6 years ago options for extrace:
emulator #./data/extrace
usage: ./data/extrace [options]
options include:
-a app_package enable app-level tracing for a comma
separated list of package names
-b N use a trace buffer size of N KB
-c trace into a circular buffer
-d aname,... trace the listed android categories
-e kname,... trace the listed kernel categories
-f filename use the categories written in a file as space-separated
values in a line
-p N period of memory measurement
-m N number of periods to pass
-pids N,... PIDs to take memory measurement of
-minCpu N minimal CPU usage that should trace record have to display to user
-minUss N minimal Uss that should a trace record have to be displayed to user
-n ignore signals
-s N sleep for N seconds before tracing [default 0]
-t N trace for N seconds [default 5]
-z compress the trace dump
--async_start start circular trace and return immediatly
--async_dump dump the current contents of circular trace buffer
--async_stop stop tracing and dump the current contents of circular
trace buffer
--stream stream trace to outstream as it enters the trace buffer
Note: this can take significant CPU time, and is best
used for measuring things that are not affected by
CPU performance, like pagecache usage.
--list_categories
list the available tracing categories
-o filename write the trace to the specified file instead
of outstream.
--acore add core services.
--interpret interpret dump file onlyand here is the list of supported categories for android and kernel:
