Filter by priority

Filter by service


Filters the log to show entries related to the specific service. The format of the service is specific to the logging implementation. For journald these are systemd service unit names.

Filter by tag


Filters the log to show entries related to the specific syslog identifier.

Filter by message


Filters the log to show entries where the MESSAGE= field matches the specified regular expression. PERL-compatible regular expressions are used. If the pattern is all lowercase, matching is case insensitive. Otherwise, matching is case sensitive.

Filter by any field


A field is referring to the components of a structured journal entry. The match must be exact. Value can be comma separated list in which case they are automatically matched as alternatives.

Start at point

Follow the journal
