What Is Netdata?

Netdata is a real-time monitoring agent that collects thousands of metrics per second with zero configuration. It provides beautiful dashboards out of the box and uses minimal resources.

Installation

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

Netdata starts automatically and is accessible at http://your-server:19999.

What It Monitors (Automatically)

CPU usage per core, system, user, iowait
RAM, swap, and memory pressure
Disk I/O, latency, and space usage
Network bandwidth, packets, errors per interface
Process trees and per-process resource usage
System load, entropy, uptime

Application Monitoring

Netdata auto-detects and monitors common applications:

Web servers: Nginx, Apache, LiteSpeed
Databases: MySQL, PostgreSQL, Redis, MongoDB
Containers: Docker, Podman, LXC
System: systemd services, cgroups

Alerting

Edit /etc/netdata/health.d/ to customize alerts:

alarm: disk_space_usage
on: disk.space
lookup: max -1s foreach *
units: %
every: 10s
warn: $this > 80
crit: $this > 90
info: disk space usage is $this%

Restrict Access

# /etc/netdata/netdata.conf
[web]
    bind to = 127.0.0.1
    allow dashboard from = localhost 10.0.0.*

Resource Usage

Netdata is designed to be lightweight: typically 1-3% CPU and 100-200 MB RAM. Metrics are stored in RAM by default with configurable retention periods.
