Viewing Instance Metrics

You can view real-time metrics of your Compute Classic instances.

You can access the Monitoring page for your Compute Classic account from the Infrastructure Classic Console. On this page, you can select the type of metric you want to view and to specify up to five instances for each metric. After you configure the metrics that you want to view, the graphs show you the selected metrics for the past two hours for the specified instances. These metrics are automatically updated every minute.

To complete this task, you must have the Compute_Monitor or Compute_Operations role. If this role isn’t assigned to you or you’re not sure, then ask your system administrator to ensure that the role is assigned to you in Oracle Cloud Infrastructure Classic Console. See Modifying User Roles in Managing and Monitoring Oracle Cloud.

To view instance metrics:

  1. Sign in to the Oracle Cloud Infrastructure Classic Console at https://cloud.oracle.com/sign-in.
    The Oracle Cloud Infrastructure Classic Console page is displayed.
  2. Click the Navigation menu icon in the top left corner of the Dashboard.
  3. Click Monitoring.
    The Monitoring Metrics page of the Infrastructure Classic Console opens.
  4. From the list of metrics, select the metrics that you want to see. You can select up to four metrics. The following metrics are available:
    • CPU (%): Indicates CPU utilization in percentage.
    • IOStat Read (sectors): Indicates the average number of sectors read in I/O operations per second.
    • IOStat Write (sectors): Indicates the average number of sectors written in I/O operations per second.
    • Memory Percent (%): Indicates memory utilization in percentage.
    • Memory Usage (KB): Indicates memory utilization in kilobytes.
    • Memory Utilization Percentage (agent): Indicates memory utilization in percentage, as reported by the OPC agent, if the agent is enabled. The memory utilization metrics reported by this agent are more accurate than the memory utilization reported by the Memory Percent metric. When the OPC agent isn’t installed and enabled, no value is displayed. To install and enable the agent, see Enabling Instance Metrics Collection.
    • Memory Utilization (agent): Indicates memory utilization in kilobytes, as reported by the OPC agent, if the agent is enabled. The memory utilization metrics reported by this agent are more accurate than the memory utilization reported by the Memory Usage metric. When the OPC agent isn’t installed and enabled, no value is displayed. To install and enable the agent, see Enabling Instance Metrics Collection.
    • Network Rcvd (B/s): Indicates the average network traffic received by the instance in bytes per second.
    • Network Sent (B/s): Indicates the average network traffic sent by the instance in bytes per second.
    For more information about selecting the instances and metrics that you want to view, see Monitoring Service Usage in Managing and Monitoring Oracle Cloud.

You can also view metrics using the Oracle Monitoring Cloud Service REST API. See Rest API for Oracle Monitoring Cloud Service.
