D Language bindings and high level wrapper for the systemd journal logging service (journalctl)

alpha status

rather than grep /var/log/messages, systemd interface makes it easy to filter by field and period of interest. metadata is stored along with regular log messages, which reduces the ability of bad actors to spoof logs

Description

systemd-journald is a system service that collects and stores logging data. It creates and maintains structured, indexed journals based on logging information that is received from a variety of sources:

Kernel log messages, via kmsg

Simple system log messages, via the libc syslog(3) call

Structured system log messages via the native Journal API, see sd_journal_print(4)

Standard output and standard error of system services

Audit records, via the audit subsystem
The daemon will implicitly collect numerous metadata fields for each log messages in a secure and unfakeable way. See systemd.journal-fields(7) for more information about the collected metadata.

Log data collected by the journal is primarily text-based but can also include binary data where necessary. All objects stored in the journal can be up to 2^64-1 bytes in size.
