Monitoring Metrics Supported by DataArts DataService
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 an exclusive cluster and enable Cloud Eye monitoring, Cloud Eye automatically associates with the exclusive cluster metrics to help you obtain the performance metrics of the exclusive cluster in real time and accurately monitor its running status.
- This section describes the exclusive cluster metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions.
- If you want Cloud Eye to monitor an exclusive cluster, enable Cloud Eye monitoring first. For details, see Enabling Cloud Eye Monitoring.
- For details about exclusive cluster monitoring metrics, see Viewing Monitoring Metrics of DataArts DataService.
- For details about how to set alarm rules, see Creating an Alarm Rule for DataArts DataService.
Prerequisites
You have obtained required Cloud Eye permissions.
