Cloud agnostic python based platform for executing code when change happens in your cloud environment. The dev team at DivvyCloud developed a plugin and event system that allows python code to be executed when change occurs in a cloud infrastructure. We do this by continually harvesting the state of the cloud environment and comparing it to the previously known state. Through this comparison we can detect change, that will result in an event being fired and registered plugins being executed. Using this technology, DevOps teams can begin to write python based plugins that autonomously manage their cloud environment.
Because we think this system is very powerful (and very cool), we are thinking about giving it to the open source community. But before we put the energy into getting it all fancied up, we want your feedback. Please come out and watch a demonstration of our Event Driven Infrastructure Platform and let us know what you think.

Temporarily stopping execution in scripts

One of our junior sys admins told me he was trying to figure out how to modify his monitoring script during maintenance windows (the monitoring script is called automatically by the monitoring agent on the box.) I told him to use a "stop file."

At or near the top of your script (a simple bash script,) put a block like this:

if test -f /tmp/do_not_run
then

echo "Ok"
exit 0

fi

Then, during maintenance windows, create the /tmp/do_not_run file and the script will simply exit without attempting to perform any actions against the system. When the maintenance window is over, remove the file and everything goes back to normal.
