systemd-journal-upload

       systemd-journal-upload [OPTIONS...] [-u/--url=URL] [SOURCES...]

DESCRIPTION
       systemd-journal-upload will upload journal entries to the URL specified
       with --url. 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.

OPTIONS
       -u, --url=[https://]URL, --url=[http://]URL
           Upload to the specified address.  URL may specify either just the
           hostname or both the protocol and hostname.  https is the default.

       --system, --user
           Limit uploaded entries to entries from system services and the
           kernel, or to entries from services of current user. This has the
           same meaning as --system and --user options for journalctl(1). If
           neither is specified, all accessible entries are uploaded.

       -m, --merge
           Upload entries interleaved from all available journals, including
           other machines. This has the same meaning as --merge option for
           journalctl(1).

       -D, --directory=DIR
           Takes a directory path as argument. Upload entries from the
           specified journal directory DIR instead of the default runtime and
           system journal paths. This has the same meaning as --directory
           option for journalctl(1).

       --file=GLOB
           Takes a file glob as an argument. Upload entries from the specified
           journal files matching GLOB instead of the default runtime and
           system journal paths. May be specified multiple times, in which
           case files will be suitably interleaved. This has the same meaning
           as --file option for journalctl(1).

       --cursor=
           Upload entries from the location in the journal specified by the
           passed cursor. This has the same meaning as --cursor option for
           journalctl(1).

       --after-cursor=
           Upload entries from the location in the journal after the location
           specified by the this cursor. This has the same meaning as
           --after-cursor option for journalctl(1).

       --save-state[=PATH]
           Upload entries from the location in the journal after the location
           specified by the cursor saved in file at PATH
           (/var/lib/systemd/journal-upload/state by default). After an entry
           is successfully uploaded, update this file with the cursor of that
           entry.

       Example 1. Setting up certificates for authentication

       Certificates signed by a trusted authority are used to verify that the
       server to which messages are uploaded is legitimate, and vice versa,
       that the client is trusted.

       A suitable set of certificates can be generated with openssl:

           openssl req -newkey rsa:2048 -days 3650 -x509 -nodes \
                 -out ca.pem -keyout ca.key -subj '/CN=Certificate authority/'

           cat >ca.conf <<EOF
           [ ca ]
           default_ca = this

           [ this ]
           new_certs_dir = .
           certificate = ca.pem
           database = ./index
           private_key = ca.key
           serial = ./serial
           default_days = 3650
           default_md = default
           policy = policy_anything

           [ policy_anything ]
           countryName             = optional
           stateOrProvinceName     = optional
           localityName            = optional
           organizationName        = optional
           organizationalUnitName  = optional
           commonName              = supplied
           emailAddress            = optional
           EOF

           touch index
           echo 0001 >serial

           SERVER=server
           CLIENT=client

           openssl req -newkey rsa:1024 -nodes -out $SERVER.csr -keyout $SERVER.key -subj "/CN=$SERVER/"
           openssl ca -batch -config ca.conf -notext -in $SERVER.csr -out $SERVER.pem

           openssl req -newkey rsa:1024 -nodes -out $CLIENT.csr -keyout $CLIENT.key -subj "/CN=$CLIENT/"
           openssl ca -batch -config ca.conf -notext -in $CLIENT.csr -out $CLIENT.pem

       Generated files ca.pem, server.pem, and server.key should be installed
       on server, and ca.pem, client.pem, and client.key on the client. The
       location of those files can be specified using TrustedCertificateFile=,
       ServerCertificateFile=, ServerKeyFile=, in
       /etc/systemd/journal-remote.conf and /etc/systemd/journal-upload.conf,
       respectively. The default locations can be queried by using
       systemd-journal-remote --help and systemd-journal-upload --help.
