If <destination> is "gw" then the next hop gateway for the default route is used. top Run top. packet_capture [ --device <device> ] [ --frequency <frequency> ] [ --ht-location <above|below> ] [ --monitor-connection-on <monitored_device> ] Start packet capture. Start a device-based capture on <device>, or do an over-the-air capture on <frequency> with an optionally provided HT channel location. An over-the-air capture can also be initiated using the channel parameters of a currently connected <monitored_device>. Note that over-the-air captures are not available with all 802.11 devices. shell Open a command line shell. systrace [<start | stop | status>] Start/stop system tracing. Turning tracing off will generate a trace log file in the Downloads directory with all the events collected since the last time tracing was enabled. One can control the events collected by specifying categories after "start"; e.g. "start gfx" will collect only graphics-related system events. "systrace status" (or just "systrace") will display the current state of tracing, including the set of events being traced. crosh> help_advanced battery_firmware <info|check|update> info : query battery info check : checks AC Adapter is connnected or not. also checks the battery firmware is the latest or not. update : trigger battery firmware update battery_test [<test length>] Tests battery discharge rate for given number of seconds. Without an argument, defaults to 300 seconds. bt_console [<agent capability>] Enters a Bluetooth debugging console. Optional argument specifies the capability of a pairing agent the console will provide; see the Bluetooth Core specification for valid options. chaps_debug [start|stop|<log_level>] Sets the chapsd logging level.
