Open Source Python Server Monitoring Tools

Emon is another remote server monitoring application, but this time you are able to start your monitoring in the terminal easily. You do not need to install any applications on the monitoring servers, because Emon uses SSH and /proc directory to get the monitoring data. All you need to do is just configure Emon in XML and create an SSH user. After configuration, you are ready to monitor ping, dns, ports, url, CPU, RAM, SWAP, disk, traffic and log files of multiple servers in the terminal. If something goes wrong, Emon will send email to the admin. Emon is able to send the statistics (dropouts and graphs) to the admin.

WatchTower is a cloud server monitoring and management tool. This is actually a suite of tools that includes a dashboard and associated RESTful web services required for managing the servers and services. The dashboard uses PHP/MySQL (requires php5+), html, and css. It's all open source and very easy to work with and make changes. The client I'm using is included and is written in python. Currently tested with Python 2.4 and 2.6, but should work with any version. I'm not using anything special. My plans also include monitoring/managing of Windows servers through the same python client, but compiled into a working exe, but I will work on that when the Linux client is finished first.
