Question: How do I read a STATSPACK report?

Answer: Reading a STATSPACK report can be very tricky.

The STATSPACK report is an offshoot of the old bstat-estat report, which was create for Oracle internal-use only and it is not documented by Oracle. Many of the performance metrics are undocumented also and required detailed knowledge of Oracle internals, and reading a STATSPACK report requires considerable knowledge.

Understanding all of the sections of a STATSPACK report is quite complicated, and I have a whole chapter dedicated to reading a STATSPACK report (and the AWR report) in my new book "Oracle Tuning: The Definitive Reference".

Also, you can paste-in a STATSPACK report into http://www.statspackanalyzer.com and learn how to analyze a STATSPACK report. There are several Oracle Press books on STATSPACK, you may find useful for learning to read a STATSPACK report..

In a nutshell, the most important areas to read in any STATSPACK report are the top-5 timed events and the statistics for the major database events. The I/O statistics are also very useful. I have my notes on how to read a STATSPACK report here:
