cDOT performance API issues

I got some quries from customer about the cDOT performance monitor. So look for some help!

Here is a list of open topics:

What is the format of preset file? Is it the same as 7-mode?
Is “statistics preset import” the only way to import new preset file? In 7-mode, I can directly write the a preset file to the root file system.
- By using “statistics preset import”, I need to establish an HTTP/FTP server somewhere at first.
- Does it support HTTPS? Otherwise filers in DMZ will not able to get the preset file.
Please suggest where I can find the following 7-mode counters in cDOT:(is there any docs list all the cDOT counters? or how can I easily find mapping counters between 7 and C?)
- cifs_stats
  - offload_qlength
- ifnet(physical port)
  - recv_packets
  - send_packets
  - recv_data
  - send_data
- For NFSv4/NFSv4.1 stats:
  - Do nfsv4 counters tick with nfsv4.1 traffic?
  - Are “read_total” and “write_total” talking about IOPS?
- There’s no way to specify preset file in API.
