Monitoring 

Various components, applications, and services are delivered with the Knowledge Management capabilities of SAP NetWeaver. Knowledge Management provides several monitoring and logging applications for these objects in the form of iViews. These applications check and monitor Knowledge Management in the background. They deliver information on the status and function of the various objects and contribute to the recognition of critical system events. Portal functions are used to carry out performance monitoring and activity tracing for Knowledge Management. You can use the information delivered by the monitoring, logging, and tracing applications to analyze the system and take appropriate action where necessary.

The monitoring and logging applications of Knowledge Management are integrated into the Monitoring workset of the portal. This workset is available to system administrators by default.

If all relevant prerequisites are met, you can monitor parts of Knowledge Management and TREX using SAP Solution Manager (see SAP NetWeaver 2004s Supportability Setup Guide on the SAP Service Marketplace at service.sap.com/instguides ® SAP NetWeaver ® Release 2004s ® Operations).

 

For more information, see Monitoring, Logging, and Tracing and Monitoring Technology and Logging.

 

Alert Monitoring with CCMS

Proactive, automatic monitoring is the basis for reliable operation of your SAP system environment. SAP provides you with the infrastructure and recommendations for the setup of alert monitoring. This allows you to recognize critical situations within Knowledge Management as quickly as possible.

The following monitors are available for monitoring Knowledge Management. You access them using transaction RZ20 in CCMS.

Monitor	Description
Components	These monitors are available in CCMS in the transaction RZ20. You can also display the monitors in the SAP Solution Manager using transaction solution_manager. For more information about these monitors, see Monitoring KM with SAP Solution Manager.

Trace and Log Files

Trace and log files are needed to analyze problems.

Knowledge Management uses the logging mechanisms of the J2EE Engine. System information is written to the file defaultTrace.trc.

Important Log and Trace Files

Content	File	Path
System information	defaultTrace.trc	.../usr/sap/<SAP_System ID>/JC<J2EE Engine Instance>/j2ee/cluster/server<n>/log/
Audit information on repository events	applications.log	.../usr/sap/<SAP_System ID>/JC<J2EE Engine Instance>/j2ee/cluster/server<n>/log/

 

For more information about monitoring trace and log files, see Monitoring and Displaying Log Files.

 

Operating System Monitors

No operating system monitors are included in the standard delivery.

However, you can set up a monitor in CCMS that displays the free memory space on the server used for managing the documents and folders of a file-system repository manager. The required data for this can be provided by the program SAPOSCOL.

For more information, see Operating System Monitor, Filesystems Monitor, and Editing Monitors and Monitor Sets.

 

Workload Monitors

No workload monitors are included in the standard delivery.

However, you can set up a monitor in CCMS that displays the workload of all nodes in a KM load-balancing environment. The required data for this can be provided by the program SAPOSCOL.

For more information, see Performance Overview Monitor and Editing Monitors and Monitor Sets.

 

Software Component Monitors

Monitors for technical components are needed to analyze problems.

The table below lists the monitors that are available in the portal to monitor Knowledge Management functions. To launch the monitors, choose System Administration ® Monitoring ® Knowledge Management in the portal.

Knowledge Management Monitors in the Portal

Monitor	Description
Component Monitor	Displays the status of objects and allows you to identify configurations with errors. The component monitor shows you an overview of all nodes of a load-balancing environment with their assigned scheduler tasks. Choose Services ® Scheduler in the component monitor. If a task is not assigned to a node, a red symbol is displayed. If this is the case, check the configuration of the corresponding task.
Cache Monitor	Displays statuses and statistics for active caches and allows you to empty caches manually.
Crawler Monitor	Displays information on the active crawlers and allows you to control them.
Indexing Monitor	Returns information on the status of current indexing processes.
Application Log	Displays error messages, warnings, and information generated by KM applications and services. Note that this information is not logged in the J2EE Engine log (see above).
