Overview

Oracle Cloud Infrastructure Database Migration metrics help you measure the amount of data replicated between source and target databases.

Note: Capacity of target databases can be monitored through the target database service and used to trigger alerts. For more information, see Use Autonomous Database Metrics to Monitor Databases and Use Enterprise Manager to Manage and Monitor Databases.

Terminology

The following terms are helpful for understanding metrics:

• Namespace: A container for Database Migration metrics. The namespace for Database Migration is oci_database_migration_service.

• Metrics: The fundamental concept in telemetry and monitoring. Metrics define a time-series set of datapoints. Each metric is uniquely defined by namespace, metric name, compartment identifier, a set of one or more dimensions, and a unit of measure. Each datapoint has a timestamp, a value, and a count associated with it.

• Dimensions: A key-value pair that defines the characteristics associated with the metric. For example, resourceId, which is the Database Migration deployment OCID.

• Statistics: Metric data aggregations over specified periods of time. Aggregations are done using the namespace, metric name, dimensions, and the datapoint unit of measure within the time period specified.

• Alarms: Used to automate operations monitoring and performance. An alarm keeps track of changes that occur over a specific period of time. It also performs one or more defined actions, based on the rules defined for the metric.
