6.5 Creating Exalogic Reports in Enterprise Manager

You can create the following Exalogic reports in Enterprise Manager:

  • Oracle BI Instance Performance -- This report covers all BI instances running on the selected Exalogic rack. First a list of all WebLogic domains associated with the selected Exalogic rack is read, then all oracle_ias_farm targets associated with those WebLogic domains are determined and then the list of all BI instances associated with those oracle_ias_farm targets are identified.

  • Oracle Internet Directory Performance -- This report covers all OID servers running on the selected Exalogic rack. First a list of all WebLogic domains associated with the selected Exalogic rack is read, then all oracle_ias_farm targets associated with those WebLogic domains are determined and then the list of all OID servers associated with those oracle_ias_farm targets are identified.

  • Oracle Service Bus Performance -- This report covers all OSB servers running on the selected Exalogic rack. First a list of all WebLogic domains associated with the selected Exalogic rack is read and then all OSB server targets associated with those WebLogic domains through ‘farm' association are identified. This report has two sections under each OSB server – Top Business Services and Top Proxy Services. These sections show the top five business services and the top five proxy services respectively. The top five services are determined based on the decreasing order of max value of throughput (for example, messages per minute) metric for each service during the selected period.

  • SOA Infrastructure Performance -- This report covers all SOA Infrastructure targets running on the selected Exalogic rack. First a list of all WebLogic domains associated with the selected Exalogic rack is read and then all SOA Infrastructure targets associated with those WebLogic domains through ‘farm' association are identified. The SOA Infra Engine related charts cover only the following four engine types - bpel, bpmn, mediator and workflow.

  • Oracle WebLogic Server Performance -- This report covers all WebLogic servers running on the selected Exalogic rack. The list of all WebLogic domains associated with the selected Exalogic rack is read. The report is divided into sections based on different WebLogic domains. For each domain, the top five servers are shown in the charts for each metric. The top five servers for each metric are determined by decreasing order of max value for the metric for each server in the selected period.

  • Compliance Summary -- This report give a brief summary about the compliance standards evaluated for the middleware targets like WebLogic server, domains, clusters, host, and so on, running on the Exalogic system. The report shows the list of top ten least compliant WebLogic domains and host and Compliance Standard Summary.

  • Compliance Details -- This report give details on about the compliance standards evaluated for middleware targets like WebLogic domains, servers, clusters, hosts, and so on, running on the Exalogic system. The reports show the top ten least compliant WebLogic domains and host and a detailed list on compliance rules violated for the middleware targets.

The Reports menu item is visible in the Exalogic system menu if BIP is configured with Enterprise Manager. If BIP is not configured, the menu item does not appear.

To create Exalogic reports, follow these steps:

  1. From the Targets menu, select Exalogic.
  2. From the list of Exalogic targets, click the Exalogic Elastic Cloud target for which you want to create reports.
  3. From the Exalogic Elastic Cloud menu, choose Reports and then select the report you want to create from the menu.
