Server Monitor Dashboard using Pusher API

A simple dashboard to monitor your server's CPU, Memory and Disk Usage (Auto-refreshed every 15 seconds)

How does it work ?

1. A python script reads the CPU, Memory, Disk usage on the server and sends it to Pusher API
2. You view the results using a simple HTML/js file which pulls the data from Pusher API
3. The results are only accessible using your secure Pusher API key

Advantages of this method

1. No need to open up ports, configure security/firewall rules, setup https, encryption etc... on your server
2. You can view the results using a simple HTML file on your desktop/laptop/mobile phone.

Pre-requisite

Sign-up for an account on https://pusher.com/ . Please make a note of your APP_ID, KEY, SECRET, CLUSTER values from the pusher dashboard. Free version allows you to send up to 200K messages a day. This is enough for monitoring 1 server every 15 seconds.

TODO

The easiest way to run the server process in the background is as follows tmux new-session -s server-push python3 server_push.py Then press CTRL-b , and then press d This will detach you from tmux session To reconnect back to the session, use tmux attach Pressing CTRL-c inside the tmux session will kill the process and stop broadcasting the values.
