Netdata

Netdata is an open-source, real-time infrastructure monitoring platform trusted by engineers at thousands of companies worldwide. With over 78,000 GitHub stars and 500 million Docker Hub pulls, it is one of the most widely adopted self-hosted monitoring solutions available. The agent collects thousands of metrics per second from operating systems, containers, databases, web servers, and cloud services — making them immediately visible in interactive dashboards with 1-second resolution, without any configuration work beyond deployment.

Common Use Cases

DevOps and platform engineers use Netdata to monitor VPS health around the clock — tracking CPU spikes, memory pressure, disk I/O saturation, and network throughput in real time, catching resource exhaustion before it causes application failures. Development teams deploy Netdata alongside their application stacks to correlate infrastructure metrics with application behavior, using the built-in Docker container monitoring to track resource consumption per service. SRE and on-call teams rely on Netdata's pre-configured alert library to receive immediate notifications when a database connection pool fills up, disk usage crosses a threshold, or a service stops responding — without spending hours writing alert rules. System administrators managing multiple services on a single VPS use the auto-discovery feature to get full visibility into every running process, service, and container within seconds of deployment, with no per-service configuration required.

Key Features

• 1-second metric granularity captures transient spikes that coarser polling intervals miss
• 800+ integrations auto-discovered at startup — MySQL, PostgreSQL, Redis, Nginx, Apache, and more
• Machine learning anomaly detection trains a model per metric and surfaces unusual patterns automatically
• Docker container monitoring via socket — CPU, memory, network I/O, and disk per container
• Hundreds of pre-configured alerts covering OS, database, and application failure patterns
• Notification integrations for Slack, PagerDuty, email, Telegram, Discord, and 30+ other channels
• Interactive dashboards with drill-down, zoom, and metric correlation built in
• Log monitoring from /var/log with real-time parsing and pattern detection
• Zero external dependencies — metrics stored locally with configurable retention
• Optional Netdata Cloud integration for multi-node views and centralized alerting

Why deploy Netdata on Hostinger VPS

Running Netdata on a Hostinger VPS gives you complete visibility into your infrastructure without sending metrics to a third-party cloud service. All data stays within your VPS, satisfying privacy and compliance requirements that cloud-hosted monitoring services cannot meet. The single-container deployment with named volumes means zero database administration overhead — Netdata manages its own time-series storage, and the retention window scales with your available disk space.

A Hostinger VPS provides the dedicated CPU and memory headroom Netdata needs to maintain 1-second collection across hundreds of metrics without competing with the applications it monitors. As your infrastructure grows, Netdata scales with it: adding more services on the same VPS means more auto-discovered integrations, not a larger monitoring bill. For teams running multiple applications on a single VPS, Netdata's per-container and per-process breakdown makes it straightforward to attribute resource usage and identify which workload is responsible for a capacity event. Optional Netdata Cloud connectivity lets you aggregate metrics from multiple VPS instances into a single view when your infrastructure expands beyond a single node.
