SYSTEMD-JOURNAL-UPLOAD(8) systemd-journal-upload 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.
