Setting Up Fiveruns Manage
The Fiveruns Manage service reached end of life in August 2009 and is now closed. Brightbox replaced it with New Relic RPM. See the Brightbox blog post for more details.
You can uninstall the Fiveruns manage daemon with this command line:
yes | sudo /usr/local/fiveruns/manage/uninstall.sh
And you need to remove the plugin from your Rails app, or it will continue to write stats files and eventually fill up your disk.
