Telegraf NFS Plugin

Hi I can see with Telegraf 1.18 NFS plugin is now included.

I am interested to have the capability to use the fullstats to look at READDIR plus latency.

[[inputs.nfsclient]]

fullstat = true
include_operations = ["READ","WRITE","ACCESS","GETATTR","READDIR","READDIRPLUS"]

I am using the following plugin configuration however when I look at the operations I still only have READ and WRITE and nothing else.

Is there any advice on how to get the additional operations data to show?

Thanks
