Controlling Log Output Format
Log messages contain a number of metadata fields, in addition to the tag and priority. You can modify the output format for messages so that they display a specific metadata field. To do so, you use the -v option and specify one of the supported output formats listed below.
brief — Display priority/tag and PID of originating process (the default format).process — Display PID only.tag — Display the priority/tag only. thread — Display process:thread and priority/tag only. raw — Display the raw log message, with no other metadata fields.time — Display the date, invocation time, priority/tag, and PID of the originating process.long — Display all metadata fields and separate messages with a blank lines.
When starting logcat, you can specify the output format you want by using the -v option:
[adb] logcat [-v <format>]
Here's an example that shows how to generate messages in thread output format:
adb logcat -v thread
Note that you can only specify one output format with the -v option.
