Goal

To provide guidance on collecting analytics data for troubleshooting CIFS performance issues. To review the system's CIFS performance and any problems associated with it, collecting the following statistics from analytics will be useful. These are top level statistics, an Oracle Support engineer may request more specific statistic as and when understanding of any problem deepens.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance Community

Solution

Statistics to collect:

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: CIFS operations per second broken down by type of operation
Protocol: CIFS operations per second broken down by share
Protocol: CIFS operations per second broken down by size
Protocol: CIFS operations per second broken down by offset
Protocol: CIFS operations per second broken down by latency

Steps to follow:

1. In the BUI under the "Analytics -> Open Worksheets" page, use the "+" icon to add the above statistics, and save the worksheet with a meaningful name eg: 'cifsperf'. 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
Use the following command to send out the bundle with worksheet

aksh> analytics worksheets select name=cifsperf sendbundle

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