You will be happy to know that in this  article, I will help you to gain knowledge of what is the architecture of monitoring in an SAP system. Reading the article carefully to make yourself clear about different terms that are used to build the CCMS alert monitoring infrastructure in an SAP system could become very advantageous for you to enhance your knowledge just like my satisfied students from over 55 countries who attend my high impact sap bias training course.

To process different business functions in an sap system, there are many components are involved within the sap system. you must have to monitor these components at regular intervals to prevent errors in advance in an SAP system. This type of monitoring avoids deterioration of performance or a sudden breakdown of an SAP system.

You have to use the CCMS Alert Monitoring Infrastructure to make your job of monitoring simple for monitoring entire SAP system efficiently and centrally.

You must read the following definitions repeatedly for 5-10 times which will make you very clear for using the terms appropriately while answering sap basis interview questions.

Monitoring segment:

The part of the main memory which has monitoring data, that is collected by CCMS alert monitoring infrastructure. Each component of an SAP system collects its own monitoring data by CCMS alert monitoring infrastructure and stores the collected data in the main memory.

The SAP system which is assigned for central monitoring of data that is collected by CCMS alert monitoring infrastructure, should have, as high a release level as possible and its availability should be as high as possible.

The central monitoring system collects the monitoring data for the components and displays it in various views. In this way, you have a central view of each component of the entire SAP system landscape.

The CCMS Alert Monitoring Infrastructure consists of three parts. These parts of CCMS alert monitoring infrastructure are data collection, data storage, and its administration.
Now let’s look each one of them in detail. Now that’s agin one of the biggest and huge advantages of my quality sap bias training videos, here you will find every thing in detail.

Data collectors

Data collectors are the special programs (ABAP, JAVA or C), that are used to check each sub component of an SAP system and stores the data in the main memory of its host.

Data storage

The area of this main memory is called the monitoring segment. Because the data in main memory is always overwritten, it can be permanently copied to database tables. This data helps you to analyze the problem area in an SAP system. Every instance of an SAP system has its own monitoring segment in its shared memory.

Data administration

The data from the monitoring segment will allow you to display and evaluate it. You can use expert tool CCMS alert monitor (RZ20) to analyse the problem to get a solution.

CCMS Alert Monitor, transaction RZ20

You have to use RZ20 t-code either in an SAP Netweaver system or in an SAP Solution Manager system to display the collected monitoring data from the monitoring segment of an SAP instance. If the system identifies a problem, it can execute an auto reaction, such as informing the person who is responsible. The analysis method then helps you to investigate the problem further to get an idea to solve the problem.

Monitoring Tree Element (MTE)

Monitoring Tree Element (MTE) is a node in the tree structure within CCMS Alert Monitor (RZ20). The clear display of large number of measured values are possible with the help of tree structure.

Monitoring Objects

Monitoring attributes are bundled together and forms as monitoring objects at the second-lowest level within the tree structure of CCMS alert monitoring infrastructure. For example, the monitoring object program buffer contains, among others, the monitoring attributes hit rate and swap.

Monitoring Attributes

The measured values that are collected by the data collectors are displayed at the lowest level in the leaves of the tree. These leaves are called monitoring attributes.

Threshold values

Threshold values can be stored for a monitoring attribute. SAP delivers default threshold values. However, you can also adjust these threshold values if required using the concept of properties variants in the CCMS alert monitoring infrastructure.

Monitor set

You can display the different preconfigured monitor sets by using t-code RZ20. You can also create your own monitor sets by activating maintenance function in the same initial screen of CCMS alert monitor (RZ20)


Monitor is a part of the entire CCMS alert monitoring infrastructure which is used to display the values of different monitoring attributes. You can create your own monitors within the monitor set that you have created.

How to start the CCMS Alert Monitor (RZ20)

The CCMS Alert Monitor is started by calling either transaction RZ20.


Using the SAP Easy Access menu, choose Tools → CCMS → Control/Monitoring → Alert Monitor. The following image shows you different functions of computing center management system.

The two views available in an SAP system for monitoring an entire SAP system are as follows…

The Current Status view: This view displays the monitor with the newest reported data.
The Open Alerts view: This view displays the monitor with alerts that have not yet been completed.

You can also extend the CCMS Alert Monitoring Infrastructure. Third-party vendors and partners can export the monitoring data from the monitoring segment using various interfaces and then use the data for different type of problem analysis.
