Monitoring Server Anytime from Your Phone with Termius

Monitoring Server Anytime from Your Phone with Termius

Managing servers doesn’t always require a laptop. While traveling, with just your phone and the Termius app, you can check your server’s condition in seconds. This article guides you through preparation, basic commands, and tips for securing the connection – concise and ready to put into practice.

Initial Preparation: Install Termius & Add a Server

Download Termius from the Play Store (Android) or App Store (iOS), then open the app. To add your first server:

1. Tap the “+” icon or the New Host button.
2. Fill in the following details:
   • Alias – a name to identify the server, e.g., Web Production.
   • Hostname – the server’s IP address or domain.
   • Port – typically 22 (SSH default).
   • Username – the user used to log in (e.g., root or ubuntu).
3. Choose an authentication method. You can directly fill in the password in the available field, but for better security, use an SSH key (discussed in the Tips section). Save the configuration, then tap the host to connect.

Basic Commands to Monitor Server Capacity

Once connected, you’ll enter a standard terminal session. Here are the most commonly used commands to check the server’s “health.”

CPU & Memory

Use top for an interactive view, or htop if it’s installed (easier to read on a small screen). If you just want a one-time snapshot without interaction, run:

top -bn1 | head -20

This command displays a summary of running processes along with CPU and memory percentages – great for a screenshot of the server’s status.

Disk Usage

To view the capacity of all partitions at a glance:

df -h

The -h flag shows sizes in a human-readable format (MB/GB).
If you need to find out which folder is the heaviest, point to the suspected directory:

du -sh /var/*

The command above shows the total size of each folder in /var. Replace the directory as needed.

Termius Snippets: One-Tap Monitoring

Termius has a Snippets feature that lets you save one or more commands and run them with a single tap. This feature is very helpful for routine checks.

Creating a Resource Check Snippet

Combine several commands into one snippet to display CPU, memory, and disk information at once. Example snippet content:

echo "=== CPU & Memory ==="
top -bn1 | head -15
echo ""
echo "=== Disk Usage ==="
df -h /
echo ""
echo "=== Top Processes ==="
ps aux --sort=-%mem | head -6

How to save it:

• Open Snippets from the Termius main menu.
• Tap “+”, give it a name (e.g., Quick Server Check), then copy the command sequence above into the code field. Save.
• When connected to the server, this snippet can be called from the snippet menu in the toolbar. All commands will run sequentially and the results will be displayed immediately.

Another advantage: snippets sync across devices if you log in with a Termius account, so create once, use anywhere.

Security & Stable Connection Tips from Your Phone

Monitoring from a phone is prone to unstable connections or security risks if you rely only on a password. These two steps will make your routine safer and more comfortable.

Use SSH Key Authentication (More Secure)

• In Termius, open Keychain (the key storage). You can generate a new key pair directly in the app (RSA 2048-bit is sufficient).
• Copy the generated public key. Paste its content into the ~/.ssh/authorized_keys file on the server (if it doesn't exist, open a text editor on the server and add it).
• Go back to the host settings in Termius, and under Authentication, select the key you just created instead of a password.

This way, every SSH connection relies solely on the private key stored securely on your phone.

Dealing with Unstable Connections or Timeouts

Cellular signal can sometimes be intermittent. To prevent your SSH session from dying mid-check:

• Edit the saved host, find the Keepalive or TCP Keepalive option. Enable it and set the interval to around 30–60 seconds. This will periodically send empty packets so the server considers the connection “alive.”
• If the server supports it, consider using the Mosh protocol (mobile shell) available in Termius. Mosh is more tolerant of unstable networks, but it must be installed on the server side first (sudo apt install mosh).

With key security and proper connection handling, you can monitor the server anytime without worry.

Managing servers from your palm becomes much more practical thanks to Termius. The combination of basic commands, customized snippets, and key authentication keeps you productive even with just a phone. We hope this guide makes your routine easier.
