[Users] VSDM´s logrotate makes Hosts fill up var eventually

[Sven Kieske]

Hi,

I also guess this gets so large because of the loglevels in
/etc/vdsm/logger.conf

this seems to be the default:

[logger_root]
level=DEBUG
handlers=syslog,logfile
propagate=0

[logger_vds]
level=DEBUG
handlers=syslog,logfile
qualname=vds
propagate=0

[logger_Storage]
level=DEBUG
handlers=logfile
qualname=Storage
propagate=0

[logger_metadata]
level=WARNING
handlers=metadata
qualname=irs.metadata
propagate=0

[handler_syslog]
level=WARNING
class=handlers.SysLogHandler
formatter=sysform
args=('/dev/log', handlers.SysLogHandler.LOG_USER)

[handler_logfile]
class=logging.handlers.WatchedFileHandler
args=('/var/log/vdsm/vdsm.log',)
filters=storage.misc.TracebackRepeatFilter
level=DEBUG
formatter=long

[handler_metadata]
class=logging.handlers.WatchedFileHandler
args=('/var/log/vdsm/metadata.log',)
level=WARNING
formatter=long


which is "debug" level for most loggers.

Question to the devs:

Is this really needed as a default in a production
environment?

my vdsm is a little bit older btw:

vdsm-4.12.1-4.el6.x86_64
vdsm-cli-4.12.1-4.el6.noarch
vdsm-python-4.12.1-4.el6.x86_64
vdsm-python-cpopen-4.12.1-4.el6.x86_64
vdsm-xmlrpc-4.12.1-4.el6.noarch

did this change in vdsm 4.13. ?
