Abstract

A cluster configuration system arranged to manage a graph database for tracking and identifying a time-varying state of a cluster of objects. The graph database may include one or more nodes and one or more associations between the nodes to represent time-varying states of the cluster. Management of the graph database may include creating, maintaining, updating, storing, administrating, querying, and/or presenting one or more elements of the graph database.

First claim

1 . An apparatus, comprising:
logic, at least a portion of which is implemented in hardware, the logic comprising an event correlation application to maintain a graph database of nodes and associations regarding configurations of a cluster of one or more objects, the event correlation application comprising:
a notification interface component to receive a notification, the notification to indicate a current configuration of one or more objects in the cluster;
an indexing component to compare the current configuration of the cluster with a previous configuration of the cluster, wherein the previous configuration of the cluster is associated with a previous timestamp node in the graph database; and
a graph engine to create a current timestamp node based on the received notification and associate the current timestamp node with the previous timestamp node in the graph-database based on the comparison of the current and previous configurations of the cluster.

2 . The apparatus of claim 1 , the indexing component to identify a configuration change between the previous configuration and the current configuration of the cluster based on the comparison of the current configuration to the previous configuration of the cluster.

3 . The apparatus of claim 2 , the configuration change comprising an object present in the previous configuration of the cluster and absent from the current configuration of the cluster.

4 . The apparatus of claim 2 , the configuration change comprising an object present in the current configuration of the cluster and absent from the previous configuration of the cluster.

5 . The apparatus of claim 4 , the graph engine to create a current object node to represent the configuration change in the representational database and associate the current object node with the current timestamp node in the representational database.

6 . The apparatus of claim 5 , the current object node comprising one or more properties of the object present in the current configuration of the cluster and absent from the previous configuration of the cluster.

7 . The apparatus of claim 1 , wherein the previous configuration of the cluster is associated with a previous object node in the graph database, the previous object node to represent a configuration of an object in the cluster at a previous moment in time.

8 . The apparatus of claim 7 , the graph engine to associate the current timestamp node with the previous object node in the graph database.

9 . The apparatus of claim 8 , wherein the configuration of the object represented by the previous object node remains unchanged between the previous configuration of the cluster and the current configuration of the cluster.

10 . The apparatus of claim 1 , the graph database comprising one or more hierarchical time trees (HTTs).

11 . The apparatus of claim 2 , the configuration change comprising property change in an object present in both the current configuration and previous configuration.

12 . The apparatus of claim 2 , the configuration change comprising of a relationship present in the previous configuration of the cluster but absent from the current configuration of the cluster.

13 . The apparatus of claim 2 , the configuration change comprising of a relationship present in the current configuration of the cluster but absent from the previous configuration of the cluster

14 . The apparatus of claim 2 , the configuration change comprising a property change in a relationship present in the current configuration and the previous configuration.

15 . A computer-implemented method, comprising:
receiving a request for a configuration of a cluster of one or more objects; identifying and/or creating a hierarchical time tree (HTT) of nodes and associations in a graph database based on the request, the HTT including a timestamp node, an object node, and an association between the timestamp node and the object node; and displaying data related to the requested configuration of the cluster in a graphical user interface (GUI) based on the identified HTT of nodes and associations.

16 . The computer-implemented method of claim 11 , the request for the configuration of the cluster including a moment in time or a relationship between configurations.

17 . The computer-implemented method of claim 12 , the data displayed including a set of object nodes representing the configuration of the cluster at the moment in time.

18 . The computer-implemented method of claim 13 , comprising adjusting the moment in time for which configuration data is displayed based on input received via the client interface component.

19 . The computer-implemented method of claim 11 , the request for the configuration of the cluster including a period of time.

20 . The computer-implemented method of claim 15 , the data displayed comprising a timeline for the configuration of the cluster over the period of time.

21 . One or more computer-readable media to store instructions that when executed by a processor circuit causes the processor circuit to:
receive a notification indicating a current configuration of a cluster of one or more objects; compare the current configuration of the cluster with a previous configuration of the cluster, the previous configuration of the cluster associated with a previous timestamp node in a graph database of nodes and associations; create a current timestamp node in the graph database based on the received notification; and associate the current timestamp node with the previous timestamp node in the graph database based on the comparison of the current and previous configurations of the cluster

22 . The one or more computer-readable media of claim 17 , with instructions to identify a configuration change between the previous configuration and the current configuration of the cluster based on the comparison of the current configuration to the previous configuration of the cluster.

23 . The one or more computer-readable media of claim 18 , the configuration change comprising an object or relationship present in the previous configuration of the cluster and absent from the current configuration of the cluster.

24 . The one or more computer-readable media of claim 18 , the configuration change comprising an object present in the current configuration of the cluster and absent from the previous configuration of the cluster.
