Wang Nan 3c1cb7e372 perf record: Split output into multiple files via '--switch-output' ... Allow 'perf record' to split its output into multiple files. For example: # ~/perf record -a --timestamp-filename --switch-output & [1] 10763 # kill -s SIGUSR2 10763 [ perf record: dump data: Woken up 1 times ] # [ perf record: Dump perf.data.2015122622314468 ] # kill -s SIGUSR2 10763 [ perf record: dump data: Woken up 1 times ] # [ perf record: Dump perf.data.2015122622314762 ] # kill -s SIGUSR2 10763 [ perf record: dump data: Woken up 1 times ] #[ perf record: Dump perf.data.2015122622315171 ] # fg perf record -a --timestamp-filename --switch-output ^C[ perf record: Woken up 1 times to write data ] [ perf record: Dump perf.data.2015122622315513 ] [ perf record: Captured and wrote 0.014 MB perf.data.<timestamp> (296 samples) ] # ls -l total 920 -rw------- 1 root root 797692 Dec 26 22:31 perf.data.2015122622314468 -rw------- 1 root root 59960 Dec 26 22:31 perf.data.2015122622314762 -rw------- 1 root root 59912 Dec 26 22:31 perf.data.2015122622315171 -rw------- 1 root root 19220 Dec 26 22:31 perf.data.2015122622315513 Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1461178794-40467-4-git-send-email-wangnan0@huawei.com Signed-off-by: He Kuang <hekuang@huawei.com> [ Added man page entry, used the re-synthesize patch in this series as a fixup ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2016-04-28 09:58:59 -03:00
