Measuring performance

[Former Member]

Hello Experts:

I am separated by 12 hrs from where the SAP instances are located and support are available. Also, I am not an infrastructure expert but required to go into SAP transactions and record screen shots of system performance at a given point in time and find the root cause of poor performance (like saving sales order taking 5 minutes!). With this proof, will have to present my case and look for support whenever available.

Any guidance / documentation would be much appreciated.

Thanks,

HI UV

workload Monitor (ST03N ) is the best transaction to check for performance issues.

However, there are certain methods to look for things in there depending on the details available with you.

Firstly if you are monitoring the data in runtime, you will have to check data for a specific instance. For problems occuring in past days, a TOTAL data can be viewed which would give data combined for all the application servers.

Next , depending on the details available with you ,i.e. specific transactions or user etc. who are facing performance problem, a selection between transaction profile or user profile can be made.

Then further, the response times can be checked. You need to check what constitutes maximum in the average response time. For e.g. a high DB time suggests that the query is taking long at the DB level.etc.

Apart from this, real time performance problem can also be detected by transaction STAD. This would also give you ample data to be indicative on the exact issue.

I hope this helps you

Hai,

You can use ST03N to gather data for all the Transactions executed in the SAP system.

ST03N also gives you the amount of time, memory, etc., to analyze the performance of the system.

Hello Yoganand,

Thanks for the docs. It was helpful.

Should I be looking into specific fields to look for patterns that would take me in the right direction?

Thanks
