The config file appears incomplete - can you post the whole of it (if 
it's not too big)? I would have expected to see lines like

[loggers]
keys=root

[handlers]
keys=syslog

[logger_root]
level=DEBUG
qualname=(root)
handlers=syslog

[handler_syslog]
class=handlers.SysLogHandler
level=ERROR
formatter=form01
host=localhost
port=handlers.SYSLOG_UDP_PORT
facility=LOG_LOCAL0
args=(('localhost', handlers.SYSLOG_UDP_PORT), 
handlers.SysLogHandler.LOG_LOCAL0)

(the args line may wrap in this mail)

You can't encode the priority in the config file - it is automatically 
determined from the logging level (e.g. INFO -> LOG_INFO).

Note that the SysLogHandler communicates with the syslog daemon via UDP 
and there may be network problems preventing the messages getting to the 
server. If in doubt, format a UDP packet and send directly from a Python 
script (i.e. not via logging) to confirm that there is no network problem.
