This tutorial walks through installing and configuring Netdata on a Linux VPS.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prerequisites<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>A Linux VPS (Ubuntu 20.04\/22.04\/24.04 or Debian 11\/12 recommended)<\/li><li>Root or sudo access<\/li><li>At least 512 MB RAM (1 GB+ recommended for production servers)<\/li><li>A firewall that allows port 19999 (or configure a reverse proxy)<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you don&#8217;t already have a VPS, <a href=\"https:\/\/virtualserversvps.com\/\">compare VPS providers on our comparison page<\/a> to find one that fits your monitoring needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Install Netdata<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The easiest way to install Netdata is using the automated one-line installer, which detects your operating system and handles all dependencies:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>bash &lt;(curl -Ss https:\/\/my-netdata.io\/kickstart.sh)<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This script will:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Detect your OS and package manager<\/li><li>Install all required dependencies<\/li><li>Download the latest Netdata release<\/li><li>Compile and install Netdata<\/li><li>Start the Netdata service and enable it on boot<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Alternative: Install via Package Manager<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On Ubuntu\/Debian, you can also install Netdata directly from the official repository.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Verify Netdata is Running<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After installation, verify that the Netdata service is active:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo systemctl status netdata<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">You should see output indicating the service is <strong>active (running)<\/strong>. Netdata binds to <code>localhost:19999<\/code> by default.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Configure Firewall Access<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To access the Netdata dashboard from your browser, you need to expose port 19999 through your firewall. For security, restrict access to your IP address only.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: Exploring the Netdata Dashboard<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Open <code>http:\/\/YOUR_VPS_IP:19999<\/code> in your browser. The dashboard provides real-time per-core CPU utilization, memory usage, disk I\/O operations, and network bandwidth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 5: Setting Up Alerts and Notifications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Netdata comes with 200+ pre-configured alerts. To receive notifications via email, Slack, Discord, Telegram, or PagerDuty, edit the health notification configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 6: Enable Long-Term Metrics Storage<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">By default, Netdata stores about 2 hours of metrics in memory. For historical analysis, configure the database engine to store weeks or months of data.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 7: Setting Up Netdata Cloud (Optional)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For monitoring multiple VPS instances from a single dashboard, register your nodes with Netdata Cloud. This enables centralized monitoring across all your VPS instances.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Metrics to Watch<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Metric<\/th><th>Warning Threshold<\/th><th>Critical Threshold<\/th><th>What to Do<\/th><\/tr><\/thead><tbody><tr><td>CPU Usage<\/td><td>&gt;80% sustained<\/td><td>&gt;95% sustained<\/td><td>Upgrade vCPU allocation or optimize processes<\/td><\/tr><tr><td>RAM Usage<\/td><td>&gt;85%<\/td><td>&gt;95%<\/td><td>Add swap or increase RAM allocation<\/td><\/tr><tr><td>Disk I\/O Latency<\/td><td>&gt;10ms<\/td><td>&gt;20ms<\/td><td>Check for disk contention, upgrade to NVMe<\/td><\/tr><tr><td>Disk Usage<\/td><td>&gt;80% full<\/td><td>&gt;90% full<\/td><td>Clean up logs, resize disk, or offload data<\/td><\/tr><tr><td>Network Errors<\/td><td>&gt;0.1% packet loss<\/td><td>&gt;0.5% packet loss<\/td><td>Check network interface, contact provider<\/td><\/tr><tr><td>TCP Retransmits<\/td><td>&gt;0.1% of packets<\/td><td>&gt;0.5% of packets<\/td><td>Investigate network congestion or hardware issues<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Netdata transforms your VPS from a black box into a fully transparent system where every metric is visible in real-time. With the installation and configuration steps in this guide, you now have a professional-grade monitoring setup that alerts you to anomalies before they become outages.
