+
+## Overview
+
+Kernel Samepage Merging (KSM) is a memory-saving feature in Linux that enables the kernel to examine the
+memory of different processes and identify identical pages. 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. An instance is uniquely identified by a set of labels.
+
+
+
+### Per Kernel Same-Page Merging instance
+
+
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| mem.ksm | shared, unshared, sharing, volatile | MiB |
+| mem.ksm_savings | savings, offered | MiB |
+| mem.ksm_ratios | savings | percentage |
+
+
+
