The code that builds the main NMS page has been updated. The update changes how status for groups of devices is reflected on the page. In the old code, the status indicator showed the status of device in that group that was in the worst condition. If even one device in the group was down, the group would show a red status. The new code takes into account the number of devices in a degraded condition relative to the total number of devices. The status indicators reflect the relative "badness" of the state of the group with a sequence of colors from green to red. The sequence, and what each color means, is shown below.

 GREEN
Green status - 100% of the devices in the group responded to all polling
 YELLOW GREEN
Strobing green/yellow status - All devices in the group are up, but one or more are in a degraded state *
 YELLOW
Yellow status - at least 1 and fewer than 1/3 of the devices in the group are down
 ORANGE
Orange status - 1/3 to 2/3 of the devices in the group are down

 RED
Red status - more than 2/3 of the devices in the group are down

 ERROR
Error status - indicates a failure in the polling scripts


* The code calls this status yellow green, however the color that is 50/50 green and yellow is not different enough from pure green to be readilly distinguished (see below). So, strobing green and yellow is used instead.
green
yellow-green
yellow

Devices in a degraded condition (those that respond to some polls, but not all) are not counted in the average that is used to determine the overall status indicator. Degraded devices are only evident when all devices in the group are up, but one or more is degraded. If even one device is down the status will fall at least to yellow without regard to the number of degraded devices.
