IPython controllers and engines (and your own processes) can broadcast log messages
|
|
|
by registering a `zmq.log.handlers.PUBHandler` with the `logging` module. The
|
|
|
logger can be configured using command line options or using a cluster
|
|
|
directory. Cluster directories contain config, log and security files and are
|
|
|
usually located in your ipython directory and named as "profile_name".
|
|
|
See the `profile` and `profile-dir` options for details.
