Formerly known as: Publish the metric or condition that caused a symptom to appear.
Marcelo's recall was to add an attribute to Syndrome that contains keywords such as ones from the signature attribute (or a GUID pointing to a keyword list). The keywords can be used for a faster initial filtering of Syndromes that may be related to the symptom. This should reduce the number of subsequent signature look ups and improve the overall search performance - the gain is greater when the signature of the Syndromes are more complex.

From Nov 12: An example might be the inclusion of a Syndrome keyword for the target platform, such as a Syndrome only relevant to z/OS. Authoring tools could make use of this keyword to list only Syndromes relevant to z/OS.
Question outstanding as to whether the current Syndrome "type" field could contain this information, ie: type=Security.access-violation.zOS
