 Resources generate metrics that are used in autoscale rules to trigger scale events. Virtual machine scale sets use telemetry data from Azure diagnostics agents to generate metrics. Telemetry for Web apps and Cloud services comes directly from the Azure Infrastructure. 
 
 Some commonly used metrics include CPU usage, memory usage, thread counts, queue length, and disk usage. See [Autoscale Common Metrics](autoscale-common-metrics.md) for a list of available metrics.
