seveniruby:systrace seveniruby$ python2 systrace.py --help
Usage: systrace.py [options] [category1 [category2 ...]]

Example: systrace.py -b 32768 -t 15 gfx input view sched freq

Options:
  -h, --help            show this help message and exit
  -o FILE               write trace output to FILE
  -j, --json            write a JSON file
  --link-assets         (deprecated)
  --asset-dir=ASSET_DIR
                        (deprecated)
  -e DEVICE_SERIAL_NUMBER, --serial=DEVICE_SERIAL_NUMBER
                        adb device serial number
  --target=TARGET       choose tracing target (android or linux)
  --timeout=TIMEOUT     timeout for start and stop tracing (seconds)
  --collection-timeout=COLLECTION_TIMEOUT
                        timeout for data collection (seconds)
  -t N, --time=N        trace for N seconds
  -b N, --buf-size=N    use a trace buffer size  of N KB
  -l, --list-categories
                        list the available categories and exit

  Atrace options:
    --atrace-categories=ATRACE_CATEGORIES
                        Select atrace categories with a comma-delimited list,
                        e.g. --atrace-categories=cat1,cat2,cat3
    -k KFUNCS, --ktrace=KFUNCS
                        specify a comma-separated list of kernel functions to
                        trace
    --no-compress       Tell the device not to send the trace data in
                        compressed form.
    -a APP_NAME, --app=APP_NAME
                        enable application-level tracing for comma-separated
                        list of app cmdlines
    --from-file=FROM_FILE
                        read the trace from a file (compressed) rather than
                        running a live trace

  Atrace process dump options:
    --process-dump      Capture periodic per-process memory dumps.
    --process-dump-interval=PROCESS_DUMP_INTERVAL_MS
                        Interval between memory dumps in milliseconds.
    --process-dump-full=PROCESS_DUMP_FULL_CONFIG
                        Capture full memory dumps for some processes. Value:
                        all, apps or comma-separated process names.
    --process-dump-mmaps
                        Capture VM regions and memory-mapped files. It
                        increases dump size dramatically, hence only has
                        effect if --process-dump-full is a whitelist.

  Ftrace options:
    --ftrace-categories=FTRACE_CATEGORIES
                        Select ftrace categories with a comma-delimited list,
                        e.g. --ftrace-categories=cat1,cat2,cat3

  WALT trace options:
    --walt              Use the WALT tracing agent. WALT is a device for
                        measuring latency of physical sensors on phones and
                        computers. See https://github.com/google/walt

使用systrace获得某个app的最长卡顿帧的截图

11111111 占楼

继续占个楼,等作业

占位占位,1234

等待后续写作业用

先占楼 :stuck_out_tongue:

systrace 只能使用真机吗?模拟器是不是不可以?

我公司app有非常多的红色,但是没感觉卡顿,还是不太明白如何分析?
