 VM insights includes a set of performance charts that target several key [performance indicators](vminsights-log-query.md#performance-records) to help you determine how well a virtual machine is performing. The charts show resource utilization over a period of time. You can use them to identify bottlenecks and anomalies. You can also switch to a perspective that lists each machine to view resource utilization based on the metric selected.
