How to trace multiple providers with xperf

  • 772

Xperf only lets you run one kernel session. The syntax for creating a kernel session for one provider is xperf -start MySession -on 2DA81B52-908E-7DB6-EF81-76856BB47C4F However, I cannot seem to specify multiple providers. The following does not work:

  • Multiple on switches -on A9377239-477A-DD22-6E21-75912A95FD08 -on BA798F36-2325-EC5B-ECF8-76958A2AF9B5
  • Comma separated -on A9377239-477A-DD22-6E21-75912A95FD08,BA798F36-2325-EC5B-ECF8-76958A2AF9B5
  • Space separated with or without quotes -on A9377239-477A-DD22-6E21-75912A95FD08 BA798F36-2325-EC5B-ECF8-76958A2AF9B5 or -on "A9377239-477A-DD22-6E21-75912A95FD08 BA798F36-2325-EC5B-ECF8-76958A2AF9B5"

What is the correct syntax?

    The correct syntax is using plus as a delimiter.

    xperf -start MySession -on 2DA81B52-908E-7DB6-EF81-76856BB47C4F+A9377239-477A-DD22-6E21-75912A95FD08+BA798F36-2325-EC5B-ECF8-76958A2AF9B5
