My storage admin duties are growing and I need to understand performance and how to trouble shoot performance issues. I found tr-3525 but it is a little dated, and does not cover ops manager 4.0. I keep asking this question and people say it is an art and a science. Does anyone have any good resoruces for how to learn more on understanding and troublshooting performance?
I do have operations manager 4.0 and with NetApp Management console I get all the info I need, I just need to learn how to use.

Have you seen a specific course? I looked at university and I found
Operations Manager 3.7, Protection Manager 3.7 and Provisioning Manager 3.7 AdMinistration --- which is not for version 4 and also not being offered.
I also did the web based Getting Started with NetApp Software: Manage Efficient Storage Growth --- but it did not cover performance.

We have created a new TR-3836 (INTERNAL ONLY) on "Performance Diagnosis using Performance Advisor". This document provides best practices for using Performance Diagnosis feature available through Operations Manager 4.0. It is intended for Storage Administrators/NGS who want to troubleshoot the storage system for performance related issues.
Currently this TR is available from fieldportal (https://fieldportal.netapp.com/default.asp).

Would it be considered all right to pass along to sufficiently technical customers and/or customers under NDA?
I really like the ability in Performance Advisor now (given OM 4.0) to track aggregate disk busy-ness from a historical perspective.

Do you mean this TR can be shared with external customers ?
Answer is yes. But any modifications to the diagnosis configuration (including adding new rules) are recommended to be done under the guidance/supervision of NGS.

In the Performance Advisor section of NetApp Management Console 3.0 (come with Operations Manager 4.0), I specifically like to make a custom historical graph tacking aggregate:pa_avg_disk_busy, aggregate:pa_max_disk_busy, aggregate:pa_min_disk_busy.
I'm also experimenting with some alerts around aggregate:pa_mix_disk_busy if stays above 90% for more than 10 minutes (for example).
