Monitoring Transaction

Overview

The monitoring transaction, LTRO, is a tool which runs on the SAP Landscape Transformation Replication Server system and can help system administrators get a faster overview about the participating systems and configurations. For example, you can use the monitoring transaction to get information about:

  • The number of current running and free batch and dialog processes running on all application servers of the SAP LT Replication Server system.
  • The availability status for all connected SAP HANA target systems (for all selected configurations), and the corresponding log entries (warnings and errors).
  • The status of multiple configurations (mass transfer IDs) within a single screen.
  • The results of the SAP Landscape Transformation Replication Server health checks.

Even though you can use the SAP LT Replication Server Cockpit (transaction LTRC) to view the status of a single configuration, system administrators managing multiple configurations have to switch from configuration to configuration in order to see the relevant status. The benefit of using the monitoring transaction is to have all relevant information in one screen.

Overview Tab Page

The Overview tab page is divided into two sections. The left screen area contains SAP LT Replication Server system-specific information. The right screen area contains information about all connected SAP HANA systems (connected by means of the secondary database connection type ADBC).

In the left screen area, under Details, you can view the available application servers for the SAP LT Replication Server system. For each application server, you can view the number of free and available processes, and the maximum runtime (longest running process in seconds) for the processes (in seconds). The number of free process is an indicator for the load on the SAP LT Replication Server system. If a high maximum runtime value occurs, this could indicate an issue with a long running process.

At the top of the tab page, you can view aggregated values for the application servers. This is the total number of free and available processes, and the highest maximum runtime value (the longest running process across all application servers).

In the right screen area, you can view all the SAP HANA target systems that are connected to the SAP LT Replication Server system for all selected configurations. For each target system, you can view the target system status (a connection status), as well as the configurations assigned to the target system. Under Target Alerts, the system displays up to 20 database log entries for the last 12 hours. You can customize these settings in table IUUC_RM_PARAMS (field PARAM, value RCVR_ALERTS_INT for the time period, and value RCVR_ALERTS_NO for the maximum number of database log entries to be displayed). If the value under No. Target Alerts is "1-", this means that the system could not retrieve the database log entries. The reason for this is that the database user used for the secondary database connection is not authorized to retrieve this information.

Configuration View Tab Page

In the Configuration View tab page, you can view the status of the master job, and an overview of all configurations selected when the transaction was executed.

For each configuration, you can view information such as the name, status, technical ID, and so on. Note that some information is only visible if the configuration is active (for example the latency information and the status of the target system).

The benefit from this view is that administrators can see multiple configurations on a single screen without the need of switching from one configuration to another one.

You can navigate to the details of an individual configuration by clicking an entry in the Mass Transfer ID field or by choosing the Open Tables View pushbutton. To view additional information for the configuration, you can navigate to the SAP LT Replication Server Cockpit (transaction LTRC) and use the tab pages Table Overview, Data Transfer Monitor, and Application Logs.

Health Check Results Tab Page

On the Health Check Results tab, you can view the results of all the SAP Landscape Transformation Replication Server health checks. This can help system administrators identify the root cause of problems, and identify when the replication of a table encountered problems for the first time.

By default, the system only displays the results that have the status Error from all the health checks and for all the tables. If you would like to view the health check results that have a different status, choose Filter and change the time range for which the results are displayed. You can also filter the results bases on a specific table or check.
