Try it

``

Specify a port in Bash (Linux and Mac)

#export PORT=8000

Specify a port in Batch (Windows)

#SET /A PORT=8000
npm install
npm run start
`

This starts a web server on the TCP port 8000. Determine your system’s local IP address and add the WebThing to your gateway.

Explanation

* Uptime – Counts the seconds since the last system start (boot).
* Avg. Load – (Unix-like only) Indicates the average load of the last 1, 5, and 15 minutes. On a quad-core a 4 means that the system has not been idle. A value of 2 would roughly translate to the system being 50% busy.
* Free Memory – Indicates free memory in bytes. This goes down as you open more applications.
* Total Memory – Indicates total memory in bytes.
* Free Memory (percent) – Indicates how much memory is free in relation to the total memory. This is a floating point number from 0 to 100.

The average load only works on Unix systems. On a Windows system these values remain at 0. To get a better understanding of the values, read the man page of uptime. You can read this offline on your UNIX system by running man uptime`.
