Here are simple steps to install Datadog's agent on FC17. These steps are meant to be work-arounds until the necessary changes can be brought back into the mainline.
Run the one-liner from our agent page
Change the repository in /etc/yum.repos.d/datadog.repo to have a baseurl of:
baseurl = http://yum.datad0g.com/rpm/
in order to pull the latest agent builds.
Download python-tornado-2.3-1.fc17.noarch.rpm
curl -L "https://github.com/DataDog/dd-agent-deps/blob/master/python-tornado/python-tornado-2.3-1.fc17.noarch.rpm?raw=true" \
> python-tornado-2.3-1.fc17.noarch.rpm
sudo yum localinstall python-tornado-2.3-1.fc17.noarch.rpm
And restart the agent.
sudo service datadog-agent restart
The crux of the issue is that the agent requires Tornado to run. Older RedHat derivatives did not include recent tornado packages (if at all) so we distribute our own packaged version, python-tornado 2.3, with a dependency on python and an implicit dependency on python 2.6. FC17 ships with python 2.7 and python-tornado 2.2.1, with a dependency on python 2.7.
Thus setting up our packaged version python-tornado on FC17 is not picked up by python 2.7, thus the agent does not run out of the box.
