When a systemd + unit's standard output/error are connected to the journal via a stream socket, the data read is split into + individual log records at newline (<literal>\n</literal>, ASCII 10) and NUL characters. If no such delimiter is + read for the specified number of bytes a hard log record boundary is artifically inserted, breaking up overly + long lines into multiple log records. Selecting overly large values increases the possible memory usage of the + Journal daemon for each stream client, as in the worst case the journal daemon needs to buffer the specified + number of bytes in memory before it can flush a new log record to disk. Also note that permitting overly large + line maximum line lengths affects compatibility with traditional log protocols as log records might not fit + anymore into a single <constant>AF_UNIX</constant> or <constant>AF_INET</constant> datagram. Takes a size in + bytes. If the value is suffixed with K, M, G or T, the specified size is parsed as Kilobytes, Megabytes, + Gigabytes, or Terabytes (with the base 1024), respectively. Defaults to 48K, which is relatively large but + still small enough so that log records likely fit into network datagrams along with extra room for + metadata. Note that values below 79 are not accepted and will be bumped to 79.</para></listitem> + </varlistentry> + </variablelist> </refsect1> |
