16. A method of diagnosing computing system performance, comprising: receiving operational data from a computing system; identifying an operational pattern based on the received operational data, the operational pattern including a temporal sequence of operations, events, or system states of the computing system; determining whether the identified operational pattern violates a reference operational pattern associated with an annotation identifying a reason, a cause, or a corrective suggestion corresponding to a violation of the temporal sequence; and in response to determining that the identified operational pattern violates a reference operational pattern, outputting, via a device remote from the computing system, the reason, cause, or corrective suggestion contained in the annotation for diagnosing performance of the computing system.

The method of claim 16 wherein: receiving the operational data includes receiving event logs from the computing system operating; and identifying the operational pattern includes: parsing the event logs based on keywords; identifying a temporal sequence of events based on the parsed event logs; and identifying a time interval between a pair of the events of the temporal sequence.
