Lnav Who Accessed What And When

A user connected at 03:14. Another pulled sensitive data at 03:16. The error that followed revealed a bigger problem. You know something happened, but not who, what, or when—until you open lnav.

Lnav Who Accessed What And When is not guesswork. It’s command-line clarity. Lnav ingests your logs, indexes them, and lets you slice timelines with surgical precision. You see the exact query that ran, the session that triggered it, and the sequence of events leading up to the breach, crash, or anomaly.

Start by loading your log files:

lnav /var/log/*.log

The data becomes searchable instantly. Use the / key to search for usernames, IP addresses, or operation codes. Filter by timestamp to pinpoint activity windows. Drill down with SQL mode (;) to correlate user actions across multiple services.

For access tracking, the key is correlation. Import database logs, API gateway logs, and application logs into one Lnav session. Now you have a unified view: user ID mapped to API call mapped to DB query mapped to write operation. The "who,""what,"and "when"compress into a single pane of chronological truth.

Performance matters. Lnav parses on the fly, supports compressed files, and lets you bookmark critical patterns. Color-coded fields make anomalies obvious—failed logins in red, admin actions in yellow, data exports in cyan.

When audits arrive, exporting results is trivial:

:write-access log_report.csv

You have a defensible record of every action taken, without relying on fragmented tools or blind trust.

Stop guessing. Start knowing. See who accessed what and when with Lnav in minutes. Then push it further—connect it with hoop.dev and watch real-time access intelligence come alive in your environment today.
