System Monitoring

When you’re connected to a server via SSH, Reach shows a monitoring bar at the bottom of the terminal. It gives you a quick glance at what’s going on without needing to run htop or top yourself.

What it shows

The monitoring bar displays four things:

• CPU usage (%)
• RAM usage (%)
• Disk usage (%)
• Logged-in users

If your username shows up in the logged-in users list, it’ll have “(you)” next to it so you can spot yourself quickly.

How it works

Stats are polled every 3 seconds by running commands over the existing SSH connection. No agent or extra software needed on the remote server.

Here’s what it reads under the hood:

• CPU: Two snapshots of /proc/stat taken 500ms apart. The difference between them gives the actual CPU usage percentage.
• RAM: Reads /proc/meminfo to get total and available memory.
• Disk: Runs df to get filesystem usage.
• Users: Runs w/who to see who’s logged in.

Since it’s all done through your existing SSH session, there’s nothing to install or configure on the server side.

Per-connection stats

Each SSH connection has its own monitoring data. When you switch between tabs, the monitoring bar updates to show the stats for whichever server you’re looking at.
