    Abstract: A method and apparatus for reliable I/O performance anomaly detection. In one embodiment of the method, input/output (I/O) performance data values are stored in memory. A first performance data value is calculated as a function of a first plurality of the I/O performance data values stored in the memory. A first value based on the first performance data value is calculated. An I/O performance data value is compared to the first value. A message is generated in response to comparing the I/O performance value to the first value.

    Abstract: Method and apparatus for detecting a hung up and/or slow-running syscall without affecting the performance of the syscall. Before a syscall is started, a time stamp can be created at a memory address that is distinct from memory addresses to be used by the syscall. While a syscall thread handles the syscall operation, a separate monitor thread monitors the time stamp to track the length of time the syscall operation has been running. If the syscall thread operation exceeds a threshold time limit, then a flag can be sent to a network administrator to indicate that the syscall may be hung up and/or slow running.

    Abstract: An embodiment of a method of writing data begins with a first step of generating a timestamp. A second step issues a query that includes the timestamp to each of a plurality of primary storage devices. The method continues with a third step of receiving a query reply from at least a quorum of the primary storage devices. The query replies indicate that the timestamp is later than an existing timestamp for the data. In a fourth step, the data is mirrored to secondary storage after receiving the query reply from at least the quorum of the primary storage devices. Upon receiving a mirror completion message from the secondary storage, a fifth step issues a write message that includes at least a portion of the data and the timestamp to each of the primary storage devices.

    Abstract: In certain embodiments, a method for modeling interactions with a computer system includes collecting interaction information for each of a number of interaction sessions with a computer system, each interaction session being associated with a corresponding agent system and including one or more states and one or more state transitions. The interaction information for an interaction session includes data for the one or more states and the one or more state transitions of the interaction session. The method further includes, for each of the interaction sessions, identifying the one or more states encountered during the interaction session based on the collected interaction information and generating, based on the one or more states encountered during the interaction session, a trace of the interaction session. The method further includes generating, based on the traces of the interaction sessions, a model of the interaction sessions, the model including the traces for each of the interaction sessions.
