Systems and techniques are described for performing automatic problem diagnosis. Telemetry data of a system can be analyzed to identify a set of time ranges during which the telemetry data exhibits anomalous behavior. Next, a subset of log entries having a timestamp that is in one of the time ranges in set of time ranges can be extracted from a set of log entries generated by the system. The subset of log entries can then be analyzed, by using natural language processing, to identify a subset of the subset of log entries that has a high likelihood to be associated with one or problems in the system. Next, human-readable text can be extracted from the subset of the subset of log entries. A knowledge database can then be searched by using the human-readable text to identify one or more solutions to resolve the one or more problems in the system.
