Critical observations (9)
These observations are considered critical in terms of data quality. An operator should aim to have zero critical observations in their data.

Advisory observations (1120)
These observations suggest there may be an error in the data. However, for some types of services these may be intended by the operator. Advisory observations should be investigated and addressed. If the observation is a result of intended behaviour, an operator can suppress the observation.
