Dimensional Semantic Layer Bridge Service Test

The semantic layer allows SAP BusinessObjects Web Intelligence to deliver documents, by utilizing multiple synchronized data providers, including online analytical processing (OLAP) and common warehousing metamodel (CWM) data sources. Tracking the connections and requests to the semantic layer will help administrators assess how efficiently the semantic layer handles the requests it receives and identify bottlenecks (if any). To monitor the load on the semantic layer and measure its load-processing ability, administrators can use the Dimensional Semantic Layer Bridge Service test. This test keeps an eye on the requests received by and connections to the semantic layer and reports the count of data requests still to be serviced by the layer, thus pointing to probable processing bottlenecks.

Target of the test : A SAP BOBI Node

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the Adaptive Processing Server in the node monitored.

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed.
Host	Host name of the server for which the test is to be configured.
Port	Enter the port to which the specified host listens. This should be the port at which the web application server hosting SAP BOBI listens.
JMX Remote Port	Specify the RMI port number of the BOBI monitoring application.To know the RMI port number of the monitoring application, refer to Enabling the Monitoring Application of the SAP BOBI Platform.
JNDI Name	Specify the lookup name for connecting to the JMX connector of the BOBI monitoring application. To know the JNDI name, refer to Enabling the Monitoring Application of the SAP BOBI Platform.
JMX User and JMX Password	Enter the credentials of an enterprise authenticated BOBI user belonging to the default monitoring users group.
Confirm Password	Confirm the password by retyping it here.
Node Name	Specify the name of the BOBI node being monitored.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Connections	Indicates the number of connections currently open on the semantic layer.	Number	This is a good indicator of the current connection load on the layer.
OLAP connections	Indicates the number of OLAP connections currently open on the semantic layer.	Number	This is a good indicator of the current OLAP connection load on the layer.
Sessions	Indicates the number of open sessions between clients and the layer.	Number	This is a good indicator of the current session load on the layer.
Data requests	Indicates the number of currently open data requests between clients and the layer.	Number	A consistent increase in the value of this measure could indicate that requests are not been processed quickly enough by the server. You may have to investigate the reasons for this bottleneck and fix it.
