# strip the syslog PRI part and create facility and severity fields.
# the original syslog message is saved in field %{syslog_raw_message}.
# the extracted PRI is available in the %{syslog_pri} field.

# You get %{syslog_facility_code} and %{syslog_severity_code} fields.
# You also get %{syslog_facility} and %{syslog_severity} fields if the
# use_labels option is set True (the default) on syslog_pri filter.
