Dialog Activity Test

The Dialog service is the one which responds to the user requests to an SAP ABAP server. This test reports performance statistics pertaining to the Dialog service of the SAP ABAP server.

Target of the test : A SAP ABAP instance

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the SAP ABAP instance being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed

Host

Host name of the server for which the test is to be configured.

PortNo

Enter the port to which the specified host listens.

ClientName

Specify the ID of the client system as what the eG agent will be connecting to the SAP ABAP instance. To know how to determine the client ID to use, follow the instructions provided in Determining the Client ID/Name for the eG Agent to Connect to the SAP ABAP Instance.

SAPUser

Typically, to connect to a SAP ABAP instance and run tests, the eG agent requires the permissions of a SAP user who has been assigned with certain authorization objects. Ideally, you will have to create a new user role on the SAP ABAP instance for this purpose, associate the above-mentioned authorization objects with that role, and assign the new role to an existing SAP user. The procedure for the same has been provided in Creating a New User Role for Monitoring and Assigning it to a SAP User. Once the new role is assigned to a SAP user, specify the name of this user against SAPUser.

Password

The password of the specified SAPUser.

Confirm Password

Confirm the password by retyping it here.

SysNo

This parameter appears only if the Use SAPControl flag is set to No – i.e., if the test uses SAPJCO to collect measures. An indicator of the TCP/IP port at which the SAP server listens. For example, for a server that listens at port 3200, the SysNo will be ‘00’. Similarly, if the SAP server port is 3201, the SysNo will have to be specified as ‘01’. Therefore, in the SysNo text box specify the system number of the SAP server with which the specified client communicates. To know the system number for the ABAP server being monitored, follow the procedure detailed in Identifying the SAP Router String and System Number.

Router

This parameter appears only if the Use SAPControl flag is set to No – i.e., if the test uses SAPJCO to collect measures. If the SAP client with the specified ClientName exists in a network external to the SAP server, then a router will be used to enable the server-client communication. In such a case, specify the router string of the router in the Router text box. If both the client and the server exist in the same network, then specify ‘none’ against the Router text box. To know what is the SAP Router string for the ABAP server being monitored, follow the procedure detailed in Identifying the SAP Router String and System Number.

InstanceName

This parameter appears only if the Use SAPControl flag is set to No – i.e., if the test uses SAPJCO to collect measures. This is set to none by default. This implies that the eG agent automatically discovers the instance name at run time.

Timeout

Indicate the duration (in seconds) for which this test should wait for a response from the SAP ABAP instance. By default, this is set to 120 seconds.

JCO Version

The eG agent uses the SAP JCO library to connect to the SAP ABAP system and pull out metrics. To enable the eG agent to make this connection and query the metrics, you need to specify the version of the SAP JCO library that the agent needs to use. For instance, to instruct the eG agent to use JCO v2.1.19, it would suffice if you specify the ‘major version number’ alone against JCO Version – in the case of this example, this will be 2.x. Note that if you have downloaded the SAP JCO CONNECTOR files for SAP JCO version 3 from the SAP market place (as instructed by Downloading the SAP JCO Connector files Required for Monitoring ), then the JCO Version configuration should be 3.x. 

IsPassive

If the value chosen is Yes, then the server under consideration is a passive server in a SAP ABAP cluster. No alerts will be generated if the server is not running. Measures will be reported as “Not applicable” by the agent if the server is not up.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Utilization of the dialog processes

The percentage utilization of the dialog work processes of an application server.

Percent

 

Dialog work processes

The number of dialog work processes.

Number

 

Dispatcher wait queue length

The percentage utilization of the dispatcher wait queue.

Percent

With normal workload, this value is around 0%. A long wait queue is a sign that the application server has too few work processes or too high a CPU workload.

Long runners

Indicates how long the long-running dialog processes have been running.

Secs

Long-running tasks can block other users’ dialog steps and can produce a general degradation of dialog response time for interactive users. Resolving this problem requires analysis of long-running dialog steps. Corrective measures include moving users to another application server, asking users to schedule long-running reports or other actions as background jobs in off-peak time periods, etc.

Dialog steps

The number of dialog steps per minute.

Steps/min

A high value combined with a high Dialog process time points to a general overload; a very low value, indicates an error.

Users logged in

The number of users logged in.
