Abstract

An analysis module is configured to receive data associated with an event flow. The data is received from a first analysis module (e.g., in a stack of analysis modules) or from the event flow. The analysis module is configured to execute an analysis operation on the data to generate a result. The analysis module can output the result to a second analysis module (e.g., in the stack of analysis modules) or to a user interface.

Claims

1. A system, comprising:

a processor; and

a memory coupled to the processor, the memory storing instructions, that when executed by the processor, cause the system to;

receive input indicating a selection of a plurality of analysis modules for incorporation into an ordered set of analysis modules configured for sequential operation on an associated event flow;

wherein a first analysis module of the selected plurality of analysis modules is operable for analyzing the event flow to obtain analysis data, the event flow including a plurality of events, each event including at least one of an operator, timing information or a payload, and

wherein a second analysis module of the selected plurality of analysis modules is operable for analyzing the analysis data output from the first analysis module.

2. The system of claim 1, wherein the input indicating the selection of the plurality of analysis modules for incorporation into the ordered set of analysis modules further comprises:

receiving input for reordering the plurality of analysis modules.

3. The system of claim 1, wherein the plurality of analysis modules comprises:

a replay analysis module configured to execute a replay analysis operation to simulate a passage of time based on one or more punctuation events.

4. The system of claim 3, wherein the replay analysis operation is further executable to:

show events at an analysis user interface (UI) having event lifetimes that include a particular point in the passage of time; and

hide events at the analysis UI having event lifetimes that do not include the particular point in the passage of time.

5. The system of claim 4, wherein the particular point in the passage of time is defined by user input.

6. The system of claim 1, wherein the plurality of analysis modules comprises:

a partition analysis module configured to execute a partitioning analysis operation.

7. The system of claim 1, wherein the plurality of analysis modules comprises:

an event propagation analysis module configured to execute an event propagation analysis operation with respect to a particular event to identify one or more subsequent events that are affected by the particular event.

8. The system of claim 1, wherein the plurality of analysis modules comprises:

a root cause analysis module configured to execute a root cause analysis operation with respect to a specific event to identify one or more previous events that affect the specific event.

9. The system of claim 1, wherein each of the plurality of analysis modules is independently executable with respect to other analysis modules.

10. The system of claim 1, wherein the input further indicates an ordering of the plurality of analysis modules and wherein each of the plurality of analysis modules is further configured to:

receive data from a previous analysis module based on the ordering; and

transmit data to a subsequent analysis module based on the ordering.

11. The system of claim 10, wherein the input for reordering the plurality of analysis modules comprises drag and drop input.

12. The system of claim 1, wherein the plurality of analysis modules comprises an analysis module configured to execute a filtering analysis operation to show those events at an analysis user interface that satisfy a filtering criteria, the filtering criteria including at least one of event type, event start time, event end time, event log time, event latency, event payload or a particular operator of a query.

13. The system of claim 1, wherein the plurality of analysis modules comprises at least two or more modules in a group of modules consisting of:

a replay analysis module configured to execute a replay analysis operation to simulate a passage of time based on one or more punctuation events,

a partition analysis module configured to execute a partitioning analysis operation,

an event propagation analysis module configured to execute an event propagation analysis operation with respect to a particular event to identify one or more subsequent events that are affected by the particular event, and

a root cause analysis module configured to execute a root cause analysis operation with respect to a specific event to identify one or more previous events that affect the specific event.

14. A system, comprising:

a processor; and

a memory coupled to the processor, the memory storing instructions, that when executed by the processor, cause the system to;

receive data representing an event flow, wherein the event flow is associated with a plurality of events, each event including at least one of an operator, timing information or a payload;

execute a first analysis module configured to;

execute a first analysis operation on at least a portion of the event flow to generate a first intermediate result and to output the first intermediate result to a subsequent analysis module; and

execute a second analysis module configured to;

receive the first intermediate result or a second intermediate result from a previous analysis module;

execute a second analysis operation on the first intermediate result or the second intermediate result to generate a final result, such that the final result is based at least in part on the first intermediate result obtained from the first analysis operation and such that the first and second analysis operations are part of an ordered set of analysis operations configured for sequential operations of analysis performed on the event flow; and

output the final result.

15. The system of claim 14, further comprising executing one or more additional analysis module after executing the first analysis module and before executing the second analysis module, wherein the one or more additional analysis module generates the second intermediate result from the first intermediate result, which is used by the second analysis module to execute the second analysis operation.

16. The system of claim 14, wherein the instructions are further configured, when executed by the processor, to receive input indicating a selection of the first and second analysis modules for incorporation into an ordered set of a plurality of analysis modules.

17. The system of claim 16, wherein each of the plurality of analysis modules is independently executable with respect to each other analysis module in the plurality of analysis modules.

18. The system of claim 16, wherein the input further indicates an ordering of the plurality of analysis modules and wherein each of the plurality of analysis modules is further configured to:

receive data from a previous analysis module based on the ordering; and

transmit data to a subsequent analysis module based on the ordering.

19. The system of claim 18, wherein the instructions are further configured, when executed by the processor, to:

receive reordering input for reordering the plurality of analysis modules; and
