ABAP Instance Memory Test
This test monitors the basic functions of the SAP Memory Management System and advises on how best to configure the system depending upon the platform used, the available resources, etc. It also sheds light on the hardware and operating system usage.
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 every SAP ABAP instance being monitored.
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 |
Password |
The password of the specified SAPUser. |
Confirm Password |
Confirm the password by retyping it here. |
SysNo |
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 |
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 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 INSTANCE 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. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Heap memory total allocation |
The total size of heap memory (private memory). |
MB |
|
Heap memory actual usage |
The percentage of heap memory actually used. |
Percent |
Heap memory is a local memory assigned for the work process in SAP. Heap memory contains user contexts. Typically, if a dialog work process fully utilizes the extended memory, it starts . Once the heap memory is assigned to a work process, the work process will switch to the PRIV mode. This means that the work process is reserved for processing the current user context until the context releases the work process again when the request has ended. If this measure reports a non-zero value, it implies that heap memory has been used – i.e., one/more work processes are in the PRIV mode. For best performance, not too many dialog work processes should be in the PRIV mode simultaneously. |
Extended memory allocated |
Indicates the total size of the extended memory. |
MB |
|
Extended memory actual usage |
The actual usage of extended memory. |
