Viewing Performance Metrics for an Oracle Cloud Service

For some Oracle Infrastructure and Platform Cloud Services (Oracle IaaS/PaaS), you can monitor real-time service usage data to help you determine whether the resource allocations for a service are underutilized or overutilized. You can also set alerts, and monitor current and historical usage data for service instances. The graphs in this page are rendered in the time zone you set in the Preferences page.

To monitor usage metrics:

1. Sign in to Infrastructure Classic Console.
2. Navigate to the appropriate page and find the service for which you want more information.
3. Click the service name to open the details page for the service.
   The Overview page is in focus.
4. Click the Monitoring Metrics tab to review usage data for the selected service. This page displays usage data in the form of graphs. The Graph tab displays the related graphs, if any. By default, one graph is displayed with the first metric from each available instance (maximum 3) plotted on the graph. However, each graph can display usage data for a maximum of 5 service instances.

   In this page, you can monitor and customize the following:

   • Show Thresholds/Alerts: Click the button to set alert rules to notify service administrators when a metric is either above or below defined thresholds. This button is displayed only when you select the Graphs tab. See Setting an Alert for a Performance Metric.

   • Viewport/Timeline graph: The graph is divided into a viewport graph and a timeline. Viewport graph displays usage for the selected metric based on the time period set in the timeline. Granular usage data is shown when you set the time range to an hour.

     Drag the slider in the timeline to select a time period. You can also drag the edges of the slider to increase or decrease the selected time period. Usage data is auto-refreshed every minute, when the slider is positioned at the extreme right in the timeline graph. To hide the timeline graph, click Hide Overview.

   • From/To Dates: You can also select specific dates and time from the calendar for a more precise view of metric usage data. By default, the viewport graph displays usage data for the last 2 hours and the timeline displays data up to 1 year (up to the current time), if available. The system calculates and displays usage data based on Coordinated Universal Time (UTC).

   • Add Graph: You can select additional graphs to be displayed in this section by clicking the Add Graph button. This is useful when you want to plot and compare data with the same metric units. By default, 3 metric graphs are displayed. You can select up to a maximum of 4 metric graphs. To remove a metric from the display, click the X icon.

   • Add Metric: You can select additional instances and plot additional metrics on the graph by clicking the Add Metric button below the graph. You can select up to a maximum of 5 instances. To remove a metric, click the X icon. Deleted instances are also displayed in the list and are denoted by an asterisk. You can select a deleted instance to view its historical usage data, however, you can’t select the same within the service tile on the Infrastructure Classic Console.

Your customizations of this page are saved and displayed when you view the Monitoring Metrics page subsequently. However, any customizations to the viewport graph aren’t saved.
