# 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](ssh.md) 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
|
|
```
