It then merges these identical pages into a +single page that the processes share. This is particularly useful for virtualization, where multiple virtual +machines might be running the same operating system or applications and have many identical pages. + +The collector provides information about the operation and effectiveness of KSM on your system. + + + + +This collector is supported on all platforms. + +This collector only supports collecting metrics from a single instance of this integration. + + +### Default Behavior + +#### Auto-Detection + +This integration doesn't support auto-detection. + +#### Limits + +The default configuration for this integration does not impose any limits on data collection. + +#### Performance Impact + +The default configuration for this integration is not expected to impose a significant performance impact on the system. + + +## Metrics + +Metrics grouped by *scope*. + +The scope defines the instance that the metric belongs to.
