Documentation of console API advertises admin.verbosity, but my node says it's undefined in Geth/v1.4.4-stable-8ea3c88e/linux/go1.6.2. So, how to change verbosity without restaring the node with a different --verbosity arg?

1 Answer 1


The documentation is out of date.

The verbosity option is under the debug API.

What you want is debug.verbosity(x), where x is the logging level.

If you're interested in the code, it's defined in this file.
