This option appends current timestamp to the output file name. For example: # perf record -a --timestamp-filename ^C[ perf record: Woken up 1 times to write data ] [ perf record: Dump perf.data.2015122622265847 ] [ perf record: Captured and wrote 0.742 MB perf.data.<timestamp> (90 samples) ] # ls perf.data.201512262226584 The timestamp will be useful for identifying each perf.data after the 'perf record' support for generating multiple output files gets introduced.
