Terminal Dashboard for Monitoring Log Files

logtail is a Rust command line program which displays the last few lines of a one or more logfiles in the terminal. It watches for changes and updates the display in the manner of tail -f.

The command is written in Rust and uses tui-rs to create the terminal UI, and linemux to monitor the logfiles.

It is not particularly clever and was written as a learning project, but is a useful little utility.

Supports Linux only as far as I know, but it's worth testing out on MacOS and Windows. If it doesn't work I don't think it will be hard to get working on those platforms.

Starting from logtail I'm working on a SAFE Network Vault Dashboard (vault-dash) which will provide metrics based on vault logfiles. In fact vault-dash was the original goal but I saw value in splitting out logtail-dash as a separate utility.

Install from crates.io

cargo install logtail

Usage

In the terminal type the command and the paths of one or more logfiles you want to monitor. For example:

logtail /var/log/auth.log /var/log/kern.log

When the dashboard is active, pressing 'v' or 'h' switches between horizontal and vertical arrangments (when vieing more than one logfile).

For more information:

logtail --help

Build

Get pre-requisites

Get Rust: see: https://doc.rust-lang.org/cargo/getting-started/installation.html

Build logtail

git clone https://github.com/theWebalyst/logtail-dash
cd logtail-dash
cargo build

Quick Test

Here's a couple of useful commands to build and run logtail-dash using Linux logfiles rather than actual vault files.

Open two terminals and in one run logtail-dash with:

RUSTFLAGS="$RUSTFLAGS -A unused" cargo run /var/log/auth.log /var/log/kern.log

In a second terminal you can affect the first logfile by trying and failing to 'su root':

su root </dev/null

You can use any logfiles for this basic level of testing.
