To cut long story short, NodeQuery is a web-based app  providing 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.

Looks nice monitoring service.
Though I prefer netdata as it's free, open source and comes with many features..

Haha nodequery look like a good service but i'll prefer netdata or a custom one for system performance and for downtimes i think a cron job will do the work.

Good recommendation, NodeQuery is also a free service.

This is completely on your personal preferences. Mostly people don't need in-depth monitoring. They only need basic performance reports like Network usage, Network Latency, Average Load, RAM and Disk usage etc. And I think NodeQuery will be a very good choice for them.

For basic performance graph i think control panel is best option as you don't need to rely on third party as VPS control panels also shows basic usage and performance.

Yeah free is the best way to go especially if your testing it out.
