How get the KBps&tps data from the OnTap API

XIEBIN_GCABLE — Thu, 05 Jun 2025 06:16:04 GMT

We would like to get the KBps&tps data from the OnTap API, and we get the kindly feedback from you before.

But unfortunatly, the methods you mentioned before not work! We can't get the KBps & Tps DATA.

Would you please kindly tell us can we obain the KBps&Tps data from which package, inteface, attribute or etc...?

Or, from the api, there just no way to do this?

The KBps & Tps data are very very important to our current project, so we need your strongly and professional support.

The version of our ONTAP is NetApp Release 8.0.3 and the System Model is 7-Mode .

Now I can obtain the attributes and values of the disk from CounterData and CounterInfo in the com.netapp.nmsdk.ontap.api.perf package. Unfortunately, the description of the attributes are not clear enough, so we don't event konw how to find out the KBps and TPS.
Please help me to get the KBPS and TPS using those about the attribute?

For TPS, use total_tranfers for the disk object.

total_transfers: Total number of disk operations involving data transfer initiated per second

For KBps, sum user_write_blocks and user_read_blocks from the disk object.

user_write_blocks: Number of blocks t transferred for user write operations per second

user_read_blocks: Number of blocks transferred for user read operations per second

A block is 4 KB or 4096 bytes.
