- Gathers NFS statistics to investigate problems when you deploy a new configuration, such as a new NFS server or network, in the NFS environment.
- Provides statistics about the success and failure of NFS operations.
- Publishes latency statistics about the success and failure of NFS operations.
- Troubleshoots NFS performance issues.
