(DEPRECATED)-Display NLM statistics

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The statistics-v1 nfs show-nlm command displays the following statistics about the Network Lock Manager (NLM) on each node in the cluster:

  • Result of the operations (success or failure)

  • Total number of null operations

  • Total number of test operations

  • Total number of lock operations

  • Total number of cancel operations

  • Total number of unlock operations

  • Total number of granted operations

  • Total number of share operations

  • Total number of unshare operations

  • Total number of nmlock operations

  • Total number of freeall operations

  • Total number of all the above operations

This command is designed to be used to analyze performance characteristics and to help diagnose issues.

Note This command requires an effective cluster version earlier than Data ONTAP 9.0. Data for nodes running Data ONTAP 9.0 or later is not collected, and will not be displayed. Use the statistics show`-object`nlm command instead.
