Few users have asked to the owner of this blog to write about NodeQuery. There is its competitor, NixStats, reviewed in this blog. Finally, here’s the article you might have been waiting for. Let’s monitor our server with NodeQuery.
Wait!! What is it exactly? To cut long story short, NodeQuery is a web-based app provideing a lightweight and easy to use linux server monitoring service. This service is currently in Beta stage offering free plan with up to 10 servers to monitor freely. Let’s take a look at its key features :
- Quick and easy setup – the service agent is designed to be easy-to-use and is compatible for major linux distribution. Yet, it is also easy to remove.
- Detailed metrics – their system will periodically store various system including system load, RAM Usage, Networks performance, etc.
- Email notifications – Right at the minute user’s servers stop sending data or may be using more resources than the custom threshold set in the dashboard, NodeQuery will send in-depth notification.
- Public API – NodeQuery’s intelligent API allows users to query almost every data of their servers’ data.

What’s the discrepancies between NodeQuery and NixStats :
Meanwhile as far as I can notice, NodeQuery offers only system performance monitoring while NixStats also provides website uptime monitoring in addition to performance monitoring. Moreover, while NixStats offer public stats page, NodeQuery does not (may be yet).
Anyway, I really like the simplicity of NodeQuery’s user interface and the way its display the data. How to setup NodeQuery monitoring agent on your server?
