journal-upload.conf, journal-upload.conf.d — Configuration files for the journal upload service
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. Initially, the main configuration file in
/etc/systemd/ contains commented out entries showing the defaults as a guide to the
administrator. Local overrides can be created by editing this file or by creating drop-ins, as described
below. Using drop-ins for local configuration is recommended over modifications to the main configuration
In addition to the "main" configuration file, drop-in configuration snippets are read from
/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 of the files.
To disable a configuration file supplied by the vendor, the recommended way is to place a symlink
/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:
The URL to upload the journal entries to. See the description
--url= option in
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.
SSL key in PEM format.
SSL CA certificate in PEM format.
SSL CA certificate.
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(5).
