Excellent Utilities: lnav – the log file navigator

This is the second in a new series highlighting best-of-breed utilities. We’ll be covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. For this article, we’ll put lnav under the spotlight. lnav is a curses-based utility for viewing and analyzing log files. The software is designed to extract useful information from log files, making it easy to perform advanced queries. Think of lnav as an enhanced log file viewer. For many years system and kernel logs were handled by a utility called syslogd. Most Linux-based operating systems have since moved to systemd, which has a journal. That’s a giant log file for the whole system. Various software and services write their log entries into systemd’s journalctl. lnav can consume the JSON version of journalctl’s output. And it supports a wide range of other log formats. For systems running systemd-journald, you can also use lnav as the pager. We included a couple of log analyzers in our Essential System Tools feature. And lnav wouldn’t be totally out of place in that feature. lnav is optimized for small-scale deployments.
