Data transfers within and between nodes in a distributed computing environment are visualized. In one aspect, the nodes are represented as geometrical shapes. The first part of the geometrical shape represents logic of the corresponding node. The second part of the geometrical shape represents storage of the corresponding node. A line connecting the first part and the second part represents data transfer between logic of a node and storage of a node. Both inter-node and intra-node transfers may be shown.

Visualizing data transfers in distributed file system

Visualization used to show resource usage over time by different entities or jobs allows a user to see the resource usage of entities over time. Entities or jobs may be shown as horizontal bundles, possibly expanding or contracting within the constraints of the capacity of the system. Bundles can expand or contract but maintain continuity in a direction, for example, a horizontal continuity. The visualization or layout in one embodiment is updated not only for new incoming events, but also retroactively for past events, thus achieving smooth horizontal bundles as much as possible.

An embodiment of the invention provides a method of displaying a data flow, wherein a description of a data flow application to be displayed is received. The data flow application includes nodes and edges connecting the nodes, wherein the nodes represent operators and the edges represent data connections for data flowing between the operations. A reason that a user is to view the data flow and/or a user constraint on a complexity of the data flow application to be displayed is determined with a processor; and, the time required to render a display of the data flow application is estimated. A transformed representation of the data flow application is created with the processor. The transformed representation is created based upon the user reason, the user constraint, the estimated time of rendering, and/or a layout strategy. The transformed representation is displayed on a graphical user interface.

Improved techniques for flow analysis in messaging systems are disclosed. For example, a method for finding correlations between messages of a system based on content includes the following steps. For one or more executions of the system, obtaining the messages of the system, wherein each message has a schema associated therewith. The messages are categorized into groups, wherein each group has a common schema. Pairs of messages from disparate groups are found wherein, for the messages of a pair, there is a feature in common in their contents.

Methods and apparatus are provided for non-deterministic incremental program replay using checkpoints and syndrome tracking. Replay of a program proceeds by, for a given execution of the program, recording one or more checkpoints of the program, the one or more checkpoints containing program state information; and a recorded list of values for one or more identified variables executing in one or more threads of the program. Thereafter, during a replay execution of the program, the process continues by commencing execution from a particular one of the recorded checkpoints; restoring the program state information associated with the particular one of the recorded checkpoints; comparing an observed list of values to the recorded list of values for the one or more identified variables executing in each of the one or more threads; and identifying a difference between the observed list of values and the recorded list of values. A perturbation or suspend statement can optionally be introduced into the replay execution of the program.
