The latter I'm clear on, but can anyone help me differentiate between the "op/s" fields and the "ops/s" fields included in the read and write figures? I would have assumed the field in question is a total of the read and write figures for that mount point, but the math doesn't always add up.

Looks like you have to update to testing, or use pinning. Or just compile it yourself.

Does anyone know if there is in fact a packaged version of it, or what happened to it? Thanks, looks like a great article, I'm certainly looking forward to more. I've been interested in improving performance of my NFS servers for a very long time!

I am curious about the numbers reported, because they seem pretty high (up to 19616400 wkB_svr/s i.e. 19 GB/s). What type of NFS server was used? It would be also interesting to know your opinion about the output of nfsiostat: wkB_svr/s is related to wBlk_nor/s and wkB_svr/s continues for a while after wBlk_nor/s has gone down to zero. Is it due to client buffers? Good article to continue with the storage monitoring series.
