Monitoring ECSs

Monitoring is key for ensuring ECS performance, reliability, and availability. Using monitored data, you can determine ECS resource utilization. The cloud platform provides Cloud Eye to help you obtain the running statuses of your ECSs. You can use Cloud Eye to automatically monitor ECSs in real time and manage alarms and notifications to keep track of ECS performance metrics.

Server Monitoring includes Basic Monitoring and OS Monitoring.

Basic Monitoring automatically reports ECS metrics to Cloud Eye.
Using the agent installed on the target ECS, OS Monitoring provides system-wide, active, and fine-grained ECS monitoring.
For instructions about how to install and configure the agent, see Server Monitoring in Cloud Eye User Guide.

One-Click Monitoring

ECSs run on physical hosts. Although there are multiple mechanisms to ensure system reliability, fault tolerance, and high availability, host hardware might be damaged or power failures might occur. The cloud platform supports automatic recovery by default. If a physical host accommodating ECSs breaks down, the ECSs will automatically be migrated to a functional physical host to minimize the impact on your services. During the process, the ECSs will restart. For details, see Can ECSs Automatically Recover After the Physical Host Accommodating the ECSs Becomes Faulty?

You can enable one-click monitoring on the Cloud Eye console so that you will be notified if high availability occurs (if a physical host accommodating ECSs is faulty, the ECSs will automatically be migrated to a functional physical host). For details, see One-Click Monitoring.
