The Alert Monitors SAP BASIS

The Alert Monitors are a set of monitoring tools for alerts in the system that comprise a great variety of areas to check for performance, stability, and errors across your SAP R/3 system and other systems as well. These are also often called simply "CCMS monitors" and they are part of the Computer Center Management System utilities, under which are the jobs, spool and database administration and monitoring tools, as well as the configuration tools that you have learned to use in previous sections.

Architecture of the Alert Monitors

These Alert Monitors were introduced with a new architecture in release 4.0 and have grown exponentially in functionality and availability to be used as central monitoring tools for a SAP system. In fart, the monitoring capabilities of Solution Manager are based in the CCMS Alert Monitors. In order to understand how the alert monitors are built, let us define the elements that comprise the tools and how they are related.

  • Data suppliers. Data suppliers are programs that collect information from different parts or components of the SAP systems, such as the operating system, the database, and so on. They keep information related to different Monitoring objects. The data collected are transferred to different Monitoring Objects visible from SAP.
  • Monitoring objects. These objects represent different elements or system components that can be monitored within SAP and its environment. Monitoring objects are created by data suppliers, which are also in charge of collecting information about the monitoring objects. Each type of information that can be collected for a monitoring object is known as an attribute. For example, a monitoring object can be swap space and its attribute space used, with a value of 10 percent, which is the data collected by the data supplier. Monitoring objects are like branches in a tree, the monitoring tree elements. Another way of understanding monitoring objects is to consider them as instances of a particular monitoring template. This instance is fed with data provided by the data suppliers.
  • Data consumers. These are programs that, depending on the monitoring object status, process the object information collected from data suppliers. This information is used for management, monitoring, and analysis. Like the data suppliers, the data consumer programs are linked to monitoring objects using BAPIs, so they can be cither SAP or external programs.
    Based on the information provided by the data supplier, you can work with the alert monitors to
  • Trigger alerts in case of errors or warning, displaying them in different colors, Red, Yellow, or Green, depending on the severity. This can be defined by the delivered thresholds or you can customize them.
  • Manage and display detailed information about the monitoring object, as well as permitting changes in its configuration, such as the definition of alert thresholds. Assign on-alert tools to the monitoring objects, so that automatic reaction to alerts can be configured.
  • Assign analysis tools to the monitoring object for the analysis and determination of the causes for alerts.

You must assign the so-called methods to the configured monitoring attributes. A method can be a program, a function module, a SAP transaction, or a URL to be executed as a reaction to an alert. You can execute these methods within the Alert Monitor. If you double-click, for example, the monitoring tree element (MTE) for buffer swaps, you will be taken to the Buffers Monitor (transaction ST02), where you can start your analysis to correct the situation that triggered the alert. There are standard delivered methods that allow you to monitor the system. You can change the method assignments, if you wish for another one or a custom method. Also, you can transport method definitions to other SAP systems. Methods are different and have different properties. To define and assign methods, execute transaction RZ21.

There are Data Collection Methods, which basically accrue information and send it to the monitors at specified times. Also, there are Auto-Reaction Methods, which are launched automatically when an alert is triggered. With these methods, you can send e-mails to the system administrator or who you define as responsible for a certain area, call an operating system command or script. The Analysis Method leads you to detailed analysis of error situations from the Alert Monitor.

The Alert Monitors

Execute transaction RZ20 or follow the menu path Tools| CCMS | Control/Monitoring | Alert Monitor. You can choose between a list of monitor sets. The SAP CCMS Monitor Templates and the SAP CCMS Technical Expert Monitors contain the featured monitors in previous releases and more new utilities. The SAP Business Communication set is used to monitor SAPPhone and SAPConnect, and the SAP CCMS Monitors for Optional Components can be used to monitor external systems or other components, such as a print server.

In order to check alerts in the system where you are logged on, expand the CCMS Technical Expert Monitors and double-click on the line named System/All Monitoring Segments/All Monitoring Contexts. The trees that you display will be colored according to the severity of the alert and you must go down the branches until the original root cause of the problem. See Figure. There you can start an analysis method, if it has been defined that way, or just display some statistics, if that is the method that you assigned.

The view by default is the Current Status view, which gives you the actual status of the system. The Open Alerts view that you can choose by clicking on the pushbutton with that name gives you an overview of all the alerts recorded that happened at some point in time. Alerts will remain there until you "complete" them. To complete an alert, you must select it and choose Complete Alerts. There is a way to complete alerts automatically, but you must play with one of the methods and set its parameters accordingly. It is efficient to use the method CCMS_Segment_Spacc_Collect and change the parameter CMPL_ALERT_AFTER_DAY (number of days to keep the alert).
