perf daemon: Add up time for daemon/session list
Display up time for both daemon and sessions. Example: # cat ~/.perfconfig [daemon] base=/opt/perfdata [session-cycles] run = -m 10M -e cycles --overwrite --switch-output -a [session-sched] run = -m 20M -e sched:* --overwrite --switch-output -a Starting the daemon: # perf daemon start Get the details with up time: # perf daemon -v [778315:daemon] base: /opt/perfdata output: /opt/perfdata/output lock: /opt/perfdata/lock up: 15 minutes [778316:cycles] perf record -m 20M -e cycles --overwrite --switch-output -a base: /opt/perfdata/session-cycles output: /opt/perfdata/session-cycles/output control: /opt/perfdata/session-cycles/control ack: /opt/perfdata/session-cycles/ack up: 10 minutes [778317:sched] perf record -m 20M -e sched:* --overwrite --switch-output -a base: /opt/perfdata/session-sched output: /opt/perfdata/session-sched/output control: /opt/perfdata/session-sched/control ack: /opt/perfdata/session-sched/ack up: 2 minutes Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Budankov <abudankov@huawei.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: https://lore.kernel.org/r/20210208200908.1019149-18-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
