Exporting AWR data in a csv file [message #671401]

Hi,
I would like to export specific data from AWR report onto a csv file. For example, I would like to export top 5 wait events for a specific snapshot from AWR report onto a csv file. I will then use this file to plot a graph for better understanding.
Are there any sql scripts that I can use, or if you can point me in the right direction where I can develop the scripts.
Thanks

What is on the X-axis?
What is on the Y-axis?
So what exactly will you better understand?

X-axis will be the time period. Y-axis will be any event from AWR. For example, i would like to plot the wait event "buffer busy waits" for a period of 30 days. Or plotting how a particular sql_id fared interms of elapsed time over a period of 10 days.

But what if performance issue was NOT not due to wait event, but resource depletion of CPU, RAM, or I/O?
How do you know or decide why things were slow definitively?

I am using the term performance only as an example. Basically, I require a script to plot various events ( CPU, IO, memory, waits, etc) against a give time period.

GOOGLE is your friend, but only when you actually use it.

Is this not standard functionality in Cloud Control? CC is free, you might as well use it.

More or less, doesn't always give quite the precision I like though.

@OP: Just dump the data out into a sql*plus spool session. DBA_HIST_* views are what you want.
