View 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 My Services.
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 Set an Alert for a Performance Metric.

   • Viewport/Timeline graph: The graph displayed at the top is called the viewport graph and shows usage data of the selected metric for the period specified in the timeline graph. Granular usage data is shown when you set the time range to an hour.

     The timeline graph is displayed below the viewport graph and allows you to select a time frame by using a viewport slider. Drag the slider to select a time period. You can also drag the edges of the slider to increase or decrease the selected time period. Usage data of the metric is displayed in the viewport graph according to your selection in the timeline graph. 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 graph displays data up to 1 year before 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 to be displayed within each graph by clicking the Add Metric button below the graphs. You can select up to a maximum of 5 instances. To remove a metric, click the X icon. Customization of the graph and instance display is saved and the same will be displayed when you view the Monitoring Metrics page the next time. However, any customizations to the viewport graph are not saved. Deleted instances are also displayed in the list and 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 My Services dashboard.
