Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.

Statistics range

There are two types of statistics ranges: cumulative statistics or active statistics. Cumulative statistics track statistics from transaction one in a partition. Active statistics track statistics over the recent period. For example, you can track how many transactions occurred in the latest 15 seconds.

Users can use the following command to set the statistics range for one PMI subscription.

wpfAdmin.bat|wpfadmin setStatisticsRange [cumulative|active] --id PMI_SUBSCRIPTION_ID

User can also use Java™ code, jacl script, or jython script to get the com.ibm.websphere.wpf.jmx.WPFJMX MBean instance, and change the statistics range via the MBean.

1. Execute wpfadmin setStatisticsRange active --id 1 to change the statistics range from cumulative to active.

2. Retrieve the statistics by executing "wpfadmin getTransactionCount --id 1." You will get the following output:

   PartitionName  TrnsctnCnt  TtlRspnsTm  MinTime  MaxTime StartTime   SumOfSqrs
   PK000010        0             0          260      671   1094180667170   0
   PK000009        0             0           21      242   1094180667070   0
   PK000008        0             0           99      482   1094180666990   0
   PK000007        0             0           25      200   1094180666829   0
   PK000006        0             0           75      236   1094180666759   0
   
   

   The active statistics are calculated to record the transaction statistics in the last 60 seconds. You have not generated any transactions in the last 60 seconds. Therefore, you get the transaction count and total response time 0.

3. Open a command window and run the client to generate the transactions again:

   <Install_root>\bin\launchClient 
   <Install_root>/installedApps/<CELL_NAME>/WPFSimpleSample.ear 
   -CCproviderURL=orbaloc::HOSTNAME:SERVER_RMI_PORT
   

4. Keep retrieving the statistics by executing wpfadmin getResponseTime --id 1 until you get the following output.

   PartitionName  TrnsctnCnt  TtlRspnsTm  MinTime  MaxTime  StartTime    SumOfSqrs
   PK000010            3         1695       232      827    1094180667170 1142249
   PK000009            3         2089        21      899    1094180667070 1574733
   PK000008            3         1616        99      887    1094180666990 1140270
   PK000007            3         1832        25      871    1094180666829 1228214
   PK000006            3         2210        75      895    1094180666759 1690502
   

5. Change the range from active to cumulative by executing wpfadmin setStatisticsRange cumulative --id 1

6. Optionally, if you retrieve the statistics again, we will see a different output with transaction count as 6.
