Every object or link has got its state. In the system web interface all objects and links are highlighted with the corresponding color depending on their state.
Object states can change during the monitoring process depending on gotten data according to a set of predefined state change conditions.
The default set of states includes:
CREATED
WORKING
OVERLOADED
ALARM
NO DATA
DOWN
DISABLED
For example, an object of the class CPU has got the state WORKING if 1 minute average load is less than 80 %; otherwise the state changes to OVERLOADED. This behavior is predefined by default, it can be modified for the whole CPU class or a single object in the section State change conditions.
It is possible to set up correspondence between colors and states, and extend the default set of states in the section States list of the System configuration window.
