SAP WAS Sessions Test

This test reports metrics pertaining to user sessions on the SAP web application server as revealed by the Security Provider service. This service enables the management of the security policy and the authentication and authorization mechanisms on the system, monitors user sessions, and restricts access to the resources or the applications deployed on the J2EE Engine.

Target of the test : A SAP NetWeaver Application Server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each of the Dispatchers and each of the configured server processes of the SAP Web AS.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed
Host	Specify the server for which the test is to be configured.
Port	The port number at which the specified server listens.
UserName	This test connects to a specific SAP web application server instance, and extracts critical metrics from it. Therefore, in the UserName text box, provide a valid j2ee admin user name which the test should use for connecting to the server instance.
Password	Provide the Password that corresponds to the specified UserName.
Confirm Password	Confirm the OS Password by retyping it here.
InstanceName	Provide the name of the application server instance to which the test should connect. For example, if you specify tpp here, then the test will use the login credentials (UserName and Password) provided here to connect to an instance named TPP. To know the available server instances, use the instructions provided in Determining the Name of the SAP Web AS Instance.
ConnectorPort	This test uses the P4 protocol for connecting to the SAP web application server. Therefore, the port at which the P4 protocol listens needs to be specified as the ConnectorPort. To know how to determine the P4 port, use the procedure detailed in Determining the P4 Port.
DispatcherID	This test reports a set of metrics for the Java dispatcher that receives client requests. By default, the cluster ID of the dispatcher is auto-discovered by the eG Enterprise. Therefore, default option is specified against this parameter. Alternately, if you wish to monitor a specific cluster ID, then you can mention that cluster ID against this parameter. To know the cluster ID of the dispatcher, follow the steps discussed in Determining the Name of the SAP Web AS Instance and P4 Protocol Port .
ServerIDs	Typically, the Java dispatcher or the ICM distributes the client requests it receives to the server processes executing on the Java component of the SAP Web AS for processing. By default, the ServerIDs are auto-discovered by the eG Enterprise. To monitor specific server processes, specify a comma-separated list of the cluster IDs of these server processes in the ServerIDs text box. To know the cluster IDs of the server processes, follow the procedure detailed in Determining the Name of the SAP Web AS Instance and P4 Protocol Port. Providing a comma-separated list of server process cluster IDs will ensure that these cluster IDs alone appear as the descriptors of the test. If need be, you can have server process name-cluster ID pairs appear as the test descriptors. To achieve this, the specification in the ServerIDs text box should be of the following format: Server process name:Cluster ID of the server process. For example, if the cluster ID of a server process named Server0 is 12621850, then you can specify the ServerID in the format: Server0:12621850.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Failed logon attempts	Indicates the number of unsuccessful logon attempts since the last measurement period.	Number
New sessions	Indicates the number of sessions that have newly opened since the last measurement period.	Number
Active sessions	Indicates the number of currently active sessions.	Number
Invalid sessions	Indicates the number of invalid sessions since the last measurement period.	Number
Logged off sessions	Indicates the number of sessions users logged out of since the last measurement period.	Number
Timed out sessions	Indicates the number of sessions that timed out.	Number	If the value of this measure is very high, then consider resetting the Timeout period for user sessions.
Logged in users	Indicates the number of users logged in since the last measurement period.	Number
Opened sessions	Indicates the number of web sessions that were opened during the last measurement period.	Number
Active web sessions	Indicates the number of web sessions that were active during the last measurement period.	Number
Security sessions	Indicates the number of security sessions opened during the last measurement period.	Number	Security sessions are objects that store authentication information for users for their various HTTP sessions. Each security session corresponds to at least one HTTP session. If a security session is invalidated, so are the associated HTTP sessions.
EJB sessions	Indicates the number of EJB sessions opened during the last measurement period.	Number	EJB sessions are Enterprise JavaBean sessions which may be stateful (bean state is preserved and stored across method invocations) or stateless (bean state is not preserved across method invocations).
