It is possible for you to use the Rackspace API to retrieve the Running Process List of a Cloud-server on your Rackspace account which has the rackspace cloud-server monitoring agent installed.

TOKEN=mytokengoeshere
server_uuid_here=serveruuidgoeshere
customeridhere=customeridtenantnumberhere

 curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $token" https://monitoring.api.rackspacecloud.com/v1.0/$customeridhere/agents/$server_uuid_here/host_info/processes

Not that difficult to do, really !
