Which status code indicates a service check is in a CRITICAL state?

The status code that indicates a service check is in a CRITICAL state is the code that corresponds to a value of 2. In Datadog, different numerical codes are assigned to service check states to represent various conditions. Specifically, a CRITICAL state signifies that an essential service or component is not performing as expected and requires immediate attention.

For clarity, the other status codes are utilized for different states of service checks. A value of 0 typically indicates an OK state, showing that everything is functioning correctly. A value of 1 indicates a WARNING state, suggesting that there may be potential issues that could lead to a CRITICAL state if not addressed. The value 3 is associated with an UNKNOWN state, where the service check is unable to determine the status for some reason. Understanding the significance of each of these codes is essential for effectively monitoring and responding to system health in Datadog.
