Very cool! vscsiStats is a very useful tool, would be great to see this integrated into vCenter performance charts.

Generally script samples are posted under VMware Sample Code ... though there not a section for python. Nonetheless, very nice script!

Hi Jeremy,

The script is great!

-Spark

Great script - I wrote some similar scripts to help centralize and quantify the IO load per VM on my NFS datastores to prioritize VM realignments.

I just filed a feature request SR 1471853531"Please bring the vscsistats (/usr/lib/vmware/bin/vscsiStats) into VC and align with existing APIs.

Currently the command offers a wealth of stats but only on the command line and only  per ESX host.

Centralizing them into VC would provide:

1) IO stats per VM on NFS datastores (unavailable via esxtop)

2) Provide standard Trending, Alerting etc

3) Help answer questions like which VMs need to be storage vMotioned to less loaded datastores

thanks"

VCP

can you please explain how to run this script on ESX4?

I uploaded it into datastore, and did chmod 700 nfstop, but when I run ./nfstop it says: Please install the /sbin/vscsiStats binary.

The versions posted above do not run in ESX 3.5 due to the version of Python (Py 2.2 in ESX 3.5, Py 2.4 in ESX 4.0 and Py 2.5 in ESXi 4.0).  We made a couple changes here at NetApp and got it to work, but when I wanted to post it back I was informed that we have certain legal procedures to follow when we modify somebody else's code and wish to re-publish.  We're now working through that so I can share it.  The changes are minor and anybody reasonably proficient in Python could figure it out, so have at it, or stay tuned.
