rtop is a
simple, agent-less, remote server monitoring tool that works over SSH.
It doesn’t required any other software to be installed on remote
machine, except openSSH server package & remote server credentials.
rtop is written in golang, and requires Go version 1.2 or higher. It can able to monitor any modern Linux distributions. rtop can connect remote system with all possible way like using ssh-agent, private keys or password authentication. Choose the desired one and monitor it.
It works by establishing an SSH session, and running commands on the remote server to collect system metrics such as CPU, disk, memory, network. It keeps refreshing the information every few seconds, like top command utility.
Add the refresh interval manually for better monitoring. I have added
10 seconds refresh interval instead of default one (default: 5).
