Group Status

Any group may optionally have a status that is dynamically calculated as a function of group members' state. The status is indicated as group's node color in the System Tree.

For example, a group of Devices is red if at least one device has error, yellow if at least one device is offline, and green otherwise.

Group Status Calculation

The group status is calculated according to the following rules.

1.	Every time when a new member is added or existing member's Member Status Variable is changed, the Member Status Expression is calculated for this member, resulting to member status string.

2.	All members status strings are then looked up in the Status Table, from top to bottom.

3.	The group status is set according to the highest Status Table record those Member Status Expression Result match at least one member's status string.

Let's assume that we have a group with five members. Every member's expression is evaluated into a string value that is normally 100, 200, 300, 400 or 500 (these are strings constants, not numbers). Here is our Status Table:

Member Status Expression Result	Group Status (Color)
100	Green
200	Yellow
300	Red
400	Magenta
500	Blue

The below table illustrates what status will the group get in accordance with different member status string combinations and the above table:

Member Status Strings	Group Status (Color)
100, 200, 300, 400, 500	Green
500, 400, 300, 200, 100	Green
300, 300, 300, 400, 500	Red
500, 500, 500, 500, 500	Blue
500, 500, 200, 500, 500	Yellow
200, 200, 500, 200, 200	Yellow
100, 200, 300, 400, 123	Undefined
