Logging

The preferred way to publish logs is to use the syslog API, currently available for C in //pkg/syslog.

The library provides the ability to tag logs so that they can later be filtered upon retrieval.

In order to get logs from a device, open a shell on the device as described in this document and run: $ log_listener

To view specifics logs, add a tag specification: $ log_listener --tag foobar

See log_listener CLI for a list of available flags.

Symbolization

//tools/symbolizer should be used to symbolize stack traces. It should be pointed to the .build-id directory at the root of the SDK, where debug symbols are hosted:

symbolizer --build-id-dir .build-id
