ADM100 Lesson: Monitoring Architecture
Each component collects its own monitoring data using the infrastructure
and stores it locally in the main memory. This part of the main memory
is called the monitoring segment. You can configure the size of the
monitoring segment.

have as high a release status as possible (at least SAP R/3 4.6C) and a high
level of availability. In large system landscapes, we recommend that you
include a separate system that is used only special tasks such as central
monitoring, Central User Administration, transport domains controller,
or the SAP Solution Manager. From a performance point of view, the
workload of the central monitoring system increases only insignificantly,
as the collection of monitoring data is usually decentralized.
The central monitoring system collects the monitoring data for the
components and displays it in various views. In this way, the administrator
has a central view of the entire system landscape. If errors occur, the
administrator can jump directly from the central monitoring system to the
appropriate component to correct a problem in a detailed analysis.
Details
The monitoring segment (in shared memory) is provided with a large
q uantity of data about the system by different types of data collectors
(active/passive). You can use either transaction RZ20 or the SAP Solution
Manager to read and display the data. SAP also provides interfaces that
allow external tools (such as HP Open View) to access this data.
Definition of active/passive: An active data collector automatically collects
data without an external trigger, for example the dispatcher. A passive
data collector collects data due to a trigger, for example through the report
SAPMSSY8, which runs every five minutes.
The CCMS Alert Monitoring Infrastructure consists of three parts: Data
collection, data storage, and administration.
