Add PEX Filter (ADDPEXFTR)

The Add Performance Explorer Filter (ADDPEXFTR) command adds a new Performance Explorer (PEX) filter to the system. Each filter is stored as a member in the QAPEXFTR file in library QUSRSYS. A Performance Explorer filter identifies the performance data that is to be collected during a Performance Explorer session, and is meant to limit the amount of data collected by specifying a compare value for specific events. If the data in the event matches the compare value, then the data will be collected. If not, the data is discarded. The filter is specified on the STRPEX (Start Performance Explorer) command.

Restrictions:

  1. This command is shipped with public *EXCLUDE authority.
  2. To use this command you must have *SERVICE special authority, or be authorized to the Service Trace function of the operating system. The Change Function Usage (CHGFCNUSG) command, with a function ID of QIBM_SERVICE_TRACE, can be used to change the list of users that are allowed to perform trace operations.
  3. You must have *EXECUTE authority to the libraries for PGMTRG, PGMFTR, OBJFTR, and *X authority to the directories for JVATRG, JVAFTR, JVACLSFTR, and PATHFTR if these parameters are specified.
  4. The following user profiles have private authorities to use the command:
    • QPGMR
    • QSRV
  5. Two threads within the same job will not be allowed to run ADDPEXFTR at the same time. The thread that issued ADDPEXFTR first will run the command to completion while the second ADDPEXFTR waits.

Filter (FTR)

Specifies the name of the Performance Explorer filter to be added. If the specified filter already exists in the QAPEXFTR file in library QUSRSYS, an error condition will occur. The user can either change the filter name or remove the existing filter using the Remove Performance Explorer Filter (RMVPEXFTR) command, and try this command again.

This is a required parameter.

name
Specify the name of the new Performance Explorer filter.

Program trigger (PGMTRG)

If a procedure entry event (*PRCENTRY) or MI entry event (*MIENTRY) occurs that matches this trigger specification, then Performance Explorer will begin collecting all events specified in the Performance Explorer definition used for the active Performance Explorer session. The events will be collected only for the thread where the trigger occurs. When the procedure exit event (*PRCEXIT) or MI exit event (*MIEXIT) occurs that matches the trigger specification, Performance Explorer will stop collecting the events specified in the Performance Explorer definition.

Note: The *MIENTRY, *MIEXIT, *PRCENTRY and *PRCEXIT events are always available in programs that have been compiled at optimization level 30 or below. For optimization level 40, these events are available only for the procedures that stack a frame on the invocation stack when called (non-leaf procedures).

The *JVAENTRY and *JVAEXIT are available in interpreted Java and Java programs running in JIT mode where the property 'os400.enbpfrcol=1' has been set. This is only for classic VM, not IBM Technology for Java.

Java trigger (JVATRG)

If a Java method entry event (*JVAENTRY) occurs that matches this trigger specification, then Performance Explorer will begin collecting all events specified in the Performance Explorer definition used for the active Performance Explorer session. The events will be collected only for the thread where the trigger occurs. When the Java method exit event (*JVAEXIT) occurs that matches the trigger specification, Performance Explorer will stop collecting the events specified in the Performance Explorer definition.

The *JVAENTRY and *JVAEXIT hooks are always enabled in interpreted Java. You can also enable these hooks when running in JIT mode by specifying the property 'os400.enbpfrcol=1'. This is only for classic VM, not IBM Technology for Java.

Examples

Example 1: Adding Disk and Memory Pool Filters 

ADDPEXFTR   FTR(FILTER1)  DSKFTR(*EQ (1 2))  MEMFTR(*EQ 3)

This command adds a new performance explorer filter named FILTER1 which will result in a member named FILTER1 being added to file QAPEXFTR in library QUSRSYS. If this filter is used when starting a performance explorer session (STRPEX command), then events will be collected if they contain disk device identifier data of '1' or '2'. In addition, the pool data for that event must contain '3'. If either the disk data or the memory pool data do not match the specified filter, then that event will not be recorded.

If an event does not contain disk device or memory pool data, then the filter does not apply to that event and those events will be collected. For example, the base event *TASKSWTIN does not contain any disk or memory pool data, so this event would still be collected.

Example 2: Adding a Disk Filter 

ADDPEXFTR   FTR(DISKFILTER)  DSKFTR(*NE (1 2))

This command adds a new performance explorer filter named DISKFILTER. If this filter is used when starting a performance explorer session (STRPEX command), then events will be collected if the event contains disk device name data that does not match '1' and does not match '2'.

If an event does not contain disk device name data, then the filter does not apply to that event and those events will be collected. For example, the base event *TASKSWTIN does not contain any disk data, so this event would still be collected.

Example 3: Adding an IP Filter 

ADDPEXFTR   FTR(IPFILTER)
            IPFTR(*EQ (*INET *STREAM '1.2.3.4'))

This command adds a new performance explorer filter named IPFILTER. If this filter is used when starting a performance explorer session (STRPEX command), then events will be collected if a communications event has an address family of *INET, the communication type is *STREAM, and the local IP address is '1.2.3.4'.

Example 3: Adding a Java Trigger 

ADDPEXFTR FTR(PERFSTRUTS) JVATRG('org/apache/struts/action'
        'ActionServlet' 'doGet' *ENTRYEXIT)

This command adds a new performance explorer filter named PERFSTRUTS. If this filter is used when starting a performance explorer session (STRPEX command), then events will start being collected when a *JVAENTRY or *JVAEXIT event occurs for the 'doGet' method in the class 'org.apache.struts.action.ActionServlet'.

Example 4: Adding a User-Defined Filter 

ADDPEXFTR   FTR(USERFILTER)
            USRDFNFTR((*EQ 1 2 20 *CHAR ('BOB' 'SAM')))

This command adds a new performance explorer filter named USERFILTER. If this filter is used when starting a performance explorer session (STRPEX command), then events will be collected if the event type is '1', the event subtype is '2' and the data at offset 20 is either 'BOB' or 'SAM'.
