Additional context in JSON format |
The panel loads 100 entries at a time by default. Click Load more at the bottom to fetch the next page. The total count is shown above the table.
IP addresses
The client IP is read from the X-Forwarded-For header. When TREK is behind a reverse proxy, set TRUST_PROXY=true so the header is trusted and the real client IP is recorded. Without this setting, the proxy's own IP is logged instead. See Environment-Variables.
Log file
In addition to the database, audit events are written to a plain-text log file:
- Path:
./data/logs/trek.log
- Rotation: rotated when the file reaches 10 MB
- Retention: the 4 most recent rotated files are kept (
trek.log.1 through trek.log.4)
Database retention
Audit entries in the database are never automatically deleted. They accumulate and are paginated in the UI.
