JOURNAL-UPLOAD.CONF(5) journal-upload.conf JOURNAL-UPLOAD.CONF(5)
journal-upload.conf, journal-upload.conf.d - Configuration files
for the journal upload service
/etc/systemd/journal-upload.conf
/run/systemd/journal-upload.conf
/usr/lib/systemd/journal-upload.conf
/etc/systemd/journal-upload.conf.d/*.conf
/run/systemd/journal-upload.conf.d/*.conf
/usr/lib/systemd/journal-upload.conf.d/*.conf
These files configure various parameters of
systemd-journal-upload.service(8). See systemd.syntax(7) for a
general description of the syntax.
The default configuration is set during compilation, so
configuration is only needed when it is necessary to deviate from
those defaults. The main configuration file is loaded from one of
the listed directories in order of priority, only the first file
found is used: /etc/systemd/, /run/systemd/,
/usr/local/lib/systemd/ [1], /usr/lib/systemd/. The vendor version
of the file contains commented out entries showing the defaults as
a guide to the administrator. Local overrides can also be created
by creating drop-ins, as described below. The main configuration
file can also be edited for this purpose (or a copy in /etc/ if it
is shipped under /usr/), however using drop-ins for local
configuration is recommended over modifications to the main
configuration file.
In addition to the main configuration file, drop-in configuration
snippets are read from /usr/lib/systemd/*.conf.d/,
/usr/local/lib/systemd/*.conf.d/, and /etc/systemd/*.conf.d/.
Those drop-ins have higher precedence and override the main
configuration file. Files in the *.conf.d/ configuration
subdirectories are sorted by their filename in lexicographic
order, regardless of in which of the subdirectories they reside.
When multiple files specify the same option, for options which
accept just a single value, the entry in the file sorted last
takes precedence, and for options which accept a list of values,
entries are collected as they occur in the sorted files.
When packages need to customize the configuration, they can
install drop-ins under /usr/. Files in /etc/ are reserved for the
local administrator, who may use this logic to override the
configuration files installed by vendor packages. Drop-ins have to
be used to override package drop-ins, since the main configuration
file has lower precedence. It is recommended to prefix all
filenames in those subdirectories with a two-digit number and a
dash, to simplify the ordering. This also defines a concept of
drop-in priorities to allow OS vendors to ship drop-ins within a
specific range lower than the range used by users. This should
lower the risk of package drop-ins overriding accidentally
drop-ins defined by users. It is recommended to use the range
10-40 for drop-ins in /usr/ and the range 60-90 for drop-ins in
/etc/ and /run/, to make sure that local and transient drop-ins
take priority over drop-ins shipped by the OS vendor.
To disable a configuration file supplied by the vendor, the
recommended way is to place a symlink to /dev/null in the
configuration directory in /etc/, with the same filename as the
vendor configuration file.
All options are configured in the [Upload] section:
URL=
The URL to upload the journal entries to. See the description
of --url= option in systemd-journal-upload(8) for the
description of possible values. There is no default value, so
either this option or the command-line option must be always
present to make an upload.
Added in version 232.
ServerKeyFile=
SSL key in PEM format.
Added in version 232.
ServerCertificateFile=
SSL CA certificate in PEM format.
Added in version 232.
TrustedCertificateFile=
SSL CA certificate.
Added in version 232.
NetworkTimeoutSec=
When network connectivity to the server is lost, this option
configures the time to wait for the connectivity to get
restored. If the server is not reachable over the network for
the configured time, systemd-journal-upload exits. Takes a
value in seconds (or in other time units if suffixed with
"ms", "min", "h", etc). For details, see systemd.time(7).
Added in version 249.
Compression=
Configures compression algorithm to be applied to logs data
before sending. Takes a space separated list of compression
algorithms, or "no". Supported algorithms are "zstd", "xz", or
"lz4". Optionally, each algorithm followed by a colon (":")
and its compression level, for example "zstd:4". The
compression level is expected to be a positive integer. When
"no" is specified, no compression algorithm will be applied to
data to be sent. This option can be specified multiple times.
If an empty string is assigned, then all previous assignments
are cleared. Defaults to unset, and all supported compression
algorithms with their default compression levels are listed.
Example:
Compression=zstd:4 lz4:2
Even when compression is enabled, the initial requests are
sent without compression. It becomes effective either if
"ForceCompression=" is enabled, or the server response
contains "Accept-Encoding" headers with a list of compression
algorithms that contains one of the algorithms specified in
this option.
Added in version 258.
ForceCompression=
Takes a boolean value, enforces using compression without
content encoding negotiation. Defaults to "false".
Added in version 258.
Header=
Specifies an additional HTTP header to be added to each
request to a URL. Takes a pair of header name and value
separated with a colon(":"), e.g. "Name:Value". Header name
can contain alphanumeric values, "_" and "-" symbols
additionally. This option may be specified more than once, in
which case all listed headers will be set. If the same header
name is listed more than once, all its unique values will be
concatenated with comma. Setting Header= to empty string
clears all previous assignments.
Example:
Header=HeaderName: HeaderValue
Header=HeaderName: NewValue
Header=HeaderName: HeaderValue
adds "HeaderName" header with "HeaderValue, NewValue" to each
HTTP request.
Added in version 258.
systemd-journal-upload.service(8), systemd(1),
systemd-journald.service(8)

be available at all times. If /usr/local/ is a separate
partition, it may not be available during early boot, and must
not be used for configuration.
