NAME
       org.freedesktop.LogControl1 - D-Bus interface to query and set logging configuration

INTRODUCTION
       org.freedesktop.LogControl1 is a generic interface that is intended to be used by any daemon
       which allows the log level and target to be set over D-Bus. It is implemented by various
       daemons that are part of the systemd(1) suite.

       It is assumed that those settings are global for the whole program, so a fixed object path is
       used. The interface should always be available under the path /org/freedesktop/LogControl1.

DESCRIPTION
       The following interface is exposed:

           node /org/freedesktop/LogControl1 {
             interface org.freedesktop.LogControl1 {
               properties:
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("false")
                 @org.freedesktop.systemd1.Privileged("true")
                 readwrite s LogLevel = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("false")
                 @org.freedesktop.systemd1.Privileged("true")
                 readwrite s LogTarget = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("false")
                 readonly s SyslogIdentifier = '...';
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
           };






   Properties
       LogLevel describes the syslog(3)-style log-level, and should be one of "emerg", "alert",
       "crit", "err", "warning", "notice", "info", "debug", in order of increasing verbosity.

       LogTarget describes the log target (mechanism). It should be one of "console" (log to the
       console or standard output), "kmsg" (log to the kernel ring buffer), "journal" (log to the
       journal natively, see systemd-journald.service(8)), "syslog" (log using the syslog(3) call).

       Those two properties are writable, so they may be set by sufficiently privileged users.

       SyslogIdentifier is a read-only property that shows the "syslog identifier". It is a short
       string that identifies the program that is the source of log messages that is passed to the
       syslog(3) call.

TOOLS
       journalctl option -p/--priority= may be used to filter log messages by log level, option
       -t/--identifier= may be used to by the syslog identifier, and filters like
       "_TRANSPORT=syslog", "_TRANSPORT=journal", and "_TRANSPORT=kernel" may be used to filter
       messages by the mechanism through which they reached systemd-journald.

       systemctl log-level and systemctl log-target verbs may be used to query and set the LogLevel
       and LogTarget properties of the service manager.  systemctl service-log-level and systemctl
       service-log-target may similarly be used for individual services. (Services must have the
       BusName= property set and must implement the interface described here. See systemd.service(5)
       for details about BusName=.)
