Introduction to Server Monitoring
Server monitoring includes basic monitoring, process monitoring, and OS monitoring for servers.
- Basic monitoring covers metrics automatically reported by ECSs. The data is collected every 5 minutes. For details, see Services Interconnected with Cloud Eye.
- OS monitoring provides proactive and fine-grained OS monitoring for ECSs or BMSs, and it requires the Agent to be installed on all servers that will be monitored. The data is collected every minute. OS monitoring supports metrics such as CPU usage and memory usage (Linux). For details, see Services Interconnected with Cloud Eye.
- Process monitoring provides monitoring of active processes on hosts. By default, Cloud Eye collects CPU usage, memory usage, and number of opened files of active processes.
- Windows and Linux OSs are supported. For details, see What OSs Does the Agent Support?
- For the ECS specifications, use 2 vCPUs and 4 GB memory for a Linux ECS and 4 vCPUs and 8 GB memory or higher specifications for a Windows ECS.
- The Agent will use the system ports. For details, see descriptions of ClientPort and PortNum in (Optional) Manually Configuring the Agent (Linux). If the Agent port conflicts with a service port, see What Should I Do If the Service Port Is Used by the Agent?
- To install the Agent in a Linux server, you must have the root permissions. For a Windows server, you must have the administrator permissions.
Scenarios
Whether you are using ECSs or BMSs, you can use server monitoring to track various OS metrics, monitor server resource usage, and query monitoring data when faults occur.
Constraints
Server monitoring is available only for servers using public images provided by a cloud service platform. If any problem occurs when you use a private image, Cloud Eye will not provide technical support.
Monitoring Capabilities
Server monitoring provides multiple metrics, such as metrics for CPU, memory, disk, and network usage, meeting the basic monitoring and O&M requirements for servers. For details about metrics, see Services Interconnected with Cloud Eye.
Resource Usage
The Agent uses considerably less resources. When the Agent is installed on a server, it uses less than 5% of the CPU and less than 100 MB of memory.
