We'd like to programatically poll our filers (from java) at 1-5 minute intervals for the following data points:
Latency Disk capacity used (per volume) Disk capacity growth rate (per volume) Disk throughput (reads/writes) (per volume) NFS Ops/second CPU % Network throughput
I've been looking through the Netapp Manageability SDK, which has libraries for ONTAP and DFM, but I'm unclear if either of these is what I need to get the data I'm looking for, and if so, what the field names I'm looking for are. Ideally, we'd like to directly query the filers rather than going to the DFM servers, since we have multiple DFM servers and don't want to have to track/manage which servers are querying which filers.
If anyone could point me in the right direction (what library to use, where I can look up the fields I'm looking for) that'd be greatly appreciated.
