+CloudStack Nagios uses the CloudStack API to collect information about system vm's and resources.
 
 The following checks are supported:
   * system and network checks for virtual routers
   * storage pool capacity checks
   * global zone capacities
 
 ## Prerequisites
 
-  * Cloudstack Root Admin keys have to be used.
-  * In order to connect to system VMs the private ssh key found on the Cloudstack management server under /var/lib/cloud/management/.ssh/id_rsa are required.
-  * The system vms must be reachable on the Cloudstack Management Network over SSH (default port 3922) from the nagios server executing the checks (check with 'ssh -i /var/lib/cloud/management/.ssh/id_rsa -p 3922 <router_mgmt_ip>').
