3e5f04bf64 was trying to do the right thing, but
the resulting list does not match the autogenerated order (which is the same as
the order in vtable definition). I assume the addition was done manually. Fix
the order so that dbus-docs-fresh test is not unhappy.

<title>Introduction</title>
|
|
|
|
<para><interfacename>org.freedesktop.LogControl1</interfacename> 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
|
|
<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> suite.</para>
|
|
|
|
<para>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
|
|
<filename>/org/freedesktop/LogControl1</filename>.</para>

<title>Properties</title>
|
|
|
|
<para><varname>LogLevel</varname> describes the
|
|
<citerefentry project="man-pages"><refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum></citerefentry>-style
|
|
log-level, and should be one of <literal>emerg</literal>, <literal>alert</literal>,
|
|
<literal>crit</literal>, <literal>err</literal>, <literal>warning</literal>, <literal>notice</literal>,
|
|
<literal>info</literal>, <literal>debug</literal>, in order of increasing verbosity.</para>
|
|
|
|
<para><varname>LogTarget</varname> describes the log target (mechanism). It should be one of
|
|
<literal>console</literal> (log to the console or standard output),
|
|
<literal>kmsg</literal> (log to the kernel ring buffer),
|
|
<literal>journal</literal> (log to the journal natively, see
|
|
<citerefentry><refentrytitle>systemd-journald.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>),
|
|
<literal>syslog</literal> (log using the
|
|
<citerefentry project="man-pages"><refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum></citerefentry> call).
|
|
</para>
|
|
|
|
<para>Those two properties are writable, so they may be set by sufficiently privileged users.</para>
|
|
|
|
<para><varname>SyslogIdentifier</varname> 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 <citerefentry project="man-pages"><refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum></citerefentry> call.

<title>Tools</title>
|
|
|
|
<para><command>journalctl</command> option <option>-p</option>/<option>--priority=</option> may be used
|
|
to filter log messages by log level, option <option>-t</option>/<option>--identifier=</option> may be
|
|
used to by the syslog identifier, and filters like <literal>_TRANSPORT=syslog</literal>,
|
|
<literal>_TRANSPORT=journal</literal>, and <literal>_TRANSPORT=kernel</literal> may be used to filter
|
|
messages by the mechanism through which they reached <command>systemd-journald</command>.</para>
|
|
|
|
<para><command>systemctl log-level</command> and <command>systemctl log-target</command> verbs may be
|
|
used to query and set the <varname>LogLevel</varname> and <varname>LogTarget</varname> properties of the
|
|
service manager. <command>systemctl service-log-level</command> and <command>systemctl
|
|
service-log-target</command> may similarly be used for individual services. (Services must have the
|
|
<varname>BusName=</varname> property set and must implement the interface described here. See
|
|
<citerefentry><refentrytitle>systemd.service</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for details about <varname>BusName=</varname>.)</para>
