## 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.
