New issue 1285: Yt loglevel: Many methods, why only one working? https://bitbucket.org/yt_analysis/yt/issues/1285/yt-loglevel-many-methods-wh... scott_feister: There are several methods noted in the yt documentation that one can change the log level. The duplicated documentation is a problem for another day (that I may attempt to address, even), but not the subject of this bug report. Here is the relevant documentation: http://yt-project.org/doc/reference/configuration.html http://yt-project.org/doc/faq/index.html#how-can-i-change-yt-s-log-level And here are the methods: Method 1. From text editor: edit $HOME/.yt file to read: ``` [yt] loglevel = 50 ``` Method 2. From command line, call your script "my_script.py" that includes yt analysis: ``` $ python2.7 my_script.py --config loglevel=50 ``` Method 3. Within python: ```

...

yt.funcs.mylog.setLevel(50)

Method 4. Within python:

...

yt.config.ytcfg[“yt”, “loglevel”] = “50”

Method 5. Within python:

...

yt.config.ytcfg.set(“yt”, “loglevel”, “50”)

Method 6. Within python:

...

from yt.config import ytcfg ytcfg[ …. # (variant on methods 4 and 5)

While trying to change the log level, I learned about and tried them all, but only method 4 worked. The others leave the "[INFO]" messages on.
