systemd-journal-upload(8)

NAME

   systemd-journal-upload - Send journal messages over the network

SYNOPSIS

   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.

   -h, --help
       Print a short help text and exit.

   --version
       Print a short version string and exit.

EXIT STATUS

   On success, 0 is returned; otherwise, a non-zero failure code is
   returned.

EXAMPLES

   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.
