Cloud Eye is a comprehensive monitoring platform for resources such as the ECS and bandwidth. You can use Cloud Eye to monitor the utilization of service resources, track the operating statuses of cloud services, configure alarm rules and notifications, and respond to resource changes.
You do not need to subscribe to the Cloud Eye service. Monitoring starts automatically after ECSs or scaling groups are created. After deploying a cloud service, you can view the service operating status and set alarm rules on the Cloud Eye console. For more information about automatic monitoring, see the "Querying ECS Basic Metrics" and "Querying Metrics of Other Cloud Services" sections in the Cloud Eye User Guide.
After installing the Agent (Telescope) on the ECS, you can collect 10-second level ECS monitoring data in real-time. Multiple metrics are supported, including the CPU, memory, and storage space usage. For more information about proactive ECS monitoring, see the "ECS Monitoring" section in the Cloud Eye User Guide.
You can create alarm rules for multiple DB instances at a time. After an alarm rule is created, you can flexibly manage it. For example at any time you can modify, enable, disable, or delete it. For more information about alarm rules, see the "Alarm Rule Management" section in the Cloud Eye User Guide.
You can subscribe to the Simple Message Notification (SMN) service when creating alarm rules. When monitoring metric data reaches the threshold specified in an alarm rule, Cloud Eye will send you notifications of cloud resource status changes in real time. These notifications can be SMS messages, emails, or messages to server addresses.
The monitoring panel enables you to view monitoring metrics of multiple services from multiple dimensions. It shows an overview and details of monitoring metrics, which helps you troubleshoot problems. For more information about the monitoring panel, see the "Using Monitoring Panel to Get a Cloud Service Running Panorama" section in the Cloud Eye User Guide.
If you subscribe to the Cloud Trace Service (CTS) service, you can view historical alarms from the last three days. If you subscribe to the SMN service, you can receive historical alarms through emails or SMS messages.
Raw data of each monitoring metric is kept for two days on Cloud Eye and then deleted. For a longer retention period, you can subscribe to the OBS service and save the raw data in it.
