DEBUG messages when log_level set to info

[knightsg]

I'm not sure if this is a bug or expected behaviour, but when log_level is set to logging.INFO, I still get debug messages in the log, like so:

July 24 22:09:39 graphios.py DEBUG graphios sleeping.
July 24 22:09:54 graphios.py DEBUG Processing spool directory /var/spool/graphios
July 24 22:09:54 graphios_backends.py DEBUG Connecting to carbon at 172.12.0.10:2004
July 24 22:09:54 graphios_backends.py DEBUG connected

July 24 22:09:54 graphios.py DEBUG deleted /var/spool/graphios/host-perfdata.1500934190
July 24 22:11:24 graphios.py INFO Processed 0 files (0 metrics) in /var/spool/graphios

Should I be seeing those debug messages?

Thanks,
Guy
