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 viewing more than one logfile).

Build
Get pre-requisites
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 to monitor a couple of Linux logfiles.
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. Here are some to try:
/var/log/syslog
/var/log/auth.log
/var/log/lastlog
/var/log/dmesg
/var/log/kern.log
/var/log/boot.log
