Matt –

To review, there are several options:

1. Use SNMP.  Scan the file netapp.mib and look for “Ops”.  You should find various protocols returning IOPs.

2. Parse sysstat output.

3. Use the APIs.  There are 2 types of APIs: ONTAP and OnCommand (Operations Manger, DFM).  The ONTAP APIs will only give you information about a specific storage controller.  The OnCommand APIs can give you information about multiple storage controllers that the OnCommand server is managing.  One person already gave you a communities pointer to the APIs.  Here is a pointer to using Performance Management APIs: http://communities.netapp.com/docs/DOC-1044.

You should also check-out the NetApp communities.  It contains a lot of information.

Regards,

Hi all,

Does anyone know if there is a way to calculate the number of IOPS a filer is handling via SNMP or some way to script a collection ?

Thanks

Matt
