Hey guys, so today I though I would give an overview of what NetData is and how I utilise it for real-time statistics collection of my Linux based devices in in my home network/lab.
What is NetData?
NetData is a real-time statistics and health monitoring solution which allows many different areas of your device to be monitored for data and also health. A benefit of this data collection is the ability for each statistic to be referenced via the dashboard.js script. This script can be used to visualise the data which NetData collects and output it in a custom html based web page. You may want to do this due to the default dashboard showing every metric that is collected in one view.
Dashboards
The following screenshot is the default page which has all the raw data viewable.

This view can be pretty hectic so I wanted to create something more precise and straight to the information I wanted to see. So I used bootstrap to create the below!

NetData Integrations
NetData can tie in with software which is installed on the host (see this infographic for a rundown of supported software) as you can see in the above screenshot.
An example of this in use is the ability to see how many current session are active on my NGINX reverse proxy.

This data is being gathered by the NGINX “web_log_nginx.response_statuses” integration. Pretty cool!
As well as this you can also monitor separate docker container metrics such as CPU!

Disk Monitoring
NetData can also tie in with storage data statistics such as free/used space per drive or in my case a mounted volume via fstab.

If you would like to take a look at how i created this dashboard see the file below.
Thanks guys! Any questions leave a comment!
