Comment 3 for bug 592157

SYSLOG facility LOCAL6 is being used in HIPL. As the name suggests, it provides filtering based on facility. This lets the configuration file specify that messages from this facility will be handled differently.

The different types of messages that can be configured in the configuration file (/etc/rsyslog.d/50-default.conf) are as follows:
LOG_EMERG e.g. local6.emer
LOG_ALERT e.g local6.alert
LOG_CRIT e.g local6.crit
LOG_ERR e.g local6.err
LOG_WARNING e.g local6.warn
LOG_NOTICE e.g local6.notice
LOG_INFO e.g local6.info
LOG_DEBUG e.g local6.debug

and for all: local6.*

Other than this, program/application name based filtering is part of syslog. Output log files can be specified in configuration file (/etc/rsyslog.conf) based on application name by creating filter.
