In any virtualization environment that uses shared storage for virtual machines, it is imperative that the storage perform adequately in order to maintain optimum performance. SolarWinds has released a free tool to monitor the latency between the virtual machine and its storage that it runs on. Here are some of the highlights of this tool:

• Get at-a-glance insight into host to datastore connections with the worst response times, and the busiest VMs using those connections
• See a breakdown of the datastore including type and device versus kernel latency
