IOInsight

Products:

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?

  • Customers may better tune and size their storage
  • When contacting VMware Support for any vSphere storage issues, including a report from IOInsight can help VMware Support better understand the issues and can potentially lead to faster resolutions.
  • VMware Engineering can optimize products with better understanding of various customers' application behavior.

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.

  • 4vCPU and 2GB VM memory
  • 16GB VM storage space.
  • vSphere 5.5 or above
  • Recommended browsers: Chrome and Safari
  • SSH should be enabled in ESX machines to be monitored

Detailed instructions are provided in the VMware IOinsight User Guide.pdf
