As an experienced sysadmin, website owner or developer, you likely already know Nginx is one of the most ubiquitous, high-performance web servers out there today. However, even Nginx‘s robust architecture can run into issues with growing traffic, changing usage patterns or new deployments. This is why having visibility into key Nginx performance metrics in real-time is critical for any admin.
Enter ngxtop – a brilliant open-source tool for unlocking Nginx analytics across dozens of data dimensions right from your terminal. Let‘s explore the world of insights ngxtop makes readily available.
The Critical Importance of Nginx Visibility
First, some quick background on why Nginx in particular warrants close monitoring. As one of the fastest, most efficient web servers, Nginx now powers over 30% of all websites – serving over 700 million Internet users daily.
However, even with its speed and scalability, Nginx still encounters performance issues, emerging security threats and capacity limitations as modern sites continue pushing the envelope. This graphic shows the potential cascade effect of untreated problems:

- Active Requests
- Total Traffic Volume
- Bandwidth Usage
- Response Times
- Error Code Analysis
- Endpoint Performance
And over 100+ combinable filters to dig deeper! Now let‘s get ngxtop running…
Comprehensive Ngxtop Install Guide
Ngxtop works seamlessly across all major Linux distributions. Here are the detailed steps to follow for Ubuntu, RHEL and CentOS installs:
Ubuntu
- Install pip, python and git using APT if needed…
Verifying Your Setup
Once installation is complete, verify ngxtop is tracking Nginx correctly:
ngxtop --testThis output indicates proper data collection:

ngxtop --filter ‘status > 500‘
ngxtop --filter ‘geoip CN‘ Now let‘s look at building fully custom dashboards…
Building Custom Nginx Dashboards
While ngxtop provides stellar out-of-box insights, you can take things further with customized real-time dashboards reflecting your site‘s unique metrics and KPIs.
Using simple JSON definitions, you can build unlimited dashboard layouts like:

We‘ve only scratched the surfaced of ngxtop‘s robust feature set for Nginx visibility. Here are some additional capabilities as you push further:
Visitor Intelligence – path analysis, traffic source correlation, lifetime value segmentation
Infrastructure Telemetry– CPU utilization, memory, disk activity
Historical Trend Analysis – statistical models for planning and optimization
Alerting Integration – trigger alerts for excessive errors, traffic drops etc.
And much more! Ngxtop evolves daily, so be sure to check their GitHub for the latest developments.
Now over to you! I highly recommend actively trying ngxtop based on your own Nginx use cases and sharing any feedback or results. Looking forward to hearing your experience unleashing the strength of ngxtop!
