SAP Web Dispatcher Connections Test

As a “software web switch”, the SAP Web dispatcher can reject or accept connections. When it accepts a connection, it balances the load to ensure an even distribution across the servers. The SAP Web Dispatcher therefore contributes to security and also balances the load in your SAP system. Often administrators are required to identify the number of connections made to the SAP Web Dispatcher and figure out how often such connections are made. The SAP Web Dispatcher Connections test helps administrators in this regard!

For each protocol type, this test reports the number of connections made to the target SAP Web Dispatcher and the maximum time taken by a connection. Using this test, administrators can figure out the protocol type through which maximum number of connections are made and identify the maximum time duration that is required for a connection to be established.

Target of the test : A SAP Web Dispatcher

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each protocol type of connections made to the SAP Web Dispatcher that is being monitored .

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

Specify the host for which the test is to be configured.

Port

The port number at which the specified host listens. The default is 2375.

WEB Dispatcher DIR

Specify the full path to the directory where the target SAP Web Dispatcher is installed.  Ensure that the location specified contains the sapwebdisp and wdispmon executables.

Profile File

Specify the full path to the profile file with which the target SAP Web Dispatcher was started. The default name of the profile is sapwebdisp.pfl.

Timeout

Specify the time for which the eG agent should wait for collecting the required metrics. By default, this is 60 seconds

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Number of connections

Indicates the total number of connections of this protocol type made to the SAP Web Dispatcher.

Number

This measure is a good indicator of the load on the SAP Web Dispatcher.

Comparing the value of this measure across the protocol types will enable you to figure out the protocol type that tops the maximum number of connections.

Maximum time for a connection

Indicates the maximum time taken to establish a connection of this type.

Mins

The detailed diagnosis of this measure if enabled, lists the Top 3 slowest connections of each protocol type along with connection ID, Request type, address, connection time, timeouts etc.
