Health Matrix

The Health Matrix is a new and unique way to display the health of a large network, while at the same time using as little screen space as possible.

Health matrix using medium square size, displaying 68 computers while only requiring approximately 756 x 188 pixels

The overall health status of a monitored host is indicated by the color of its square / rectangle / circle (depending on your configuration). The health of a host is calculated using a point system. Any monitored item (e.g. service, disk space, performance counter) that is not within a valid range will accumulate a certain number of points (configurable). Only hosts with no (0) points will have a green status, whereas hosts with more than 1 point, but fewer than 3 (configurable) points will have an orange status. Hosts with more than 3 (configurable) points, will have a red status.

Color	Points	Description
Green	0	All monitored subsystems are in an OK state
Orange	more than 0, fewer than "Error Threshold" (3 by default)	A non-critical component is in an error state, or a critical component is in a warning state
Red	equal to, or more than "Error Threshold" (3 by default)	More than one non-critical components are in an error state, or a critical component is in an error state.

The number of points that are accumulated by a feature are configurable on a global (profile) basis, making it possible to weigh certain components more than others. To change the points generated by a section, simply click the "Edit" link of a category and adjust the points.

The Error Threshold can be adjusted by changing the corresponding value in the lower left corner and clicking "Update".

The Health Matrix page is refreshed every 5 minutes by default, and this interval can be adjusted by changing the "Refresh page every" value in the lower left corner of the page. The last refresh time is also shown below the refresh interval. Click the "Update" button whenever you make changes to the refresh interval or the error threshold.

By default, any computer that records either disk space or performance information, as well as hosts that are monitored by the heartbeat agent, are included in the health matrix. You can further narrow down the computers that are displayed by selecting one or more groups (all groups are displayed by default). A group is selected with a mouse click, multiple groups can be selected by holding the CTRL button while clicking group names.

The status of the following features is taken into consideration when calculating the overall health status of a host in the matrix:

Category	Feature	Points (default)
Heartbeat	Ping Status	3
	Agent Status	3
	TCP Status	1
Performance	Performance Counter #1 (CPU)	1
	Performance Counter #2 (System Memory)	1
	Performance Counter #3 (Disk Utilization)	1
Diskspace	All monitored fixed drives	1
Automatic Services	All services configured for automatic start	1

The current health status information is shown when you hover over a computer icon with the mouse. Simply click the computer icon to lock that information regardless of mouse movement. The computer details will now remain unchanged, even when you move the mouse over a different computer icon. You can click the computer icon again to unlock the computer details again.

Note that most items in the left pane are clickable if you need to obtain more information. For example, clicking on a drive letter will bring you the disk reports for that computer.

You can also disable entire categories by clearing the "Enabled" check box in the configuration dialog.

Both the icon / tile shape as well as size used for hosts are configurable. You can choose between a rectangle, square, a square with rounded edges and a circle. With the exception of the rectangle shape, all shapes are available in small, medium and large sizes.

The rectangle shape is the only shape which displays the host name within the icon. With all other shapes, the host name is retrieved by hovering over the icon with the mouse.

The icon shape and size can be changed using the controls on the lower left side of the screen. Please note this is a global settings, affecting all health matrix reports.
