I am trying to create a custom group with nas_stats:

nas_version 6.0.36-4

I have a list of all the sets I am interested in (NFS2/3/4 and SMB/2) .calls only. Now I want to combine them into a custom group.

Lets start with the fact that man page contains an error:

EXAMPLE #6

To use an existing statgroup, type:

$ nas_stats -groups -create statgroup1 -description "My first group"

sys.cpuUtil,net.basic.inBytes,net.basic.outBytes,store.readBytes,store.writeBytes

ERROR (13421969439): 'statgroup1' already exists.

Thats a poor example...

And continue with the fact that it appears you cannot add specific counters into custom group:

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" kernel.cpu.utilization.cpuUtil,kernel.memory.freeBytes

ERROR (13421969427): Invalid statpath name: kernel.cpu.utilization.cpuUtil

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" kernel.cpu.utilization

ERROR (13421969427): Invalid statpath name: kernel.cpu.utilization

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" kernel.cpu

ERROR (13421969427): Invalid statpath name: kernel.cpu

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" kernel

ERROR (13421969427): Invalid statpath name: kernel

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" kernel-std

ERROR (13421969427): Invalid statpath name: kernel-std

The only thing you can add, is a pre-defined system group:

[nasadmin@krasnodar ~]$ nas_stats -groups -create basic3 -description "CPU and Memory" basic-std

'basic3' created successfully

Is this FAD or a very broken feature?
