| # 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 | |
| ``` |
