Android has an interesting command called dumpsys to dump some system information. Even described on adb manual I think that some points should be reinforced. In order to get the complete status just run (will produce a large output):
adb shell dumpsys
Also you can apply filters to running services:
| 1 SurfaceFlinger 2 accessibility 3 account 4 activity 5 alarm 6 appwidget 7 audio 8 backup 9 battery 10 batteryinfo 11 bluetooth 12 bluetooth_a2dp 13 clipboard 14 connectivity 15 content 16 cpuinfo 17 device_policy | 18 devicestoragemonitor 19 diskstats 20 dropbox 21 entropy 22 ethernet 23 hardware 24 input_method 25 iphonesubinfo 26 isms 27 keybar 28 location 29 media.audio_flinger 30 media.audio_policy 31 media.camera 32 media.player 33 meminfo 34 mount 35 netstat | 36 network_management 37 notification 38 package 39 permission 40 phone 41 power 42 search 43 sensor 44 simphonebook 45 statusbar 46 telephony.registry 47 throttle 48 uimode 49 usagestats 50 vibrator 51 wallpaper 52 wifi 53 window |
Some examples:
adb shell dumpsys wifi
adb shell dumpsys cpuinfo
I suggest you try other items on the list above and be creative using all the power of Unix pipes. Example, to get all memory allocated by each process you can do something like:
adb shell dumpsys meminfo | grep "allocated:" | awk '{total = total + $5}END{print total}'
