<title>Description</title>
|
|
|
|
<para><command>systemd-journal-remote</command> is a command to receive serialized journal
|
|
events and store them to journal files. Input streams are in the
|
|
<ulink url="https://www.freedesktop.org/wiki/Software/systemd/export">Journal Export Format</ulink>,
|
|
i.e. like the output from <command>journalctl --output=export</command>. For transport over the
|
|
network, this serialized stream is usually carried over an HTTPS connection.</para>
|
|
|
|
<para><filename>systemd-journal-remote.service</filename> is a system service that uses
|
|
<command>systemd-journal-remote</command> to listen for connections.
|
|
<filename>systemd-journal-remote.socket</filename> configures the network address that
|
|
<filename>systemd-journal-remote.service</filename> listens on. By default this is port 19532.
|
|
What connections are accepted and how the received data is stored can be configured through the
|
|
<citerefentry><refentrytitle>journal-remote.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
configuration file.</para>

|
<title>Sources</title>
|
|
|
|
<para>
|
|
Sources can be either "active"
|
|
(<command>systemd-journal-remote</command> requests and pulls
|
|
the data), or "passive"
|
|
(<command>systemd-journal-remote</command> waits for a
|
|
connection and then receives events pushed by the other side).
|
|
</para>
|
|
|
|
<para>
|
|
<command>systemd-journal-remote</command> can read more than one
|
|
event stream at a time. They will be interleaved in the output
|
|
file. In case of "active" connections, each "source" is one
|
|
stream, and in case of "passive" connections, each connection can
|
|
result in a separate stream. Sockets can be configured in
|
|
"accept" mode (i.e. only one connection), or "listen" mode (i.e.
|
|
multiple connections, each resulting in a stream).
|
|
</para>
|
|
|
|
<para>
|
|
When there are no more connections, and no more can be created
|
|
(there are no listening sockets), then
|
|
<command>systemd-journal-remote</command> will exit.
|
|
</para>

<listitem><para><replaceable>ADDRESS</replaceable> must be

In the first case, the server listens on port 19532 by default,

and the matching file descriptor must be inherited through

<varname>$LISTEN_FDS</varname>/<varname>$LISTEN_PID</varname>.
|

In the second case, an HTTP or HTTPS server will be spawned on
|
|
this port, respectively for <option>--listen-http=</option> and

|
<option>--listen-https=</option>. Currently, only POST requests

|
to <filename>/upload</filename> with <literal>Content-Type:
