Collect performance data

Usage: aperf record [OPTIONS]

Options:
  -h, --help     Print help
  -V, --version  Print version

Basic Options:
  -r, --run-name <RUN_NAME>  Name of the run
  -i, --interval <INTERVAL>  Interval (in seconds) at which performance data is to be collected [default: 1]
  -p, --period <PERIOD>      Time (in seconds) for which the performance data is to be collected [default: 10]
  -v, --verbose...           Show debug messages. Use -vv for more verbose messages
  -t, --tmp-dir <TMP_DIR>    Temporary directory for intermediate files [default: /tmp]

Data Selection:
      --dont-collect <Data Name>,<Data Name>,...
          The list of performance data to skip collection. Cannot be used with --collect_only [possible values: cpu_utilization, vmstat, disk_stats, system_info, kernel_config, interrupts, sysctl, perf_stat, processes, meminfo, netstat]
      --collect-only <Data Name>,<Data Name>,...
          The list of performance data to be collected - the others will not be collected. Cannot be used with --dont_collect [possible values: cpu_utilization, vmstat, disk_stats, system_info, kernel_config, interrupts, sysctl, perf_stat, processes, meminfo, netstat]

Perf Profiling:
      --profile                          Gather profiling data using 'perf' binary
  -F, --perf-frequency <PERF_FREQUENCY>  Frequency for perf profiling (Hz) [default: 99]

Java Profiling:
      --profile-java [<PID/Name>,<PID/Name>,...,<PID/Name>]
          Profile JVMs using async-profiler. Specify args using comma separated values. Profiles all JVMs if no args are provided

PMU Options:
      --pmu-config <PMU_CONFIG>  Custom PMU config file to use

WE RECOMMEND TO ALWAYS COLLECT AS MUCH DATA AS POSSIBLE FOR PERFORMANCE DEBUGGING, UNLESS YOU ARE SURE SOME DATA CAN BE EXCLUDED.
