1. A method for detecting an occurrence of an event in a processor-based system, comprising:
- determining if a first pattern is stored in a log file;
determining if a second pattern is stored in the log file; and
indicating an occurrence of the event in the processor-based system in response to determining that the first pattern and the second pattern are stored in the log file within a preselected time of each other.

Abstract
The present invention provides a method and apparatus for identifying occurrences of selected events in a system. The method includes determining if a first pattern is stored in a log file, determining if a second pattern is stored in the log file and indicating an occurrence of the event in the processor-based system in response to determining that the first pattern and the second pattern are stored in the log file within a preselected time of each other.

10. An apparatus, comprising:
-
a storage unit; and
a control unit communicatively coupled to the storage unit, wherein the control unit is adapted to;
identify a first string in a file stored in the storage unit, wherein the first string is associated with an event;
identify a second string in the file, wherein the second string is associated with the event;
determine if the second string is stored in the file within a preselected time of the first string being stored in the file; and
provide an indication of an occurrence of the event in response to determining that the second string is stored within the preselected time of the first second string being stored. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An article comprising one or more machine-readable storage media containing instructions that when executed enable a processor to:
-
determine whether a sequence exists in a log file, where the sequence comprises at least a first pattern and a second pattern and is associated with an event; and
indicate that the event has occurred based on determining that the sequence exists in the log file. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. An apparatus for detecting an occurrence of an event in a processor-based system, comprising:
-
means for determining if a first pattern is stored in a log file;
means for determining if a second pattern is stored in the log file; and
means for indicating that the event occurred in the processor-based system in response to determining that the first pattern and the second pattern are stored in the log file within a preselected time of each other. - View Dependent Claims (26)

27. A method, comprising:
-
defining a first pattern of a sequence, wherein the first pattern has an associated life span;
defining a second pattern of the sequence; and
searching for the first pattern;
searching for the second pattern in response to locating the first pattern; and
indicating that the sequence was detected in response to determining that the second pattern occurred within the life span of the first pattern. - View Dependent Claims (28, 29)
