NexentaStor Project - Statistics collection - NexentaStor Project

Hi, I would like to collect some statistics per Folder,protocol,volume polling each few seconds. Stats I'm interested in are: (CIFS/NFS) avg_latency per Volumes/Folder (CIFS/NFS) read_latency per Volumes/Folder (CIFS/NFS) write_latency per Volumes/Folder (CIFS/NFS) read_ops/s per Volumes/Folder (CIFS/NFS) write_ops/s per Volumes/Folder (CIFS/NFS) read_data/s per Volumes/Folder (CIFS/NFS) write_data/s per Volumes/Folder cpu_util%

In a NetApp Filer I can achieve that my running 'stats show volume'

What Can I use in Nexenta/OpenSolaris to get this data?

Thanks.

We can't currently get those statistics from within the appliance and we have a request for that to be added to the product.

We understand that this is a gap and one of our senior engineers wrote some dtrace scripts where this data could be collected from the command line as root to bridge the gap.

You can find those scripts here

Actually, getting those stats from command line is preferred. These scripts are almost what I needed, so thank you so much. Only problem is that the results are per client and not per Volume. Any idea how I do that per volume or even better, per folder?

Thanks.
