Functional Overview
Physical server and virtual server performance information from the Red Hat virtualization function (Xen) is collected and managed centrally.
The virtual server performance information collected by this function is put together with the physical server performance information and evaluated comprehensively. Accordingly, the resources in the server can be optimized, and improved user efficiency can be achieved.
The physical server performance information (physical server CPU, memory, and disk usage status) is displayed as a report.
The virtual server performance information (guest CPU, memory, and disk usage status) accumulates in guest units and is displayed as a report.
Information that can be collected
The methods used to collect the physical server and virtual server performance information and the main function information for the Red Hat virtualization function (Xen) are shown below.
Physical Server | Virtual Server |
|---|---|
CPU/memory/disk performance information is collected from the host operating system (Linux). | CPU/memory/disk performance information is collected from the host operating system (Linux). |
Note
If the Red Hat virtualization function (Xen) is a monitoring target, then Linux performance information will also be collected from the host operating system.
Point
The Red Hat virtualization function (Xen) can also be managed using Agentless Monitoring (refer to "3.2 Virtual Resource Managementt" for details).
Collection Interval
The collection interval is one minute.
Procedure
The linkage procedure is explained as follows:
