Introduction
1.6 ON PARSING AND USING DERIVED EVENTS
For many of the sections in the chapter covering the Performance Monitoring capabilities of each box, a
set of commonly measured metrics or ‘Derived Events’ have been included. For the most part, these
derived events are simple mathematical combinations of events found within the box. (e.g. [SAMPLE])
However, there are some extensions to the notation used by the metrics.
Following is a breakdown of a Derived Event to illustrate many of the notations used. To calculate
“Average Number of Data Read Entries that Miss the LLC when the TOR is not empty”.
(TOR_OCCUPANCY.MISS_OPCODE / COUNTER0_OCCUPANCY{edge_det,thresh=0x1}))
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182.
Requires programming an extra control register (often for filtering):
• For a single field: with:Register_Name.field=value1
• For multiple fields: with:Register_Name.{field1,field2,...}={value1,value2,...}
