1.2 Features of PFM - RM for Virtual Machine

PFM - RM for Virtual Machine is a program that monitors the performance of a virtual environment, and collects and manages its performance data.

This subsection describes the features of PFM - RM for Virtual Machine.

• Analysis of the operation status of a virtual environment

  PFM - RM for Virtual Machine collects and summarizes performance data, such as CPU usage and memory usage, from the monitored virtual environment, enabling the user to easily analyze the operation status of the virtual environment by graphically displaying its trends and history.

  A single instance of PFM - RM for Virtual Machine can monitor multiple virtual environments.

• Early detection of operational problems in a virtual environment and reporting of troubleshooting information

  When a problem such as a resource shortage occurs in the monitored virtual environment, PFM - RM for Virtual Machine can quickly alert the user via e-mail, thus ensuring early problem detection. Furthermore, by graphically displaying the information related to the problem, PFM - RM for Virtual Machine provides the necessary troubleshooting data.

To use PFM - RM for Virtual Machine, you need PFM - Manager, PFM - Base, and PFM - Web Console. However, PFM - Base is not necessary if you install both PFM - Manager and PFM - RM for Virtual Machine on the same host.

Note

In addition to PFM - RM for Virtual Machine, PFM - RM for Platform is a Performance Management product that can analyze the operation status of multiple hosts. Like PFM - RM for Virtual Machine, PFM - RM for Platform need not be installed on the host to be monitored. However, the types of performance data that PFM - RM for Platform can collect differ from those that can be collected by PFM - RM for Virtual Machine.
