plone_log restricted Python

Trying logging from Restricted Python.

edited buildout.cfg

[instance]
event-log-level = debug

In Restricted Python I've added

request = container.REQUEST
context.plone_log(request.form.items())

it is not printing request.form.items() in plonectl/fg mode

Should i do anything else more to see it printed ?

plone_log is working fine. The edit in buildout.cfg is not required.
