Keep in mind that you cannot legally access AWR reports (or AWR/ADDM data) unless you have the Enterprise Edition of Oracle AND a Diagnostic Pack License. If you do have a Diagnostic Pack License, you should be able to just use the Performance tab in Enterprise Manager Database Control and review ADDM reports.

I am looking for a Performance tools which can give me the Charts of all my Database & OS performance . I have tried using OS Watcher but i am looking for a tool which has both Database & OS Performance integrated .

My company cannot afford money to buy a tool this is the major constraint.

Any recommendations which comes to your mind will be appreciated , either it can be a ready maded tool or technical tips to gather stats or AWR reports to excel and develop charts or what ever you recommend .

Here is code to have Excel automatically execute a Public Sub (macro) in a module after 60 seconds:

Application.OnTime DateAdd("s", 60, Now), "CollectStatistics"

If the above is placed in the CollectStatistics Sub, that Sub will automatically re-execute every 60 seconds once the user manually executes the Sub for the first time.

(Retrieve Data to Excel with a Macro using ADO ) Are you talking about this one ?

The use of the program in the examples of the blog articles is intended to inspire people to think outside the box, so to speak, and allow *you* to put together your own solution for detecting performance problems. Note that there are articles on this blog that show how to bring Oracle data into Excel – it is then possible to create an auto-scrolling chart in Excel that would then, for instance, show a running history of the last 60 minutes for a specific statistic. In a later blog article I may show how to create such an auto-scrolling chart.

Late follow-up:
This particular performance problem highlighted a couple of weaknesses in my program, which were correctly quickly after this performance problem was identified. The program’s capture periods are variable in length, with those captures being triggered either when an elapsed time timer expires or an event happens in the database (such as unexpected, excessive CPU consumption). At the time of the capture, the program did not line-level the statistics shown in the graph to an average rate per minute, which very likely means that the first tall green bar does not represent a problem.

A second weakness appears in the SQL Monitor that was originally designed to work with Oracle 8i databases. Prior to Oracle 9i R2, Oracle did not provide a CPU_TIME or ELAPSED_TIME statistic in V$SQL. Since this portion of my program was not significantly updated since originally developed, those two key statistics that could have been used to directly tie one or two SQL statements back to the spike in overall CPU usage were not readily available without manually sampling V$SQL (or one of the other views).

I guess you are using some software tool to analyze the performance . What is that ?
