Performance Explorer (PEX) APIs

For information about performance explorer (PEX), see Performance explorer.

The PEX APIs are used to collect trace performance data for user-defined (application-defined) transactions and to record application-defined trace data. The user-defined transaction APIs indicate the start and end of a transaction and allow logging during a transaction.

The PEX APIs are:

• Add Trace Point (QYPEADDT, qypeAddTracePoint) records application-defined trace data.
• End Transaction (QYPEENDT, qypeEndTransaction) indicates the end of a user-defined transaction.
• Log Transaction (QYPELOGT, qypeLogTransaction) generates a transaction log record in the PEX trace data.
• Retrieve PEX Information (QYPERPEX, qypeRetrievePexInfo) returns a list of active Performance Explorer collections.
• Start Transaction (QYPESTRT, qypeStartTransaction) is called at the start of a user-defined transaction.
