+= Local Storage Operator Metrics
+
+{product-title} provides the following metrics for the Local Storage Operator:
+
+* `lso_discovery_disk_count`: total number of discovered devices on each node
+
+* `lso_lvset_provisioned_PV_count`: total number of PVs created by `LocalVolumeSet` objects
+
+* `lso_lvset_unmatched_disk_count`: total number of disks that Local Storage Operator did not select for provisioning because of mismatching criteria
+
+* `lso_lvset_orphaned_symlink_count`: number of devices with PVs that no longer match `LocalVolumeSet` object criteria
+
+* `lso_lv_orphaned_symlink_count`: number of devices with PVs that no longer match `LocalVolume` object criteria
+
+* `lso_lv_provisioned_PV_count`: total number of provisioned PVs for `LocalVolume`
+
+To use these metrics, be sure to:
+
+* Enable support for monitoring when installing the Local Storage Operator.
+
+* When upgrading to {product-title} 4.9 or later, enable metric support manually by adding the `operator-metering=true` label to the namespace.
