The difference between "RZ20" and "SM21"?

[Former Member]

Hi.

I want to observe the system log.

The system log has been described to "SM21" though I want to observe from "RZ20".

Question.

Is the watch of the system log possible by "RZ20"?

Hi,

TCODE :RZ20 is used for CCMS.

System Monitoring and Alert Management

Efficiently monitoring your entire IT landscape

Managing distributed mySAP.com solutions or client-server systems place high demands on the system administration - demands that increase significantly through the inclusion of the Internet in business processes. Using the Monitoring Architecture of the Computing Center Management System (CCMS), SAP provides a flexible and universally applicable infrastructure, with which you can monitor the entire IT landscape centrally and which quickly and reliable reports problems that occur.

The Monitoring Architecture is delivered with every SAP Web Application Server with no additional costs and can be used immediately after installation. The architecture runs on all SAP Web Application Servers and can easily be extended with SAP and non-SAP components.

Overview Using Alerts

Alerts are a central element of the monitoring. These quickly and reliably report problems - such as a value exceeding or falling below a particular threshold value, or an IT component being inactive for a defined period of time. To improve clarity, alerts are assigned certain colors - yellow for a warning and red for a problem - and a numerical value for the criticality of the problem. There are two products available to display the collected data:

Measured values and alerts are displayed in the Alert Monitor in various monitors, organized by topic. These monitors display the data in a tree structure in which the highest alert of a subtree is reported upward.

The SAP Solution Manager is focussed on the technical integration of applications, Software Change Management, and, above all, monitoring the most important business processes of the customer.

Analysis and Auto-Reaction Methods

You can assign analysis and auto-reaction methods to the alerts. These contribute to quicker processing of the problem. By double clicking on alert, you manually start the analysis method (for example, the job management transaction for a background job that has terminated prematurely). An auto-reaction method, on the other hand, starts automatically as soon as the alert occurs. These include the execution of operating system commands and sending an e-mail or an SMS message to the system administration.

Individually Configurable

Threshold values, methods, detailed help, and four extensive monitor sets with monitors for all aspects of system management are predefined in the monitoring architecture and are available in every SAP system. You can also customize all settings to your own requirements and, for example, configure customer-specific monitors so that only the data about your system landscape that is relevant to your needs is displayed.

Communication Using Agents

Remote monitored components are included using CCMS agents. These have the following properties:

Connection to the central monitoring system using RFC, to provide greater downtime security and universal usability

Use of a push mechanism to proactively report alerts and data to the central system

Integration of the SAPOSCOL operating system collector to transfer data for the operating system level (from CPU utilization and fill levels of file systems to details of individual monitored processes)

Connection of systems with SAP Basis 3.X and components on which no SAP Web Application Server is installed Monitoring of any log files
