| # 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 |
| ``` |
| |
| See [log_listener CLI] for a list of available flags. |
| |
| ## 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 |
| ``` |
