A condition control that determines how metric-threshold
conditions are evaluated when data stops arriving.
This control doesn't affect metric-absence policies.
Values:
EVALUATION_MISSING_DATA_UNSPECIFIED (0):
An unspecified evaluation missing data option. Equivalent to
EVALUATION_MISSING_DATA_NO_OP.
EVALUATION_MISSING_DATA_INACTIVE (1):
If there is no data to evaluate the
condition, then evaluate the condition as false.
EVALUATION_MISSING_DATA_ACTIVE (2):
If there is no data to evaluate the
condition, then evaluate the condition as true.
EVALUATION_MISSING_DATA_NO_OP (3):
Do not evaluate the condition to any value if
there is no data.
