Overview
Monitoring is important to ensure FlexusL instance performance, reliability, and availability. You can use Cloud Eye to monitor FlexusL instances and know their statuses. Cloud Eye can monitor a range of metrics, such as the CPU usage, disk usage, and bandwidth of FlexusL instances.
How Do I Use Monitoring?
After you purchase a FlexusL instance, Cloud Eye is enabled by default. It can monitor the cloud servers, EVS disks, and CBR vaults packaged in the FlexusL instances.
For details, see Viewing Monitoring Metrics of a FlexusL Instance.
Cloud Server Monitoring
Server monitoring collects monitoring metrics at the OS layer of servers.
Server monitoring consists of basic monitoring, OS monitoring, and process monitoring. Basic monitoring does not require the Agent to be installed. OS monitoring and process monitoring require the Agent to be installed on the FlexusL instances to be monitored.
- Basic monitoring covers metrics automatically reported by FlexusL instances. The data is collected every 5 minutes. For details, see Table 2.
- OS monitoring provides proactive, fine-grained OS monitoring for FlexusL instances, and it requires the Agent to be installed on the FlexusL instances to be monitored. The data is collected every minute. In addition to the CPU usage, metrics such as memory usage can also be monitored. For details, see OS Monitoring Metrics.
- Process monitoring monitors active processes on FlexusL instances, and it requires the Agent to be installed on the FlexusL instances to be monitored. By default, Cloud Eye collects the CPU usage, memory usage, and the number of opened files of active processes.
EVS Monitoring
EVS monitoring collects metrics of EVS disks every 5 minutes on average. For details, see Viewing EVS Monitoring Data.
CBR Monitoring
CBR monitoring collects metrics of the used vault size and vault usage of CBR every 15 minutes.
