VMware IOInsight is a tool to help people understand a VM's storage I/O behavior. By understanding their VM's I/O characteristics, customers can make better decisions at storage capacity planning and performance tuning. IOInsight ships as a virtual appliance that can be deployed in any vSphere environment and an intuitive web-based UI allows users to choose VMDKs to monitor and view results.
Where does IOInsight help?
IOInsight captures I/O traces from ESXi and generates various aggregated metrics that represent the I/O behavior. The IOInsight report contains only these aggregated metrics and there is no sensitive information about the application itself. In addition to the built-in metrics computed by IOInsight, users can also write new analyzer plugins to IOInsight and visualize the results. A comprehensive SDK and development guide is included in the download bundle.
