) Service Class Period Goal Type. The type of goal for the service class period. Valid values:
Goal Value (RMF metric) Service Class Period Response Time Goal. If Goal Type is either Average Response Time or Percentile Response Time this is the response time value desired. Otherwise this column is blank.
Managed System The name of the managed system from which this data is collected. The name has the format <plexname>:<smfid>:MVSSYS, where <plexname> is the Sysplex this LPAR resides in and <smfid> is the unique identifier for the system.
Perf Index = Goal % / Actual %
For
velocity goal the Actual % is:Actual(%)= (# Using Samples / (# Using Samples + # Delay Samples)) * 100
Using
Samples is the number of samples categorized as using CPU or active
in I/O. All other sample categories like waiting for CPU or waiting
for I/O are considered Delay Samples.Perf Index = Actual (sec) / Goal (sec)
For
average response time goal the Actual (sec) value is the average response
time over all transactions in the sampling period. Bucket | Percentage of Goal | Example for 2 second goal |
---|---|---|
1 | <50% | <1.0 |
2 | 60% | >1.0 to 1.2 sec |
3 | 70% | >1.2 to 1.4 sec |
4 | 80% | >1.4 to 1.6 sec |
5 | 90% | >1.6 to 1.8 sec |
6 | 100% | >1.8 to 2.0 sec |
7 | 110% | >2.0 to 2.2 sec |
8 | 120% | >2.2 to 2.4 sec |
9 | 130% | >2.4 to 2.6 sec |
10 | 140% | >2.6 to 2.8 sec |
11 | 150% | >2.8 to 3.0 sec |
12 | 200% | >3.0 to 4.0 sec |
13 | 400% | >4.0 to 8.0 sec |
14 | >400% | >8.0 sec |
Recording End Time Time at the end of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.
Recording Start Time Time at the start of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.
Recording Read Time The time interval required to read the interval data in the current row. The valid format is yy/mm/dd hh:mm:ss.
Resource Group Name (RMF metric) The resource group name associated with this service class. You can assign only one resource group per service class in a service policy. You can override the resource group assigned to a service class in each service policy.
RMF Status Status indications for availability of RMF and lock data.
Sample Period Sample period in seconds.
Service Class The service class name. Valid value is a string, with a maximum of eight characters. This field displays unavailable if the system is in compatibility mode. If a job changes its service class during the report interval, RMF displays eight asterisks (********) instead of the service class name. If the service class is not available, RMF displays eight dashes (--------).
Service Class Description (RMF metric) An area of 32 characters describing the service class. The descriptive text is available to performance monitors for reporting.
Service Class SUs/Second (RMF metric) Transactions per second that ended during the interval.
Transaction Rate (RMF metric) The transactions per second that ended during the current interval.
Workload Name The name of the workload that contains the service class. Valid value is a simple text string of from 1 through 8 characters; for example, BATAVGWTIMECH.
