2. Monitoring Performance with Resource Monitor
Windows Home Server 2011 comes with a new tool for
monitoring your system: the Resource Monitor. You load this tool by
selecting Start, typing monitor, and then choosing Resource Monitor in the search results. Figure 6 shows the Resource Monitor window.
The Resource Monitor is divided into five tabs:
Overview—
This section shows a couple of basic metrics in four categories: CPU,
Disk, Network, and Memory, as well as graphs that show current activity
in each of these categories. To see more data about a category (as with
the CPU category in Figure 6), click the downward-pointing arrow on the right side of the category header.
CPU— This section (see Figure 7)
shows the CPU resources that your system is using. In two lists named
Processes and Services, you see for each item the current status (such
as Running), the number of threads used, the CPU percentage currently
being used, and the average CPU percentage. You also get graphs for
overall CPU usage, service CPU usage, and CPU usage by processor (or by
core).
Memory—
This tab displays a list of processes, and for each one it shows the
average number of hard memory faults per minute, the total memory
committed to the process, the working set (the number of kilobytes
resident in memory), the amount of shareable memory (memory that other
processes can use if needed), and the amount of private memory (memory
that is dedicated to the process and cannot be shared).
Tip
A memory fault does not refer to a physical problem.
Instead, it means that the system could not find the data it needed in
the file system cache. If it finds the data elsewhere in memory, it is
a soft fault; if the system has to go to the hard disk to retrieve the
data, it is a hard fault.
Disk—
This tab shows the total hard disk I/O transfer rate (disk reads and
writes in bytes per minute), as well as separate read and write
transfer rates.
Network— This tab shows the total network data-transfer rate (data sent and received in bytes per minute).
