Resource Monitor Overview
Windows Resource Monitor includes the following elements and features.
Resource Monitor includes five tabs: Overview, CPU, Memory, Disk, and Network. The Overview tab displays basic system resource usage information; the other tabs display information about each specific resource.
- Switch between tabs by clicking on the tab
- If you have filtered results on one tab, only
resources used by the selected processes or services will be
displayed on the other tabs. Filtered results are denoted by an
orange bar below the title bar of each table. To stop filtering
results while viewing the current tab, in the key table, clear the
check box next to Image.
Each tab in Resource Monitor includes multiple tables that provide detailed information about the resource featured on that tab.
- To expand or collapse a table, click the
arrow on the right side of the title bar of the table. Not all
tables are expanded by default.
- To add or hide data columns in a table,
right-click any column label, and then click Select Columns.
Select or clear the check boxes for the columns you want displayed.
Not all columns are displayed by default.
- The first table displayed is always the key
table, and it always contains a complete list of processes using
the resource included on that tab. (The key table on the
Overview tab contains a complete list of processes running
on the system.)
- To sort table data, click the label of the
column you want to sort by. To reverse the sort order, click the
column label again.
- You can filter the detailed data in tables
other than the key table by one or more processes or services. To
filter, in the key table, select the check box next to each process
or service you want to highlight. To stop filtering for a single
process or service, clear its check box. To stop filtering
altogether, in the key table, clear the check box next to
- If you have filtered results, tables other
than the key table will only display data for the selected
processes or services.
- To view definitions of data displayed in the
tables, move the mouse pointer over the column title you want more
- A process that is no longer running, but that
is included in the current displayed data, will appear as a gray
entry in a table until the data expires.
Each tab in Resource Monitor includes a chart pane on the right side of the window that displays graphs of the resources included on that tab.
- You can change the size of the graphs by
clicking the Views button and selecting a different graph
- You can hide the chart pane by clicking the
arrow at the top of the pane.
- If you have filtered results, the resources
used by the selected processes or services will be shown in the
graphs as an orange line.
- If you have multiple logical processors, you
can choose which ones are displayed in the chart pane. On the
CPU tab, click Monitor, and then click Select
Processors. In the Select Processors dialog box, clear
the All CPUs check box, and then select the check boxes for
the logical processors you want to display.
Resource Monitor displays one graph for each logical processor. For example, a computer with a single processor that has two cores will have two processor graphs in the chart pane on the CPU tab. For computers with multiple processors organized into NUMA nodes, you can use the Select NUMA nodes menu option to configure Resource Monitor to display all of the logical processors in a selected NUMA node.
