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?
