本文說明如何解決在 Workload Manager 中使用 SAP 工作負載可觀測性服務時可能遇到的問題。
可觀測性資訊主頁未列出 SAP 系統 ID
設定 Google Cloud's Agent for SAP 以進行可觀測性作業，並授予服務帳戶所有 VM 的必要權限 (這些 VM 裝載 SAP 系統的不同元素，例如中央服務、應用程式伺服器和 SAP HANA 資料庫) 後，系統 ID 就會顯示在 SAP 可觀測性資訊主頁上。如果系統 ID 未列出，請按照下列章節的說明，檢查代理程式設定和記錄。
在「系統總覽」頁面中，檢查系統是否正確識別架構和規模類型。如果這兩個參數有任何一個或全部不正確，則表示Google Cloud的 SAP 代理程式或上傳至 Google Cloud的 SAP 資料有潛在問題。如需進一步分析，請與 Cloud Customer Care 團隊聯絡。請參閱「取得 Google Cloud的 Agent for SAP 支援」。
由於指標 workload/sap/nw/instance/role 或 workload/sap/hana/ha/availability 無法正常運作或遺失，系統無法正確識別與 VM 相關的角色。在「應用程式和資料庫」資訊主頁的 VM 清單中，檢查已識別的 SAP 角色。
以下是各架構類型所需的角色：
集中式架構：核心服務、應用程式伺服器和 SAP HANA 主要伺服器。
分散式架構：核心服務、應用程式伺服器和 SAP HANA 主要伺服器。
分散式架構 (具備高可用性)：核心服務、ERC、應用程式伺服器、SAP HANA 主要伺服器和 SAP HANA 次要伺服器。
清單中的所有 VM 都應指派角色。
請檢查 Cloud Monitoring 中的指標，或使用 timeSeries API 方法，讓 Agent for SAP 推送最新值，確認必要指標具有有效值。如果 Cloud Monitoring 中沒有該指標，或該指標沒有值，則健康狀態會標示為「未指定」，因為資料不足，無法評估該指標。

If the system ID is not listed, check the\nagent configuration and logs as explained in the following sections.\n\n### Verify the agent configuration\n\nYou must ensure that all required features are correctly configured for the\nGoogle Cloud's Agent for SAP.\n\nTo get the status of the features of your agent instance, run the following command: \n\n sudo /usr/bin/google_cloud_sap_agent status\n\nThis command output summarizes the enabled and disabled features. It also\nindicates any missing IAM permissions or configuration issues.\nFor more information, see [Validate the setup for Workload Manager observability](/workload-manager/docs/observe/sap/configure-agent#validate-setup).\n\n### Check the VM instance logs\n\nIn the VM instance logs, view issues related to the Agent for SAP not being able to update the SAP system information.\nTo view logs, do the following:\n\n1. Select a VM to open the **Details** page.\n2. Click the **Observability** tab to display information about the VM.\n3. Select **All logs** and sort by Error as the **Severity**.\n\n Most of these errors are related to missing permissions for the service account\n attached to the VM. To resolve these errors, [grant the required permissions](/workload-manager/docs/observe/sap/prerequisites#service-account)\n to the service account.\n\n### Check logs using Cloud Logging\n\nYou must ensure that the Agent for SAP discovers your SAP workloads correctly.\nTo view log entries for the VM instance that hosts the agent, do the following:\n\n1. In the Google Cloud console, select **Logging** , and then select **Logs Explorer**:\n\n [Go to the Logs Explorer](https://console.cloud.google.com/logs)\n2. In the **Query** pane, select **Show query** and enter the following query:\n\n ```\n jsonPayload.@type:\"SapDiscovery\"\n ```\n\n If you cannot see any information from the VMs that host the agent, then the\n agent might not be configured or working properly. For more information,\n see [Configure Agent for SAP](/workload-manager/docs/observe/sap/configure-agent).\n3. Optional: To view logs related to the process when Agent for SAP\n uploads the SAP discovery data, use the following query:\n\n ```\n -jsonPayload.caller=~\"third_party/sapagent/internal/system/clouddiscovery/cloud_discovery.go\"\n -jsonPayload.caller=~\"third_party/sapagent/internal/system/sapdiscovery\"\n ```\n\nHealth status appears as unspecified\n------------------------------------\n\nThere might be multiple root causes for *Unspecified* (gray color) health status\nof the SAP system. This health status is used to identify systems that cannot\nbe correctly evaluated by Workload Manager due to missing metrics or settings.\nThe most common causes for this health status are as follows:\n\n- The Google Cloud's Agent for SAP might be stopped or incorrectly\n reporting the required metrics. For more information, see [Validate your installation of the agent](/sap/docs/agent-for-sap/latest/install-config-on-vm#validate-agent4sap-installation).\n\n- If Agent for SAP is up and running and the system status is *Unspecified* ,\n check that the [Process Monitoring](/sap/docs/agent-for-sap/latest/process-monitoring) and [SAP HANA Monitoring](/sap/docs/agent-for-sap/latest/monitoring-sap-hana) features are enabled and configured\n correctly in the agent depending on the SAP processes running on the VM.\n Central Services and Application Servers require Process Monitoring to be enabled\n while SAP HANA databases require Process Monitoring and SAP HANA Monitoring enabled.\n\n - The default values for the [collection frequency](/sap/docs/agent-for-sap/latest/process-monitoring#pm_metric_types) of the fast-changing and slow-changing Process Monitoring metrics are 5 seconds and 30 seconds respectively. If these values are increased above the default values, you might see the health status as *Unspecified*.\n- On the System overview page, check whether the **Architecture** and **Scale-Type**\n are correctly identified for your system. If any or both of these parameters\n are incorrect, then there is an underlying issue with either the\n Google Cloud's Agent for SAP or the uploaded SAP data to Google Cloud.\n For further analysis, contact Cloud Customer Care. See [Getting support\n for Google Cloud's Agent for SAP](/sap/docs/agent-for-sap/latest/troubleshooting#getting_support_for_agent).\n\n- The roles for each VM related to the system are not correctly identified due\n to the metrics `workload/sap/nw/instance/role`\n or `workload/sap/hana/ha/availability` not working correctly or missing.\n Check the identified SAP roles in the list of VMs on the Applications and Databases dashboards.\n\n | **Note:** On the observability dashboards, the *role* for a VM represents the SAP service hosted on that VM.\n\n The following roles are required for each of the architecture types:\n - Centralized Architecture: Central Services, Application Server, and SAP HANA Primary.\n - Distributed Architecture: Central Services, Application Server, and SAP HANA Primary.\n - Distributed with HA: Central Services, ERC, Application Server, SAP HANA Primary, and SAP HANA Secondary.\n\n All the VMs in the list should have a role assigned to them.\n- Verify that [the required metrics](/workload-manager/docs/observe/sap/view-dashboards#metrics) have a valid value by either checking\n the metric inside Cloud Monitoring or by using the [timeSeries](/monitoring/api/ref_v3/rest/v3/projects.timeSeries) API method\n to have the latest value pushed by the Agent for SAP. If the metric is not present in Cloud Monitoring or has no value,\n then the health status is marked as *Unspecified* because there is not enough data to evaluate such a metric.\n\n- On Distributed with HA architectures, check if there is a failed action\n in the cluster and perform a cleanup by running the following commands:\n\n ### RHEL\n\n ```sh\n pcs resource cleanup RESOURCE_ID\n ```\n\n ### SLES\n\n\n ```sh\n crm resource cleanup RESOURCE_ID\n ```\n\n \u003cbr /\u003e\n\n Replace \u003cvar translate=\"no\"\u003eRESOURCE_ID\u003c/var\u003e with the ID of the failed resource\n in the cluster.\n\n Failed action in the cluster might impact the metrics `workload.googleapis.com/sap/cluster/nodes`\n and `workload.googleapis.com/sap/cluster/resources` and it reports incorrect values.\n- Check whether the Google Cloud's Agent for SAP version is up to date and that\n you are running the latest version available. Newer versions of the\n agent contains fixes for issues and bugs related to observability metrics.\n Incorrect metrics might result in the *Unspecified* health status of the system.\n\n- For SAP HANA databases replicating to a secondary site, check if there is a valid cluster configuration between primary and secondary."]]
