# Diagnostics
Pino provides [tracing channel](tc) events that allow insight into the
internal workings of the library. The currently supported events are:
+ `tracing:pino_asJson:start`: emitted when the final serialization process
of logs is started. The emitted event payload has the following fields:
- `instance`: the Pino instance associated with the function
- `arguments`: the arguments passed to the function
+ `tracing:pino_asJson:end`: emitted at the end of the final serialization
process. The emitted event payload has the following fields:
- `instance`: the Pino instance associated with the function
- `arguments`: the arguments passed to the function
- `result`: the finalized, newline delimited, log line as a string
