I already generated EWA report and I got the following result:

 

1. Performance Overview PRD

 

 

The performance of your system was analyzed with respect to average response times and total workload. We have detected some problems that may impair system performance.

 

To ensure adequate performance in your core business transactions, you should take corrective action as soon as possible. For further information, please SAP Support.

 

Rating     Check

     Performance Evaluation

 

The following table shows the average response times for various task types:

 

Task type     Dialog Steps     Avg. Resp. Time in ms     Avg. CPU Time in ms     Avg. Wait Time in ms     Avg. Load Time in ms     Avg. DB Time in ms     Avg. GUI Time in ms

DIALOG     212990     1595.2     257.7     31.0     5.0     622.2     136.8

SPOOL     9989     1686.8     37.1     55.6     0.3     49.2     0.0

 

1.1. Current Workload

The following table lists the number of current users (measured from our workload analysis) in your system.

 

Users     Low Activity     Medium Activity     High Activity     Total Users

Measured in System     162     119     6     287

 

1.2. Performance Evaluation

 

The measured times are compared against reference times to provide a rating.

- If the number of dialog steps in an hour is less than 1000 this hour is not considered.

- If the total number of transaction steps is less than 24000, the rating for the task is not performed and a blue line is entered in the table.

The table below shows that a performance problem is expected for the task that is rated YELLOW.

The ratings in the table above are determined by comparisons against the reference table below.

If the dialog response times are very poor, it will cause a RED rating for the entire check.

 

 

Task     Reference for Avg. Response Time (ms)     Reference for Avg. DB time (ms)

Dia     1200     600

Upd     2400     1200

HTTP     1200     600

 

1.3. Transaction Profile Check

 

The following tables show the response times and the number of dialog steps for the transactions that cause the highest workload in your system. NOTE: A business transaction normally consists of more than one dialog step. As a rough estimate, the actual number of business transactions that are executed in your system is approximately one third of the total dialog steps shown. (Transaction CPIC/RFC is not taken into account.)

1.3.1. Transactions by Total Workload

 

The following tables list the activities with the highest contribution to the total workload.

 

WORKLOAD BY TRANSACTION (DIALOG/UPDATE)

0.6% of the "Total Resp. Time" in the above table is caused by customer transactions.

 

According to our analysis, the main system load is caused by background jobs.

The EarlyWatch Alert Service can only detect performance problems for dialog, update and RFC response times. This service does not evaluate performance problems for background jobs.

1.3.2. Transactions by DB Load

 

The following transaction profiles list the transactions that have the greatest share in the database load, sorted by percentage of total database access times.
