Display statistics for ONTAP NFS SVMs
You can display NFS statistics for storage virtual machines (SVMs) on the storage system to monitor performance and diagnose issues.
- 
Use the
statistics catalog object showcommand to identify the NFS objects from which you can view data.statistics catalog object show -object nfs* - 
Use the
statistics startand optionalstatistics stopcommands to collect a data sample from one or more objects. - 
Use the
statistics showcommand to view the sample data. 
The following example shows performance data for the NFSv3 protocol.
The following command starts data collection for a new sample:
vs1::> statistics start -object nfsv3 -sample-id nfs_sample
The following command shows data from the sample by specifying counters that show the number of successful read and write requests versus the total number of read and write requests:
vs1::> statistics show -sample-id nfs_sample -counter read_total|write_total|read_success|write_success
Object: nfsv3
Instance: vs1
