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

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.
