Filter output in logcat by tagname

I'm trying to filter logcat output from a real device (not an emulator) by tag name but I get all the messages which is quite a spam. I just want to read messages from browser which should be something like "browser:" or "webkit:" , but it doesn't work... Here it is what I get:

Solution 1:

use this:

adb logcat -s "TAGNAME"

Solution 2:

In case someone stumbles in on this like I did, you can filter on multiple tags by adding a comma in between, like so:

adb logcat -s "browser","webkit"

Solution 3:

Another option is setting the log levels for specific tags:

adb logcat SensorService:S PowerManagerService:S NfcService:S power:I Sensors:E

If you just want to set the log levels for some tags you can do it on a tag by tag basis.

Solution 4:

Do not depend on ADB shell, just treat it (the adb logcat) a normal linux output and then pip it:

$ adb shell logcat | grep YouTag
# just like: 
$ ps -ef | grep your_proc
