Introduction to Server Monitoring
Server monitoring includes basic monitoring, OS monitoring, and process monitoring.
- Basic monitoring automatically reports ECS or BMS metrics to Cloud Eye.
- OS monitoring provides server monitoring that is system-wide, active, and fine-grained after the Agent is installed on an ECS or a BMS.
- Process monitoring is used to monitor active processes on a host.
- Both Windows and Linux OSs are supported. For details, see What OSs Does the Agent Support?
- After the Agent is installed, data of Agent metrics is reported once every 1 minute.
- For the ECS specifications, you are advised to use 2 vCPUs and 4 GB of memory for Linux and 4 vCPUs and 8 GB of memory or higher specifications for Windows.
- The Agent will use the system ports. For details, see descriptions of ClientPort and PortNum in (Optional) Manually Configuring the Agent. If the Agent port is in conflict with a service port, see What Should I do If the Service Port Is Used by the Agent?
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.
To meet the basic monitoring and O&M requirements for servers, server monitoring monitors more than 40 metrics, such as those for CPU, memory, disk, and network.
The Agent's system resource usage is low. In an ECS or a BMS, the Agent uses less than 5% CPU and less than 100 MB memory.
