Every Business Process requires an Operator. This operator defines its behaviour and specifies how its very own state is going to be calculated.
The AND operator selects the WORST state of its child nodes:
The OR operator selects the BEST state of its child nodes:
The XOR operator shows OK if only one of n children is OK at the same time. In all other cases the parent node is CRITICAL.
Useful for a service on n servers, only one of which may be running. If both were running,
race conditions and duplication of data could occur.
The DEGRADED operator behaves like an AND, but if the resulting
state is CRITICAL it transforms it into a WARNING.
Refer to the table below for the case-by-case
analysis of the statuses.
The MIN operator selects the WORST state out of the BEST n child node states:
