RFC Configuration Test

The RFC server is responsible for the communication between an SAP system and the TREX servers.

The SAP system sends requests to an RFC server using an SAP Gateway. The RFC server converts the requests to a TREX-internal format and then forwards them to the corresponding TREX servers. The TREX configuration depends on the structure of the SAP system. The TREX RFC Servers can be configured either in single-thread mode or in multi-thread mode. In the case of TREX RFC servers in single-thread mode, there are at least as many RFC servers (instances/processes) running on each TREX host as there are application servers. In the case of TREX RFC servers in multi-thread mode, exactly one RFC server (instance/process) runs on each TREX host and within this one RFC server, at least as many threads are started as there are applications servers. The TREX configuration depends on the structure of the SAP system. Each TREX host runs at least as many TREX RFC servers as there are application servers. If application servers are added to or removed from the SAP system, the TREX configuration should be changed accordingly. If the TREX configuration is not changed, then the communication between the RFC server and the SAP system may be disconnected. To avoid such disconnects, it is essential to monitor the configuration of the RFC server continuously. The RFC Configuration test helps administrators in this regard!

Using this test administrators can figure out the current configuration status of the RFC server with the target TREX server instance, the status of the RFC server and the number of threads configured on the RFC server.

Target of the test : A SAP TREX

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the SAP TREX server that is to be monitored

Configurable parameters for the test

TEST PERIOD - How often should the test be executed Host – The host for which the test is to be configured. PORT - Specify the port at which the specified HOST listens. TREX DIRECTORY - Specify the full path to the SAP TREX instance that is to be monitored for e.g., the location can be specified as D:\usr\sap\TRX\TRX01. TIMEOUT - Specify the duration (in seconds) beyond which this test should time out in the TIMEOUT text box. The default is 120 seconds. DETAILED DIAGNOSIS - To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measures made by the test:

Measurement	Description	Measurement Unit	Interpretation
RFC configuration status:	Indicates the current configuration status of the RFC server with the SAP TREX instance.		The values reported by this measure and its numeric equivalents are mentioned in the table below: Measure value Numeric Value Success 0 Warning 1 Error 2 Note: By default, this measure reports the Measure Values listed in the table above to indicate the current configuration status of the RFC server with the SAP TREX instance. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 to 2.
RFC server status:	Indicates the current state of the RFC server i.e., indicates whether the RFC server and the associated threads of the server are configured to run properly.		The values reported by this measure and its numeric equivalents are mentioned in the table below: Measure value Numeric Value Success 0 Warning 1 Error 2 Note: By default, this measure reports the Measure Values listed in the table above to indicate the current configuration status of the RFC server with the SAP TREX instance. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 to 2. The detailed diagnosis of this measure lists the errors encountered by the RFC server.
Reachable destinations:	Indicates the number of RFC threads that are configured for the RFC server.	Number
