If the code is behaving strangely, take a look in the `debug.log` file in the data directory; error and debugging messages are written there. -The `-debug=...` command-line option controls debugging; running with just `-debug` or `-debug=1` will turn -on all categories (and give you a very large `debug.log` file). +Debug logging can be enabled on startup with the `-debug` and `-loglevel` +configuration options and toggled while bitcoind is running with the `logging` +RPC. For instance, launching bitcoind with `-debug` or `-debug=1` will turn on +all log categories and `-loglevel=trace` will turn on all log severity levels. The Qt code routes `qDebug()` output to `debug.log` under category "qt": run with `-debug=qt` to see it. |
