Goal

To provide guidance on collecting analytics data for troubleshooting NFS performance issues

Fix

To review the system's NFS performance and possible problems associated with it, the following statistics from analytics will be useful. These are top level statistics, an Oracle support engineer may request more specific statistics as and when the understanding of any problem deepens.

[Below NFSv4 is used as an example, use the appropriate NFS version as applicable].

Statistics to be collected:

CPU: percent utilization
Cache: ARC accesses per second broken down by hit/miss
Cache: L2ARC accesses per second broken down by hit/miss
Disk: Disks broken down by percent utilization
Disk: I/O operations per second broken down by disk
Disk: I/O bytes per second broken down by disk
Network: interface bytes per second broken down by interface
Protocol: NFSv4 operations per second broken down by type of operation
Protocol: NFSv4 operations per second broken down by share
Protocol: NFSv4 operations per second broken down by size
Protocol: NFSv4 operations per second broken down by offset
Protocol: NFSv4 operations per second broken down by latency

Steps to Follow:

1. In BUI under the "Analytics -> Open Worksheets" page, use the "+" icon to add the above statistics, and save the worksheet with a meaningful name eg: 'nfsperf'. Now close the worksheet and the datasets will continue to run in the background.
2. After the problem has been observed

• Open the saved worksheet
• Synchronize all statistics
• Pause the statistics, zoom in or out as appropriate to cover the time of the problem, as well as up to a certain extent of the normal performance.
• Save and Close the worksheet
• Highlight the worksheet and click the icon to "send a bundle that includes this worksheet", or use the following command to send out the bundle with worksheet:
  

  aksh> analytics worksheets select name=nfsperf sendbundle

3. Provide the name of the file which was uploaded, the date, time and TimeZone of the problem to the support engineer.
