Introduction to Server Monitoring
Server monitoring includes basic monitoring, OS monitoring, and process monitoring for servers.
- Basic monitoring includes metrics automatically reported by ECSs. The data is collected every 5 minutes. For details, see Services Interconnected with Cloud Eye.
- OS monitoring provides fine-grained OS monitoring for servers, and it requires the Agent to be installed on all servers that will be monitored. The data is collected every 1 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.
- Only Windows and Linux OSs are supported. For details, see What OSs Does the Agent Support?
- For the ECS specifications, you are advised to 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 OS, you must have the root permissions. For a Windows OS, 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 installed using public images provided by HUAWEI CLOUD. If any problem occurs when you use a private image, Cloud Eye will not provide technical support.
Monitoring Capabilities
Server monitoring provides more than 40 metrics, such as metrics for CPU, memory, disk, and network usage, meeting the basic monitoring and O&M requirements for servers.
Resource Usage
The Agent uses considerably less resources. When the Agent is installed on an ECS or BMS, it uses less than 5% of the CPU and less than 100 MB of memory.
