nerdlog

nerdlog [options] [hosts...]

nerdlog is a fast, remote-first, multi-host TUI log viewer with an interactive timeline histogram, inspired by Graylog and Kibana but without the bloat. It queries logs from multiple remote machines simultaneously over SSH, filters them by time range and patterns, and draws a visual timeline.The tool reads system logs from /var/log/messages, /var/log/syslog, or journalctl, and uses standard GNU tools (bash, awk) on the remote side for filtering and histogram generation. No central server or agent installation is needed.

Requires SSH access to target hosts. Remote hosts must have bash and awk available.

nerdlog was created by dimonomid and is written in Go using the tview library. It supports Linux, FreeBSD, macOS, and Windows (client only).
