systemd 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.service8. See systemd.syntax7 for a general description of the syntax. 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-upload8 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. ServerKeyFile= SSL key in PEM format. ServerCertificateFile= SSL CA certificate in PEM format. TrustedCertificateFile= SSL CA certificate. 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.time7. 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. ForceCompression= Takes a boolean value, enforces using compression without content encoding negotiation. Defaults to false. systemd-journal-upload.service8 systemd1 systemd-journald.service8
