Supported Monitoring Metrics

Function

Cloud Eye monitors the running status of cloud services and usage of each metric, and creates alarm rules for monitoring metrics.

After you create a real-time processing migration job, Cloud Eye automatically associates monitoring metrics of the job. This helps you learn how the job performs in real time.

This section describes the metrics of real-time processing migration jobs that can be monitored by Cloud Eye as well as their namespaces and dimensions.
To view the monitoring metrics of real-time processing migration jobs, see Viewing Monitoring Metrics of a Real-Time Processing Migration Job.
For details about how to set alarm rules, see Setting an Alarm Rule for a Real-Time Processing Migration Job.

Prerequisites

To monitor real-time processing migration jobs, you must obtain Cloud Eye permissions.
