Expert Functions

There are a number of additional functions for the Gateway Monitor that you can use for monitoring and analysis. To access these functions, choose Goto Expert functions .

Prerequisites

The initial screen of the Gateway Monitor is open.

Features

The following functions are available:

Function	Use
Load balance table	Displays the load balancing table when Load Balancing for Registered Programs is in use.
Network addresses	Displays all network addresses of the current host. Also tells you where the names were taken from.
Host Name Buffer	The host name buffer buffers the assignments of IP addresses to host names. This enhances performance during connection establishment. This function can display the host name buffer, write it to a file, or reset it.
Statistics	Allows you to check the performance of the SAP Gateway. You can activate and deactivate these statistics dynamically. Resetting the statistics causes all the data currently gathered to be deleted and the statistics to be deactivated. To call up the statistics functions, choose ® Goto Expert functions Statistcs . You can display, activate, deactivate, or reset the statistics. The statistics display includes the following values: Timeout count Request block overflow count Request count (read and work processes) Total request time (read and work processes) Time per request (minimum, mean, maximum for read and work processes) Longest request (read process) TCP statistics CPI-C statistics
External security	Here, you can: Display the security files secinfo and reginfo Read the security files again This allows the security information to be modified during the runtime of the gateway. For more information, see: Security Settings in the SAP Gateway
Started programs	Displays the list of started programs (see the parameter description for `gw/startup` in Parameterization of the SAP Gateway).
Logging	Configuration and display of gateway logging (see Setting Up Gateway Logging)
GW WP status	You get a list of all work processes of the instance with detailed information about their status regarding the gateway.
List of the Conversation IDs	You can see all the conversion IDs that the gateway manages: includes conversation IDs created by other gateways, and which communicate with the local gateway, as well as conversation IDs generated by the local gateway. `local, conn=nn` means this conversation ID was created by the local gateway and is assigned to the connection with the number `nn`. You can see this conversation ID in the list of active connections (initial screen of SMGW). `remote, host / serv (gw_id=xx)` means this conversation ID was created by the remote gateway on the host <host>, service <serv>. This remote gateway is listed in the 'remote gateways' list under number xx (Displaying Remote Gateways).
Soft Shutdown	Soft shutdown terminates the gateway –the gateway accepts no new connections and closes as soon as there are no more active connections.
Hard Shutdown	The hard shutdown terminates the gateway immediately (no checks made).
