Gateway Monitor - Transaction SMGW

The Gateway Monitor (transaction SMGW) is used for analyzing and administrating the gateway in the SAP system.

You can launch the Gateway Monitor via transaction SMGW or by choosing the following menu path: Start of the navigation path Administration Next navigation step System Administration Monitor System Monitoring Gateway Monitor End of the navigation path

You can still continue to run the gateway monitor at operating system level from outside the SAP system. Use program gwmon.exe for this.

The initial screen of the gateway monitor shows all the active gateway connections on this application server instance.

Tip You can switch application server instance in transaction SM51.

Tip If there is also a gateway configured on the ASCS instance, you can access its administration functions from the following menu path: Start of the navigation path

Goto

ASCS Gateway Monitor End of the navigation path

The columns in the gateway monitor on the initial screen in the default setting have the following meaning:

Column	Explanation
`Number`	Number to identify the connection.
`Local LU Name`	Host on which the local partner program is running or is to run.
`Local TP Name`	Long transaction program name, or the name of the local program that was started by the gateway. If it is an ABAP program (protocol: internal communication), you can see the service (port) of the local gateway here.
`Remote LU Name`	Host on which the remote partner program is running or is to run.
`Remote TP Name`	Long transaction program name or the name of the remote program that was started by the gateway. If it is an ABAP program (protocol: internal communication), here you can see the service (port), which the program communicates with.
`User`	Name of the user who is currently using the connection
`Status`	This field indicates the status of the connection: It can have the following values: `unused`: Connection is not being used `Initial`: Connection is being initialized `Initializing`: Connection initialized `Connecting`: Connection is opening `Connected`: Connection is made `Is being interrupted`: Connection to be closed down `Interrupted`: Connection closed down
`Symbolic destination`	The symbolic destination is required when CPIC connections are set up and is a key for the TXCOM and side information tables. These tables manage the required connection parameters. First the system attempts to read unknown parameters from table TXCOM. Afterwards the Gateway reads all the parameters not defined in this table from the side information.
`Conversation ID`	The conversation ID is a unique number that can be used to identify the connection. By clicking this field, you can display details of the connection.
`Protocol`	This field indicates the protocol agreed with the client: The following values are possible: `Internal Communication`: Communication partner is an ABAP program (the same or a different SAP system) `External Communication`: Communication partner is an external program `Registered Communication`: External communication with registered program
`Last Request`	Time of last activity
`SAP Error`	SAP return value: These return values are defined by SAP; you can display an overview in F1 help. The previous and following syslog messages provide further details on the source of the error. If the syslog messages are not sufficient, the relevant trace files must be analyzed. The return codes are described under Error Analysis.

You can add the following columns to the gateway monitor from the column set:

Table 1: Optional Columns of the Gateway Monitor
Column	Explanation
Connection Status	Status of the connection to a client or another gateway at TCP/IP level. The default value is CONNECTED.
Protocol	This field indicates the protocol agreed with the client:
Request	Timestamp of the last request that was processed in this connection.
