At the time of writing; Rackspace has docs on how to create an alert from dashboard :

It is very easy to create an alert from the graphical user interface. It will report that monitoring agent is not installed. It will not be able to show any graphs at this step.
Install Rackspace Monitoring Agent (Free) on Cloud Server : Work From SSH to Complete
SSH to your Server, copy paste this for Ubuntu 14.04 server :
1 | sudo sh -c 'echo "deb http://stable.packages.cloudmonitoring.rackspace.com/ubuntu-14.04-x86_64 cloud monitoring main" > /etc/apt/sources.list.d/rackspace-monitoring-agent.list' |
For other OS, you should read the official doc :
1 | http://www.rackspace.com/knowledge_center/article/install-the-cloud-monitoring-agent#Ubuntu |
If you run sudo apt-get update command at this step; you will face error. Because you need to add this key before :
1 | curl https://monitoring.api.rackspacecloud.com/pki/agent/linux.asc | sudo apt-key add - |
Now you can run :
1 2 3 | sudo apt-get update sudo apt-get upgrade sudo apt-get install rackspace-monitoring-agent |
Now, we need to setup the monitoring agent and start it :
1 2 3 4 5 6 | sudo rackspace-monitoring-agent --setup # use your username in lowercase and API as password # start the agent sudo service rackspace-monitoring-agent start # you can edit the config from command line # nano /etc/rackspace-monitoring-agent.conf.d/main_disk_check.yaml |
Obviously – you can set or unset the daemon as autostart to reboot.
