Имя (Name)

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

---

Вступление (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.

Описание (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.

Инструменты (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=.)
