As proposed in #8857, this adds a Logger subclass that writes structured log messages via journald's native protocol by calling sd_journal_sendv. The feature therefore depends on the systemd library. sd_journal_sendv is available since the early days (systemd v38), so a version check is probably superflous. We add the following fields to each record: - MESSAGE: The log message - PRIORITY (aka severity): Numeric severity as in RFC5424 section 6.2.1 - SYSLOG_FACILITY: Numeric facility as in RFC5424 section 6.2.1 - SYSLOG_IDENTIFIER: If provided, use value from configuration. Else use systemd's default behaior, which is to determine the field by using libc's program_invocation_short_name, resulting in "icinga2". - ICINGA2_FACILITY: Facility as in Log::Log(..., String facility, ...), e.g. "ApiListener" - some more fields are added automatically by systemd Fields are stored indexed, so we can do fast queries for certain field values. Example: $ journalctl -t icinga2 ICINGA2_FACILITY=ApiListener -n 5 Syslog compatiblity is ratained because good old tag, severity and facility is stored along, and systemd can forward to syslog daemons.
