An open source and free SNMP bandwidth monitor
Version: 0.4 DevSniff is a SNMP monitor tool that can help you to retrieve information of monitored devices or get error report when something is going wrong by phone messages.
Operating System: Mac OS X
There are two parts of Sniff. The main part is written as a Django application that takes care of most tasks on server side while the other is just a simple client running on Nokia's Symbian S60 platform for handling message-related tasks.
You can run Sniff's main application on any operating system that comes with support for the Python programming language such as Mac OS X, Windows, and Linux.
However, the connection between the Sniff's main part(server) and the other (smartphone) is achieved by Bluetooth. So both of them must support Bluetooth as well.
