Performance analysis using performance counters and trace logic

A processing system comprising:

• a first trace point configured to identify a first transaction as a transaction to be monitored;
• trace tagging logic, provided at the first trace point, configured to associate a first trace tag identifier with the first transaction;
• and
• one or more other trace points of the processing system, configured to identify the first transaction based on the first trace tag identifier.

An apparatus comprising:

• means for identifying a first transaction as a transaction to be monitored at a first means for tracing in a processing system;
• means for associating a first trace tag identifier with the first transaction, at the first means for tracing;
• and
• means for identifying the first transaction at one or more other means for tracing in the processing system, based on the first trace tag identifier.

A non-transitory computer-readable storage medium comprising code, which, when executed by a processor, causes the processor to perform operations analyzing performance of a processing system, the non-transitory computer-readable storage medium comprising:

• code for identifying a first transaction as a transaction to be monitored at a first trace point of the processing system;
• code for associating a first trace tag identifier with the first transaction, at the first trace point;
• and
• code for identifying the first transaction at one or more other trace points of the processing system based on the first trace tag identifier.
