• How to collect data, generate graphs and report for virtual server memory usage by using Monitoring menu?ECL2.0, Monitoring, Virtual Server

  For virtual server memory usage (and others that are not included in the meters provided as standard in Monitoring menu), you can use Monitoring function (graph display, alert setting, etc.) by using Custom Meter.

  There are two methods to use Custom Meter. You can choose either or both of them according to your environment.

  1. Use a custom meter agent
  (Note: Windows OS is not included in the target operating system)

  2. Create and use a script (for collecting data and sending it to the monitoring server)
  (Note: The script needs to be prepared by customers)

  Please refer to the tutorial below for detailed procedure on each method.

• On Monitoring Control Panel, CPU utilization of Virtual Server Instance sometimes exceed 100%. Is this normal?ECL2.0, Monitoring, Virtual Server

  Yes. The maximum value is “100 percent x number of CPU cores”. (Example: If the virtual server instance is 16 CPUs, the value ranges from 0 to 1600 percent.)
  So CPU Utilization may exceed 100%, depending on the flavor of the virtual server.

• There is a difference between the value obtained by Monitoring and the value checked on the guest OS for the CPU usage rate of the virtual server.ECL2.0, Monitoring

  The data of the virtual server displayed on Monitoring service is acquired from the hypervisor housing the virtual server and this information includes not only the load of the guest OS but also overhead load due to virtualization.
  Therefore, the CPU usage rate displayed on Monitoring service may be different from the CPU usage rate displayed on the guest OS.

• Is there a ping monitoring function for virtual servers in Monitoring menu?ECL2.0, Monitoring

  No. Ping monitoring for virtual severs is not provided in Monitoring menu.
  As an alternative function, "Hypervisor Status" function is provided.

  For example, “VM dead peer monitoring” shows the monitoring result from the infrastructure side that provides the virtual server instance, and the trouble caused by internal instance problems (kernel panic or OS crash) occurring while the virtual server instance is running can not be detected.
  * If you want to do it by Ping, you need to do it yourself.

  For details, please refer the Service Descriptions.
