32 Investigating and Analyzing Problems

This section explains how to use the Problem Analysis and Analyze Log pages to investigate and analyze problems.

Specifically, these pages enable you to inspect metrics, target status information, incidents, and logs during troubleshooting.

32.1 Accessing Problem Analysis and Logs

There are several navigation methods to access problem analysis and log pages:

  • Middleware access method

    1. From the Targets menu of the Cloud Control console, select Middleware.

    2. Select and click on an Oracle Access Manager Server or Oracle WebLogic Server from the Details Table.

    3. In the home page that appears, click on a metric legend that appears below the Response and Load chart.

    4. In the pop-up that appears, click on Problem Analysis or Log Messages.

  • Incident Manager access method

    1. From the Targets menu of the Cloud Control console, select Hosts.

    2. Click a numbered link in the Incidents column of the summary table.

    3. In the Incident Manager page that appears, select an incident in the table, then click on the Problem Analysis link located in the Diagnostics section in the lower right portion of the page.

    4. In the pop-up that appears, click on Problem Analysis.

  • Correlation charts method

    Correlation charts are the pages in which the charts are shown as a stack of charts.

    1. From any correlation chart, click on the chart legend.

    2. In the pop-up that appears, click on Problem Analysis or Log Messages.

  • Chart regions method

    1. Click on the chart legend or chart line.

    2. In the pop-up that appears, click on Problem Analysis or Log Messages.

32.2 Viewing and Analyzing Problems

You can inspect metrics, status information, and logs using Cloud Control as follows:

  1. Specify the time period for which you want the charts to display data. Near the top of the default Related Metrics tab, adjust the left and right slider to specify the time period, or click and drag within a metric chart to indicate the time period you want to inspect.

  2. Inspect the charts for unusual increases in recorded metrics.

    • Out of the box, Enterprise Manager provides two charts: Source Metric and Enterprise Manager Identified Related Metrics. You can add more chart displays to suit your needs by using the Metric Palette. See "Customizing the Display" below for more information.

    • Increased request processing time due to a high number of requests per minute may indicate a need to increase the capacity of your system.

  3. If the metric charts do not indicate the cause of the problem, select the Related Targets tab and inspect the table for information about target health (status) and recent configuration changes.

    If you want to see a reminder of the topology of the components for which data is being displayed, click the Topology tab.

  4. If the table does not indicate the cause of the problem, return to the Related Metrics tab and click on the View Related Log Messages link near the top of the tab. This action displays log messages for the selected target and its members during the selected time period.

  5. Inspect any log messages that are displayed for possible causes of problems.

32.3 Customizing the Display

You can create your own metric charts and then recall them later when needed.

  1. From the Metric Palette on the Related Metrics tab, select a target from the Targets pane, then select the desired metrics associated with the target from the Metrics pane.

    A new region called User Identified Related Metrics appears in the lower portion of the page, and displays a chart for each metric you have selected in the Metric Palette.

  2. Optional: Save any modifications to the current chart by clicking Save.

    You can also save your modified chart to Enterprise manager and have it appear as a choice in the Charts Sets menu for recall at a later time. To do so, select Save Charts As... from the Chart Sets menu, then name the chart and click OK.

    You can also set this chart as the default chart that appears when you access this page by selecting Set as Default Chart Set from the Chart Sets menu.


    If you prefer seeing the chart data in a tabular format, you can click the Table View link below the last chart.
