Abstract

The disclosed architecture utilizes realtime continuous event processing (CEP) to address the use of a general input interface framework to import a dynamic set of event types (e.g., assets), and a declarative, expressive query model to implement monitoring and management tasks on an asset level. In one implementation, a realtime event processing system is provided, comprising a synchronization component configured to synchronize realtime event data and static event data of assets, and a realtime merge component configured to merge the synchronized realtime event data and static event data into a realtime event stream using one or more operators. The merged synchronized realtime event data and static event data is queriable as a single event type using a query to return related asset items.

Claims

1. A computing device, comprising:

a memory and a processor, wherein the memory and the processor are respectively configured to store and execute instructions, including instructions for causing the computing device to perform operations, the operations including;

synchronizing realtime event data regarding a selected plurality of assets and static event data regarding the selected plurality of assets, the synchronizing including obtaining the realtime event data for each of the selected plurality of assets, the realtime event data for each of the selected plurality of assets representing that asset at a specific point in time, and the specific point in time for each of the selected plurality of assets being a same point in time; and

merging the synchronized realtime event data regarding the selected plurality of assets and the static event data regarding the selected plurality of assets, using one or more operators, into a realtime event stream;

querying the realtime event stream as a single event type using a query; and

outputting multiple assets of the selected plurality of assets that match the query as output of the query.

2. The computing device of claim 1, wherein the outputted multiple asset items are obtained from a data source at least one of every predetermined number of time units, according to a predetermined time unit, or according to a latency threshold relative to a changed data source value.

3. The computing device of claim 1, wherein the query is a standing declarative query.

4. The computing device of claim 1, wherein the operations further comprise:

signaling a change in information related to an asset.

5. The computing device of claim 4, wherein the operations further comprise:

detecting a change in status of a static asset property of an associated data source related to membership of the static asset property in a group of asset properties being monitored using the query.

6. The computing device of claim 1, wherein the operations further comprise:

confirming actual values of the realtime event data are obtained for the same point in time for each individual asset.

7. The computing device of claim 1, wherein the one or more operators include a join operator configured to merge realtime event data and static event data of corresponding assets into a single composite realtime event stream, and a union operator configured to merge realtime event data and static event data of different assets of the same type into a realtime event stream.

8. The computing device of claim 1, wherein the query is formulated per asset.

9. A realtime event processing method, comprising acts of:

synchronizing realtime event data regarding a selected plurality of assets and static event data regarding the selected plurality of assets, the synchronizing including receiving the realtime event data for each of the selected plurality of assets, the realtime event data for each of the selected plurality of assets representing that asset at a specific point in time, and the specific point in time for each of the selected plurality of assets being a same point in time;

merging the synchronized realtime event data regarding the selected plurality of assets and static event data regarding the selected plurality of assets using one or more operators into a realtime event stream; and

querying the realtime event stream as the single event type to output a result stream of multiple related asset items, the realtime event stream queriable as a single event type.

10. The method of claim 9, further comprising detecting a change in status of a static asset property of an associated data source related to membership of the static asset property in a group of asset properties being monitored.

11. The method of claim 9, further comprising retrieving actual values of the realtime event data at the same point in time.

12. The method of claim 9, further comprising importing a specific set of event type properties into the query.

13. The method of claim 9, further comprising obtaining output of the query according to at least one of results from a data source issued at least every predetermined number of time units, results from a data source issued exactly according to a predetermined time unit, or results issued from a data source according to a latency threshold relative to a changed data source value.

14. The method of claim 9, further comprising merging synchronized realtime event data and static event data of different assets of the same type using an operator as a union of corresponding realtime and static event data into a single realtime event stream.

15. The method of claim 9, further comprising receiving the query as a declarative query over an asset as a single asset type that comprises a composite of the static and realtime asset properties.

16. A computer-readable storage device having computer-executable instructions stored therein that when executed by a processor cause a computing device to perform operations, the operations comprising:

synchronizing realtime event data associated with a selected plurality of assets and static event data associated with the selected plurality of assets, the synchronizing including obtaining the realtime event data for each of the selected plurality of assets for a same point in time;

merging the synchronized realtime event data and the static event data into a realtime event stream using one or more operators;

applying a query to the realtime event stream as the single event type, the realtime event stream queriable as a single event type; and

returning multiple related assets items as an output of the query.

17. The computer-readable storage device of claim 16, further comprising obtaining output of the query according to results from a data source issued at least every predetermined number of time units.

18. The computer-readable storage device of claim 16, further comprising obtaining output of the query according to results from a data source issued exactly according to a predetermined time unit.

19. The computer-readable storage device of claim 16, further comprising obtaining output of the query according to results from a data source issued according to a latency threshold relative to a changed data source value.

20. The computer-readable storage device of claim 16, wherein the query is a declarative query for the single asset type that comprises a composite of the static and realtime asset properties.
