System Monitoring

What is the transaction code for the workload monitor?

/nst03

Using the Workload Monitor (aka Workload Analysis) tool, a report is given of CPU % which represents the percentage of time the CPU is involved in processing user requests. What four time sub-segments could be included to determine the total time the CPU spends processing a user's request?

1. Processing time 2. Memory roll-in 3. Memory roll-out 4. ABAP object load time

In the Database Monitor report, you see that the Database Buffer Quality is less than 60%. What should you do as an Administrator?

1. Stop the ECC system using the SAP Management Console. 2. Close and reopen the database using SAPDBA 3. restart the ECC system using the SAP Mgmt Console.

You run the Database Monitoring tool (/nst04 or /nst04n) and look at the reported value of Reads-to-User Calls. What value would you like to see?

>=25:1

In addition to Database Buffer Quality and Read:User Calls ratio, exclusive lock waits are also reported by the Database Monitor. Exclusive lock waits occur when a user begins to update a record in the database and gets distracted, thus "locking" that record from others working with it. As an Administrator, if you see the Database Monitor reporting a number of Exclusive Lock Waits occurring, what should you do?

Find the person holding the lock or manually delete the lock (try /nsm04) so others can work.

All monitoring statistics gathered from the tools mentioned this week and the CCMS must be considered at the same time without prejudice as to which tool was used to produce the statistics.

True

The CCMS Central Alert Monitor provides a range of monitors for monitoring the SAP environments and its components. These monitors are indispensable for understanding and evaluating the behavior of the SAP processing environment. (True/False) The CCMS should be monitored regularly and threshold limits adjusted _________ (True/False) The CCMS can be used in lieu of some of the other tools mentioned this week. ________

True/False

Quite often, an end user will raise an issue about a "lengthy response time". As you know, the response time is actually composed of many time sub-segments. What time sub-segment refers to the time a user's request is spent in the queue? ________ What time sub-segment represents the time a user's request is processed by the database? _________ What time sub-segment represents the time the ECC application system's CPU works on processing the user's request? _________

Wait Time/DB Response time/Processing time

In addition to time statistics, what is also important w/regard to the database?

The proportion of Database Calls to Database Requests

When reviewing the Workload Monitor report, you notice the CPU % idle time is extremely low, meaning the CPU is working hard to process user requests - and this situation seems to be the norm. What should you consider doing to rectify this problem?

Consider adding more memory (both RAM and virtual memory). Secondly, increase the buffer size parameter (zcsa/table_buffer_area) within the Instance Profile.

Bottlenecks can occur when memory buffer Swaps begin to occur. What should you do as an Administrator if you begin to see Swaps taking place?

Consider adding more memory (both RAM and virtual memory). Secondly, you can increase the buffer size parameter (zcsa/table_buffer_area) within the Instance Profile.

As an Administrator, you have a list of Daily tasks, Weekly tasks, and tasks which must be performed monthly with regard to Monitoring your system. In addition, when you receive a complaint from an end user, what tool should you first look at when investigating the user's concern?
