There are three types of Enterprise Monitoring Points (EMPs): physical, virtual, and software. Physical monitoring points (models m* and r*) are hardware devices used for general monitoring, monitoring in wireless environments, and monitoring where high performance is required. Virtual monitoring points (model v35) are virtual machines that run in KVM or VMware virtual environments. They are used for general monitoring tasks, and are uniquely suited to virtual environments. Software monitoring points (model s35) are run as an application in a Windows environment. They can only be used for Delivery monitoring. A full capabilities comparison of each model can be found on the Monitoring Point Feature Comparison page. Deployment recommendations can be found on the Deploying Your Monitoring Point page.
