Abstract
Methods and systems to narrow a search for potential sources of problems in a distributed computing system are described. A volatile event type of event messages recorded in an event-log file is identified. The volatile event type is an event type that may have unexpectedly increased in frequency over an observation time window. An historical period of time may be selected to search for potential sources of the volatile event type. Frequencies of event messages in the event-log file with the same event type as the volatile event type are determined for time intervals of the historical period of time. A time interval of the historical period of time with a largest increase in frequency of event messages is identified. A list of event messages of the event-log file in a selected sub-time interval of the sub-time intervals of the time interval are displayed in a graphical user interface.
