How to install Netdata for real-time monitoring

Updated 7/20/2026

Netdata is a monitoring tool that displays CPU, RAM, disk, network and dozens of other metrics in real time, through a fast web interface.

1. Install

wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh
sh /tmp/netdata-kickstart.sh

2. Access the interface

Netdata listens on port 19999 by default:

http://SERVER_IP:19999

3. Secure access

Do not leave the port publicly open. Put Netdata behind a reverse proxy with authentication and HTTPS (see Nginx as a reverse proxy), or allow the port only from your IP with the firewall.

4. What to watch

CPU or RAM spikes that coincide with slowness.
Disk filling up, see disk space monitoring.
Unusual network traffic.

Low footprint

Netdata is lightweight and runs well even on small plans. To monitor several servers in one place, see the Beszel app.
