The state of each domain.

The number of domains on the host.

Memory statistics of the host, such as the total available memory, the memory in use, and free memory.

The CPU statistics of the host, such as the number of CPUs and CPU speed.

Information on each domain, such as domain name, domain state, CPU usage in seconds, percentage of CPU, memory in Kilobytes, and so on.

For example, an xm top command displays output similar to:

Note that the format of each line of output wraps over two lines.

5.2.2 Viewing Host Information

Use the xm info, xm log, and xm dmesg commands to display information about the host computer. For example, the xm info command displays output similar to the following:
