SAP S/4HANA (Single-Node Deployment Without High Availability Required)

Prerequisites

Ensure that Application Operations Management (AOM) ICAgent has been installed.

• AOM ICAgent is used to collect host OS metrics, such as CPU, memory, and disk. If it has not been installed, install it by referring to Installing an ICAgent.

Ensure that the AOM FullAccess permission has been assigned to the agency created for the host.

• AOM FullAccess is used for the authentication of AOM metric reporting API. The following describes the procedure to configure the permission.

1. Log in to the management console.
2. In the navigation pane on the left, click and choose Identity Access Management under Management & Governance.
3. Click Agencies in the left pane, and then click Create Agency in the upper right corner. The Create Agency page is displayed.
4. Set agency parameters.
   • Agency Name: AOMFullAccess (this name is only for reference)
   • Agency Type: Select Cloud service.
   • Cloud Service: Select Elastic Cloud Server (ECS) and Bare Metal Server (BMS).
   • Validity Period: Retain the default setting.
   • Click Next to configure the permission:
     1. Select Region-specific projects for Scope.
     2. Select the region where the cloud server is located.
     3. Enter AOM FullAccess in the search box and select it in the search result.
     4. Click OK.

5. Configure the agency created in the previous step for the ECS.
   1. In the left navigation pane, click and choose Computing > Elastic Cloud Server.
   2. Select the ECS for which you want to configure the agency and click its name to switch to the basic information page.
   3. Click the edit button next to Agency in the Management Information area, select the agency created in 4, and save the modification.

Procedure

Preparations

1. Obtain SAP NW RFC SDK.
   

   To obtain SAP NW RFC SDK, log in at https://support.sap.com/en/my-support/software-downloads.html, access downloads of Support Packages & Patches, search for SAP NW RFC SDK 7.50, and download it.

2. Log in to the cloud server as user root.
3. Upload the obtained SAP NW RFC SDK installation package to the /usr/sap directory.
4. Run the following commands to decompress the SAP NW RFC SDK package to the /usr/sap directory:

   unzip nwrfc750P_7-70002752.zip

   mv nwrfcsdk /usr/sap/

Installing the Monitoring Agent

1. Run the following commands to obtain the installation script to install the monitoring agent.

   The download paths of the script vary depending on regions. For details about how to obtain the path, see Table 1. The following commands show the download path in AP-Bangkok.

   cd /tmp

   wget https://obs-sap-ap-southeast-2.obs.ap-southeast-2.myhuaweicloud.com/sapmon/install.sh&& sh install.sh --nwrfcsdk-path /usr/sap/nwrfcsdk

   /usr/sap/nwrfcsdk is the decompression path in 4.

   Table 1 Link to obtain the installation script

   Script Name	Description	Download Link
   install.sh	Installation script	AP-Bangkok: https://obs-sap-ap-southeast-2.obs.ap-southeast-2.myhuaweicloud.com/sapmon/install.sh AP-Singapore: https://obs-sap-ap-southeast-3.obs.ap-southeast-3.myhuaweicloud.com/sapmon/install.sh CN-Hong Kong: https://obs-sap-ap-southeast-1.obs.ap-southeast-1.myhuaweicloud.com/sapmon/install.sh SA-Johannesburg: https://obs-sap-af-south-1.obs.af-south-1.myhuaweicloud.com/sapmon/install.sh TR-Istanbul: https://obs-sap-tr-west-1.obs.tr-west-1.myhuaweicloud.com/sapmon/install.sh LA-Santiago: https://obs-sap-la-south-2.obs.la-south-2.myhuaweicloud.com/sapmon/install.sh LA-Sao Paulo1: https://obs-sap-sa-brazil-11.obs.sa-brazil-1.myhuaweicloud.com/sapmon/install.sh LA-Mexico City1: https://obs-sap-na-mexico-1.obs.na-mexico-1.myhuaweicloud.com/sapmon/install.sh LA-Mexico City2: https://obs-sap-la-north-2.obs.la-north-2.myhuaweicloud.com/sapmon/install.sh

2. Modify the configuration.
   1. Run the following command to encrypt the password:

      /usr/local/sapmon/bin/ktool -e

   2. Enter the password.
   3. Run the following command to enter the edit mode of the configuration file. Modify the file according to Table 2, save the file, and exit.

      vim /usr/local/sapmon/config/sapmon.ini

      Modify the parameters based on the actual situation. Change the password to the return code obtained in 2.a.

      Table 2 Configuration parameters

      Parameter Type	Name	Description	Example Value
      DEFAULT	log_level	Log level	INFO
      	log_file	Log file name. The log file path is /var/log/huawei/sapmon/.	sap_metrics.log
      	hostname	OS hostname	s4hana-1709
      application.netweaver	enable	Whether to obtain the application metrics. The value can be true or false. NOTE: In the SAP S/4HANA (single-node deployment with HA required) scenario, set this parameter to true for the active node and to false for the standby node.	true
