If you have some Nagios-compatible Systemmonitoring in place (op5, Icinga, Shinken, ...) you can try the monitoring-plugins from https://netapp-monitoring.info/en/. They allow a quiete detailed view and analysis.
Hi smbsmbsmb, today you can integrate OnCommand System Manager w/ OnCommand Performance Manager, and the direction is the fully convergence between both tools in only and simple one. Those tools are included on ONTAP Systems with no charge and will provide the graphical UI for performance and capacity planning, showing how much room you already used from your systems, helping on solve performance problems and telling if you can add new workloads or need more spindles or compute. You'll have access to a ton of resources linke reports and alerts. This is the way to go if you want to simplify your day-by-day management.
The OATS have a cost related with AWS. NetApp doesn't charge for license, but as a SaaS you will be charged for the CPU, Memory and capacity used from AWS and it is a tool much more related to help the customers on solving performance problems only. It will have a Analytics in near future to help find out what's going on and how to solve complex storage problems.
Expect that helps! Please get back to us to tell about you experience with this tools!
We've been an OnCommand Unified Manager + Performance Manager (7.1) shop since we rolled ONTAP 9. Now that the two tools are integrated into 7.2 I'm a huge fan. The old tool was a little clunky when you'd switch between a health and performance view but since they're all in one right now it's very easy to use.
I listened to the OATS TechONTAP podcast and it seems like that would be a great tool for sleuthing out bigger performance issues (like gathering a perfstat used to provide) but for a lot of what we need in our day-to-day operations, OCUM 7.2 fits the bill - and is free...
