Measures reported by NAUSDSysPerfTest

Using this test, the overall performance of the NetAapp Unified Storage system can be measured with key measures such as the following:

  • The average latency for all the operations performed on the system;
  • The disk throughput of the system;
  • The network throughput of the system and
  • The rate at which read and write operations were performed on the system.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Sys_avg_latency Indicates the time taken for performing all the operations in the NetApp Unified Storage system. Milliseconds A low value is desired for this measure. The responsiveness of the NetApp Unified storage system can be measured with this measure.

The Detailed diagnosis of this measure indicates the exact cause for the sudden slowdown in responsiveness of the system.
Disk_data_read Indicates the rate at which data is read from all the disks of the NetApp Unified Storage system. KB/sec A high value is desired for this measure.
Disk_data_written Indicates the rate at which data is written to all the disks of the NetApp Unified Storage system. KB/sec An abnormally high value indicates that the disk is taking too long to store the data which may be due to the disk being full or a processing bottleneck or a network slowdown.
Data_received Indicates the rate at which data is received through the network to the NetApp Unified Storage system. KB/sec A high value is desired for this measure. A low value indicates a processing bottleneck or a network slowdown.
Data_sent Indicates the rate at which data is sent through the network to the NetApp Unified Storage system. KB/sec  
Http_operation Indicates the rate at which HTTP operations were performed on the NetApp Unified Storage system. Ops/sec HTTP operations include management operations. Usually log processing is done using the management web interface of the NetApp Unified Storage system. The value of this measure will increase if there is excessive log processing activity in the management web interface.
Read_operation Indicates the rate at which read operations were performed on the NetApp Unified Storage system. Ops/sec  
Write_operation Indicates the rate at which write operations were performed to the NetApp Unified Storage system. Ops/sec  
Raid_read_latency Indicates the average time taken for all read operations from WAFL to the RAID of the NetApp Unified Storage system. Milliseconds Ideally, the value of this measure should be very low.
