Technical System Landscape

Use

The alerts are displayed in a tree structure in the alert monitor, and assigned a severity and a color (yellow for a warning, red for a problem). You can see the current status of your system and process alerts here. The alert monitor is based on the monitoring architecture:

You can display monitoring data for the following components in the central monitoring system (CEN):

Systems based on SAP Web AS ABAP and Java
SAP systems with earlier releases (as of SAP R/3 3.0)
Non-SAP components

The data is transferred to CEN using CCMS agents or ABAP RFC connections. You can display it there directly in the Alert Monitor, or forward the data to external tools or SAP Business Intelligence for additional evaluation.

The elements of the monitoring architecture function largely independently of each other and can, particularly, be further developed and adjusted independently of each other.

The alert monitor also provides the administration methods that you need to monitor the system. These enable you to set threshold values for alerts and add or adapt auto-reaction and analysis methods. Auto-reaction methods react automatically when an alert is triggered; analysis methods enable you to examine the cause of an alert without leaving the alert monitor. The monitoring architecture also has tools for managing and archiving alerts. The monitoring of your system landscape also works with the following programs:

Program/Application	Description
CCMS agents	CCMS agents are independent processes that connect a monitored component (such as a host, an ABAP instance, or a Java instance) with CEN using RFC.
Operating System Collector SAPOSCOL	SAPOSCOL is a stand-alone program that runs in the operating system background. It runs independently of SAP instances exactly once per monitored host and collects data about operating system resources.
Availability Monitoring with CCMSPING	With this type of monitoring at system or instance level, the CCMSPING agent queries the relevant message server about which instances are reported as active. You can also have the instance availability of ABAP systems monitored using a direct RFC call to the instance itself.
Monitoring with the Generic Request and Message Generator	With this type of monitoring at application level, CEN periodically calls a GRMG application using a URL. The GRMG application performs component-specific checks and returns the result of the checks to CEN.

Note

For information about the high availability of the monitoring infrastructure, in addition to the general documentation about SAP High Availability, see SAP Note 536954. It describes the settings required for the failover of CCMS agents in high availability solutions.
