# 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
## Symbolization
`//tools/symbolize` 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:
tools/symbolize --build-id-dir .build-id
