11. The method of claim 8 , wherein the encoded representation of the knowledge source can be programmatically used to receive a condition confidence value representing a confidence that a particular condition exists, and use said condition confidence value to evaluate a confidence that the problem exists.
11. The method of claim 8 , wherein the encoded representation of the knowledge source can be programmatically used to receive a condition confidence value representing a confidence that a particular condition exists, and use said condition confidence value to evaluate a confidence that the problem exists. 24. The method of claim 11 , wherein generating the encoded representation of the knowledge source comprises: specifying significance values for the conditions; and storing the significance values in the encoded representation, such that the significance values can be programmatically used to decline to report the problem when (1) one or more of the conditions are found to be true, (2) the true conditions indicate that the problem is currently present in the deployment, and (3) a condition confidence value of at least one of the true conditions does not exceed the significance value of that particular condition.
