# In this file, patterns for journalwatch are defined to blacklist all journal
# messages which are not errors.
#
# Lines starting with '#' are comments. Inline-comments are not permitted.
#
# The patterns are separated into blocks delimited by empty lines. Each block
# matches on a log entry field, and the patterns in that block then are matched
# against all messages with a matching log entry field.
#
# The syntax of a block looks like this:
#
# <field> = <value>
# <pattern>
# [<pattern>]
# [...]
#
# If <value> starts and ends with a slash, it is interpreted as a regular
# expression, if not, it's an exact match. Patterns are always regular
# expressions.
#
# Below are some useful examples. If you have a small set of users, you might
# want to adjust things like "user \w" to something like "user (root|foo|bar)".
#
# The regular expressions are extended Python regular expressions, for details
# see:
#
# https://docs.python.org/3.4/library/re.html#regular-expression-syntax
# https://docs.python.org/3.4/howto/regex.html
# http://doc.pyschools.com/html/regex.html
#
# The journal fields are explained in systemd.journal-fields(7).
