SYSTEM...SERVICE(8) systemd-journal-upload.service SYSTEM...SERVICE(8)
systemd-journal-upload.service, systemd-journal-upload - Send
journal messages over the network
systemd-journal-upload.service
/usr/lib/systemd/systemd-journal-upload [OPTIONS...]
[-u/--url=URL]
[SOURCES...]
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.
-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.
On success, 0 is returned; otherwise, a non-zero failure code is
returned.
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.
