3 Perfetto allows you to collect system-wide performance traces from Android
9 Perfetto is based on [platform services](/docs/concepts/service-model.md)
16 # Needed only on Android 9 (P) and 10 (Q) on non-Pixel phones.
21 trace with Perfetto using the `record_android_trace` script. See instructions
23 [Recording a trace through the cmdline](#recording-a-trace-through-the-cmdline)
26 ## Recording a trace
31 * Using directly the `/system/bin/perfetto` command on device [[reference](/docs/reference/perfetto…
36 * Using the on-device [System Tracing App](https://developer.android.com/topic/performance/tracing/…
38 ### Recording a trace through the Perfetto UI argument
41 **Record new trace** from the left menu.

53 Allow time for the trace to be collected (10s by default) and then you should
54 see the trace appear.

58 Your trace may look different depending on which data sources you enabled.
60 ### Recording a trace through the cmdline argument
66 downloaded from https://developer.android.com/studio/releases/platform-tools .
72 helps with getting the paths right, auto-pulling the trace once done and opening
75 `tracebox` binary to make up for the lack of tracing system services.
78 support a systrace-equivalent syntax:
83 curl -O https://raw.githubusercontent.com/google/perfetto/master/tools/record_android_trace
86 # See ./record_android_trace --help for more
87 ./record_android_trace -o trace_file.perfetto-trace -t 10s -b 32mb \
94 curl -O https://raw.githubusercontent.com/google/perfetto/master/tools/record_android_trace
95 python3 record_android_trace -o trace_file.perfetto-trace -t 10s -b 32mb \
99 **Using the on-device /system/bin/perfetto command**
101 Or, if you want to use directly the on-device binary do instead:
104 adb shell perfetto -o /data/misc/perfetto-traces/trace_file.perfetto-trace -t 20s \
110 * Ctrl+C, which normally causes a graceful termination of the trace, is not
112 interactive PTY-based session via `adb shell`.
113 * On non-rooted devices before Android 12, the config can only be passed as
114 `cat config | adb shell perfetto -c -` (-: stdin) because of over-restrictive
115 SELinux rules. Since Android 12 `/data/misc/perfetto-configs` can be used for
118 `/data/misc/perfetto-traces`. Use
119 `adb shell cat /data/misc/perfetto-traces/trace > trace` to work around.
121 `PID=$(perfetto --background)` and then `kill $PID` to stop.
123 #### Full trace config
126 control of the trace config, pass the full trace config in input.
132 If you are running on a Mac or Linux host, or are using a bash-based terminal
135 WARNING: The below command does not work on Android P because the `--txt` option
138 [_Trace configuration_ page](https://perfetto.dev/docs/concepts/config#pbtx-vs-binary-format).
183 ./record_android_trace -c config.pbtx -o trace_file.perfetto-trace
186 Or alternatively, when using directly the on-device command:
189 cat config.pbtx | adb shell perfetto -c - --txt -o /data/misc/perfetto-traces/trace.perfetto-trace
192 Alternatively, first push the trace config file and then invoke perfetto:
196 …l 'cat /data/local/tmp/config.pbtx | perfetto --txt -c - -o /data/misc/perfetto-traces/trace.perfe…
199 NOTE: because of strict SELinux rules, on non-rooted builds of Android, passing
200 directly the file path as `-c /data/local/tmp/config` will fail, hence the
201 `-c -` + stdin piping above. From Android 12 (S), `/data/misc/perfetto-configs/`
204 Pull the file using `adb pull /data/misc/perfetto-traces/trace ~/trace.perfetto-trace`
208 `/data/misc/perfetto-traces`. Use
209 `adb shell cat /data/misc/perfetto-traces/trace > trace.perfetto-trace`
