Scruffy

A simple script to continuously test and report the quality of your DSL connection.

Why

My ISP is full of sh*t, and doesn't run automated tests. Or if they do, they're programmed by people that have trouble counting past ten because they run out of fingers.

How it works

Scruffy checks and logs:

1. Speed via speedtest;
2. Local IP details via ifconfig
3. ADSL Line stats via SNMP from your ADSL router

Setup

1. Log into your router's configuration panel and enable SNMP.

2. Do the following:

   sudo ln -s /absolute/path/to/project /usr/local/bin
   cd /usr/local/bin/scruffy
   bundle install
   whenever --update-crontab
   

Output

Every 30 minutes, scruffy stores the result at logs/YYYY-MM.log

TODO

1. Use SQLite to store the log instead of a file.
2. Show analytics via a webserver
3. Sync backup db to s3 periodically
