SAP Netweaver - Overview of 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 contains tools for administering and archiving the alerts.

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.
