Monitoring Parameters, Availability, Log Files, and Processes 

Use

You can use the monitoring functions of CCMS (Computing Center Management System) to monitor Search and Classification (TREX).

There are the following areas for monitoring TREX with CCMS:

●      Parameter and version reporting

●      Availability monitoring (Heartbeat/GRMG)

●      Log file monitoring

●      Process monitoring

Prerequisites

You have configured CCMS monitoring for TREX so that parameters, availability (heartbeat/GRMG), log files, and processes can be monitored in CCMS.  

●      Configuring Parameter Reporting  

●      Configuring Monitoring of Availability (Heartbeat/GRMG)  

●      Configuring Monitoring of Log Files  

●      Configuring Monitoring of Processes  

Features

●      Parameter and version reporting

You can use reporting for important TREX configuration parameters in a CCMS system. This includes the paths for indexes and the TREX version. Information such as the trace level and queue and index information (such as the size of the hard disk and languages) is available.

●      Availability monitoring (Heartbeat/GRMG)

The availability of TREX services can be checked using a heartbeat with GRMG. A scenario in CCMS describes a single TREX host. If you want to monitor a distributed installation with multiple TREX hosts, each host has its own scenario in CCMS. The system can check the availability of the TREX index server, queue server, preprocessor, name server, and Web server.

You can run more than one TREX instance on a TREX host. For each TREX instance, you can use a TREX GRMG server that monitors the availability of the TREX server for this TREX instance.

●      Log file monitoring

You can monitor trace and log files using a template. If an error occurs in a log file an alert is displayed in the CCMS system.

●      Process monitoring

You can monitor TREX processes that are currently active. This implementation is similar to availability monitoring, where a scenario on a server is checked in various steps.

 

Activities

For all CCMS monitoring features, you use transaction RZ20:

...

       1.      Start transaction RZ20.

The screen containing the CCMS Monitor Sets appears.

       2.      Expand the SAP CCMS Monitors for Optional Components node.

       3.      Double-click the TREX entry.

A node tree containing the following entries appears:

○       TREX Server Heartbeat (all Releases)

○       TREX (Release <= 6.40)

○       TREX (Release >= 7.0)

       4.      Choose a TREX release.

This is the default path for TREX scenarios. If you have defined your own monitors, follow the relevant path in your system.

○       Parameter and version reporting

Information about the Operating System, Host Name, CPU, and so on for your TREX system appears.

○       Log file monitoring

                                                  i.       Navigate to the TREX Log Files node and expand it.

A list of the available TREX trace files appears.

                                                ii.       Choose Open Alerts.

The open alerts are displayed. Choose an entry for an open alert to display detailed information.

○       Process monitoring

Choose the TREX Process Monitoring entry.

A list of entries for various TREX processes that are monitored by the CCMS monitor appears.

The TREX admin tool (stand-alone) also provides a monitoring function for monitoring processes, errors, and alerts. The TREX alert server regularly checks central TREX functions and can notify you by e-mail of the system status in the event of an error or incorrect configuration.
