Enhancing the 'Too many events are opened.' error message with hint to use use 'ulimit -n <limit>' command. Before: $ perf record -e 'sched:*,syscalls:*' ls Error: Too many events are opened. Try again after reducing the number of events. Now: $ perf record -e 'sched:*,syscalls:*' ls Error: Too many events are opened. Probably the maximum number of open file descriptors has been reached. Hint: Try again after reducing the number of events. Hint: Try increasing the limit with 'ulimit -n <limit>' Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1432587114-14924-1-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
