You can view Availability Monitoring metrics to obtain a quick insight into the monitor's availability, the number of connections established, the number of DNS lookups, and so on.

The Availability Monitoring metrics are emitted as soon as the monitor is created and are displayed in charts on the <name of the monitor> page. These metrics are also available in the oracle_apm_synthetics namespace in the Metrics Explorer of the Oracle Cloud Infrastructure Monitoring service and can be used to build queries and create alarms. Note that to use the Monitoring service for Application Performance Monitoring, you must have the required Monitoring service permissions. For information, see Oracle Cloud Infrastructure Monitoring Service Permissions.

For a complete list and descriptions of Availability Monitoring metrics, see Available Metrics: oracle_apm_synthetics.

In Availability Monitoring, on the <name of the monitor> page, under Metrics, you can perform the following actions:

• Specify the time range for the metrics using the Start Time, End Time, and Quick Select fields.
• Specify the following for each metric:
  • Interval: The time window used to convert the given set of raw data points. For example, 5 minutes.
  • Statistic: The aggregation function applied to the given set of raw data points. For example, Sum.
• Select one of the following options from the Options menu on the top right of a metric chart to perform the following tasks:
  • View Query in Metrics Explorer: Click to monitor the query, which includes the metric, interval, and statistic in Metrics Explorer of the Monitoring service. You can use the Edit queries option in Metrics Explorer to edit query information.

    For information on viewing and building queries in Metrics Explorer, see Building Metric Queries.

  • Copy Chart URL: Click to copy the metric chart URL. This URL is to the metric chart in Metrics Explorer.
  • Copy Query (MQL): Click to copy the query 's Monitoring Query Language (MQL) expression. The query components appear in the following order in an MQL expression:

    metric[interval]{dimensionname="dimensionvalue"}.statistic

    For information on MQL expressions, see Monitoring Query Language (MQL) Reference.

  • Create an Alarm on this Query: Click to create an alarm for this query on the Alarm Definitions page of the Monitoring service. The alarm will then be triggered when the value of a metric is greater than the specified value, or is not optimal, or if the monitor is down.

    You can also view firing alarms for the Availability Monitoring metrics in the Alarms widget on the Application Performance Monitoring Home page.

    For information on creating alarms, see Managing Alarms.

  • Table View: Click to view the metric in a table format.
