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

NAME

systemd-journal-upload.service, systemd-journal-upload - Send journal messages over the network

SYNOPSIS

systemd-journal-upload.service

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

DESCRIPTION

systemd-journal-upload will upload journal entries to the URL specified with --url=. This program reads journal entries from one or more journal files, similarly to journalctl(1). 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.

systemd-journal-upload transfers the raw content of journal file and uses HTTP as a transport protocol.

systemd-journal-upload.service is a system service that uses systemd-journal-upload to upload journal entries to a server. It uses the configuration in journal-upload.conf(5). At least the URL= option must be specified.

OPTIONS

-u, --url=[https://]URL[:PORT], --url=[http://]URL[:PORT]

Upload to the specified address. URL may specify either just the hostname or both the protocol and hostname. https is the default. The port number may be specified after a colon (":"), otherwise 19532 will be used by default.

Added in version 239.

--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.

Added in version 239.

-m, --merge

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

Added in version 239.

--namespace=NAMESPACE

Takes a journal namespace identifier string as argument. Upload entries from the specified journal namespace NAMESPACE instead of the default namespace. This has the same meaning as --namespace= option for journalctl(1).

Added in version 254.

-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).

Added in version 239.

--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).

Added in version 239.

--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).

Added in version 239.

--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).

Added in version 239.

--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.

Added in version 239.

--follow[=BOOL]

If set to yes, then systemd-journal-upload waits for input.

Added in version 239.

--key=

Takes a path to a SSL key file in PEM format, or -. If - is set, then client certificate authentication checking will be disabled. Defaults to /etc/ssl/private/journal-upload.pem.

Added in version 239.

--cert=

Takes a path to a SSL certificate file in PEM format, or -. If - is set, then client certificate authentication checking will be disabled. Defaults to /etc/ssl/certs/journal-upload.pem.

Added in version 239.

--trust=

Takes a path to a SSL CA certificate file in PEM format, or -/all. If -/all is set, then certificate checking will be disabled. Defaults to /etc/ssl/ca/trusted.pem.

Added in version 239.

-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. Note, 2048 bits of key length is minimally recommended to use for security reasons:

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:2048 -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:2048 -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=, and 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.
