Audit source (source_type=audit), off until enabled in Settings > Sources:
- follows /var/log/audit/audit.log (path configurable, AUDIT_LOG), with
rotation (end of audit.log.1 read first) and an offset checkpoint in
/data/audit-state.json; last AUDIT_BACKFILL (1h) read on first enable
- groups the records of an event by msg=audit(time:serial), closed on EOE,
after 2 s without a record, or once the log has moved 2 s past it
- fields audit_type, audit_serial, auid, user (enriched name, host
/etc/passwd or uid), exe, res, key, audit_raw; app = audit_type, host =
node= / AUDIT_HOST / /host/etc/hostname; summary "who: what [key] →
result"; warning when res=failed / success=no, info otherwise
- hexadecimal values (proctitle, cmd, exec arguments…) decoded
Internal logs (source_type=logstream, host=logstream, app=component):
- logEvent() for VictoriaLogs unreachable / back, lost batches, spooled
batches refused, syslog listener errors, Docker API and container
streams lost, failing sources, start and stop
- on by default from warning; switch and minimum level in Settings >
Sources (/data/selflog.json)
- bounded queue, never waits for the Store, same event at most once per
30 s with a count of the repeats: a failing Store cannot loop
UI: violet (audit) and turquoise (LogStream) left edge and tint, AUDIT /
LS badge before the app, raw audit record under the summary (folded in
compact density until the row is opened), Audit and LogStream in the
source filter, FR/EN translations. docker-compose: optional
/var/log/audit, /etc/passwd and /etc/hostname mounts. README (EN/FR):
host prerequisites (log_group, ACL for UID 10001).

New source in Settings > Sources, off by default: reads the kernel ring
buffer of the host through /dev/kmsg, dates records from the boot time and
resumes after the last sequence number of the same boot (no duplicates on
restart). Missing device or denied access is shown in the UI, retried every
10 s. docker-compose.yml and .env.example document the device and the
kernel.dmesg_restrict / CAP_SYSLOG options.

New source, off by default and switched in Settings > Sources, that
collects the system logs of the machine hosting the stack:
- reads the systemd journal files directly (pure Go reader, no
journalctl in the image), from /var/log/journal and /run/log/journal
mounted read-only under /host;
- falls back to following the text files of /var/log (syslog,
messages, *.log) on hosts without journald;
- positions saved in /data/hostlogs-state.json, HOST_LOGS_BACKFILL
read when the source is turned on;
- source_type "host", selectable in the Source filter;
- compose mounts and group_add (HOST_LOGS_GID, adm by default), docs.

The histogram above the list becomes a configurable timeline:
- Scale linear / sqrt (default) / log, height S/M/L, bars or area.
- Colors: stacked by severity (error+, warning, the rest), intensity
against the median of the window (calm, burst >3x, anomaly >10x), or
none; colors are CSS variables with light and dark values.
- Vertical graduations on round local times (hh:mm:ss, hh:mm, dd/mm).
- Tooltip: interval bounds, total and detail per severity.
- Division automatic (~100 intervals) or fixed (1 s to 1 day), capped at
300 intervals by the server; intervals aligned on the local time zone.
- Refresh off / 5 s / 15 s / 30 s / 1 min / at each new interval. In
live mode the last interval is incremented from the SSE stream and the
timeline reloads at each new interval; paused while the tab is hidden.
- Click a bar to zoom on its interval, drag to zoom on a selection: the
list, export and counters follow through new from/to parameters.
The timeline now runs on the server clock (bounds and "now" come from
/api/histogram): the axis was drawn from the browser clock and refreshed
every 30 s only, so a clock difference with the server or a hidden tab
left it behind the logs.
/api/histogram returns interval indexes with the count per severity; the
division logic lives in histogram.go with table-driven tests.

- docker.go follows every running container through the Docker API
(events + logs with follow), resumes after a restart from the last
position saved in /data/docker-state.json, reads DOCKER_BACKFILL (1h)
of history for new containers, strips terminal color codes and guesses
the severity from the line (JSON, logfmt, [ERROR], ERROR ...).
- Logs carry source_type=docker, container, container_id, image,
compose_project, compose_service and stream; host is the Docker host.
- Settings > Sources: one switch per container (grouped by compose
project), enable/disable all, follow new containers automatically.
Choices are saved per compose service in /data/docker.json.
- Source filter (syslog / docker) in the filter bar and the live view.
- docker-compose: read-only docker-socket-proxy; Logstream and the proxy
are labelled logstream.exclude=true and never collected.
