Overview

What Is Server Monitoring?

Monitoring is key for ensuring FlexusX instance performance, reliability, and availability. Using monitoring data, you can determine how well your FlexusX instance resources are being used. You can use Cloud Eye to track the statuses of your cloud servers. Cloud Eye automatically monitors cloud servers in real time and makes it easier to manage alarms and notifications, so that you can track cloud server performance metrics.

Server monitoring consists of basic monitoring, OS monitoring, and process monitoring.

Basic monitoring monitors metrics automatically reported by FlexusX instances, such as CPU usage.
OS monitoring provides proactive, fine-grained OS monitoring for FlexusX instances, and it requires the Agent to be installed on all FlexusX instances to be monitored.
Process monitoring monitors active processes on FlexusX instances, and it requires the Agent to be installed on the FlexusX instances to be monitored. By default, Cloud Eye collects CPU usage, memory usage, and the number of opened files of active processes.

Enabling Monitoring

On the FlexusX instance purchase page, you can choose whether to use Cloud Eye. Regardless of whether you use Cloud Eye or not, after the FlexusX instance is created, basic monitoring is provided for your instance by default. On the FlexusX instance purchase page:

If you select Cloud Eye, you will be able to view basic monitoring, OS monitoring, and process monitoring data on the FlexusX console. The OS monitoring and process monitoring data can be viewed only after the Agent is installed.
Figure 1 Selecting Cloud Eye
If you do not select Cloud Eye, you will only have the basic monitoring data provided on the FlexusX console.
If you want to view OS monitoring or process monitoring data, install the Agent, and then view the OS monitoring or process monitoring data on the Cloud Eye console.
