| <title>Description</title> |
| |
| <para><command>systemd-journal-upload</command> will upload journal entries to the URL specified |
| with <option>--url=</option>. This program reads journal entries from one or more journal files, |
| similarly to |
| <citerefentry><refentrytitle>journalctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>. |
| Unless limited by one of the options specified below, all journal entries accessible to the user |
| the program is running as will be uploaded, and then the program will wait and send new entries |
| as they become available.</para> |
| |
| <para><filename>systemd-journal-upload.service</filename> is a system service that uses |
| <command>systemd-journal-upload</command> to upload journal entries to a server. It uses the |
| configuration in |
| <citerefentry><refentrytitle>journal-upload.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>. |
| At least the <varname>URL=</varname> option must be specified.</para> |
