Viewing Default Metric Charts

This topic describes how to view (Monitoring service) A measurement related to health, capacity, or performance of a given resource. Example: CpuUtilization charts for selected The cloud objects that your company's employees create and use when interacting with Oracle Cloud Infrastructure. or a single resource and create The trigger rule and query to evaluate and related configuration, such as notification details to use when the trigger is breached. Alarms passively monitor your cloud resources using metrics in Monitoring. based on queries used for charts. Charts are available using the Console.

Warning

Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

Prerequisites

  • IAM policies: Viewing metric charts is part of monitoring. To monitor resources, you must be given the required type of access in a An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to the monitoring services as well as the resources being monitored. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization. you should work in. For more information on user authorizations for monitoring, see the Authentication and Authorization section for the related service: Monitoring or Notifications.
  • Metrics exist in Monitoring: The resources that you want to monitor must emit metrics to the Monitoring service.
  • Compute instances: To emit metrics, Compute instances must be monitoring-enabled. OracleCloudAgent software installation may also be required. For more information, see Enabling Monitoring for Compute Instances.

Working with Default Metric Charts

For background information on metrics in Oracle Cloud Infrastructure, see Metrics Feature Overview. For default metrics by service, see Supported Services.

Default metric charts use predefined service (Monitoring service) The expression to evaluate for returning aggregated data. A valid query includes a metric, statistic, and interval. In the Console, you can view a query in Basic Mode or Advanced Mode. The latter displays the Monitoring Query Language (MQL) syntax.. You can select The cloud objects that your company's employees create and use when interacting with Oracle Cloud Infrastructure. of interest and update the (Monitoring service) The time window used to convert the given set of raw data points. Example: 5 minutes, The aggregation function applied to the given set of raw data points. Example: SUM, and time range.

Note

Very small or large values are indicated by International System of Units (SI units), such as M for mega (10 to the sixth power). Units correspond to the selected metric and do not change by statistic.
