  1. Install VTune which also contains emon (emon/sep driver installation is not needed): [free download](https://software.intel.com/content/www/us/en/develop/tools/vtune-profiler.html)
  2. Run emon with `--dry-run -m` options to obtain raw PMU event encodings for event of interest. For example:
  ```
  -# emon -C UNC_CHA_CLOCKTICKS,UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0,UNC_UPI_TxL_FLITS.NON_DATA --dry-run -m
  +# emon -C BR_MISP_RETIRED.ALL_BRANCHES,UNC_CHA_CLOCKTICKS,UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0,UNC_UPI_TxL_FLITS.NON_DATA --dry-run -m

  3. Run pcm-raw by specifying the obtained raw event encodings to collect into csv file. Example:
  ```
  -pcm-raw.x -csv=out.csv -e cha/config=0x0000000000400000,name=UNC_CHA_CLOCKTICKS -e qpi/config=0x0000000000409702,name=UNC_UPI_TxL_FLITS.NON_DATA -e iio/config=0x0000701000400183,name=UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0

  4. View/process the csv file using your favorite method. For example just open it in Excel.
