Abstract

A performance management tool is provided that monitors performance in a computing infrastructure in a computing environment. The performance management tool includes a service model that represents the computing infrastructure. The service model is a hierarchical tree structure comprised of a plurality of linked nodes, where each node in the tree structure represents a component of the computing infrastructure and has one or more properties of the component assigned thereto. Each node further includes an inheritance rule which defines how properties assigned to other nodes are inherited by the component. A dimension indexer module is configured to receive a request for properties associated with a particular node and operates to retrieve properties for the particular node from the tree structure, including at least one property not assigned to the particular node but inherited from another node in the tree structure in accordance with the inheritance rule assigned the particular node.

a service manager embodied as computer executable instructions executed by a computer processor and includes

a container module configured to receive a request to assign a given property to a given node in the tree structure and operable, in response to the request to update, to assign the given property to the given node in the tree structure; and

a dimension indexer module configured to receive a request for properties associated with a particular node and operable, in response to the request for properties, to retrieve properties for the particular node from the tree structure, including at least one property not assigned to the particular node but inherited from another node in the tree structure in accordance with the inheritance rule assigned the particular node.

2. The performance management tool of claim 1 wherein each node in the tree structure includes at least one type of relationship with each parent node and an inheritance rule for each type of relationship assigned to the node.

3. The performance management tool of claim 2 wherein the particular node has a component relationship with its parent node when the component represented by the particular node is a subcomponent of the component represented by the parent node.

4. The performance management tool of claim 2 wherein the particular node has a dependency relationship with its parent node when the component represented by the particular node is dependent on the component represented by the parent node.

5. The performance management tool of claim 2 wherein the particular node has a value expression relationship with its parent node when the values expressed in the parent node are derived from values of properties assigned to the particular node.

6. The performance management tool of claim 2 wherein the particular node has a user count relationship with its parent node when the amount of users which access the component represented by the parent node applied to the component represented by the parent node.

7. The performance management tool of claim 2 wherein the dimension indexer module is operable to traverse ancestral nodes of the particular node to retrieve properties associated with the particular node.

8. The performance management tool of claim 1 wherein the dimension indexer is configured to receive a request to nodes in the tree structure having a particular property and operable, in response to the request, to retrieve a listing of nodes having the particular property, including at least one node in the listing of nodes is identified using an inheritance rule.

9. The performance management tool of claim 1 wherein the component is further defined as at least one a software service or a device in the computing infrastructure.

10. A method for monitoring performance of a computing infrastructure of an enterprise, the method comprising:

a) maintaining, at a processing device of a computing device, a service model representing the computing infrastructure, the service model being a hierarchical tree structure comprised of a plurality of nodes, each node representing a component of the computing infrastructure and being of a type of a plurality of types, each type of node representing a different type of component, wherein one or more dimensions are explicitly defined within each node, each of the one or more dimensions defining a property of the component represented by the node in which the dimension is explicitly defined;

b) receiving, at the processing device, a request to determine a set of dimensions pertaining to a particular type of node in the computing infrastructure;

c) identifying, at the processing device, a set of nodes in the service model that are of the particular type;

d) adding, at the processing device, the set of nodes to a list of nodes;

e) merging, at the processing device, the dimensions explicitly defined in a given node with the set of dimensions;

f) identifying, at the processing device, any parent nodes of the given node from which the given node is configured to inherit dimensions from based on an inheritance rule;

g) adding, at the processing device, the identified parent nodes to the list of nodes; and

h) repeating, at the processing device, operations e-g for each node in the list of nodes.

11. The method of claim 10, wherein the components are each one of a service of the computing infrastructure and a device in the computing infrastructure.

12. The method of claim 10, wherein each child node in the tree structure includes at least one inheritance rule defined therein, wherein each child node has one or more parent nodes and each inheritance rule of each child node defines whether the particular node inherits dimensions pertaining to its one or more parent nodes.

14. The method of claim 12, wherein each child node has a relationship with each of its one or more parents defined by a relationship type.

15. The method of claim 14, wherein each inheritance rule defined in each child node indicates whether the child node inherits dimensions from its parent nodes having a particular relationship type with the child node.

16. The method of claim 10, wherein when the particular node inherits the dimensions pertaining to the one or more ancestral nodes, the dimensions pertaining to the one or more ancestral nodes are attributed to the particular node without being explicitly defined in the particular node.

17. The method of claim 10, wherein merging the dimensions explicitly defined in the given node with the set of dimensions includes, for each of the dimensions explicitly defined in the given node, adding the dimension to the set of dimensions only when the set of dimensions does not include a previously merged dimension which defines a same property as the dimension to be merged.

18. The method of claim 10, further comprising providing the set of dimensions for display to a user after operations e-g have been performed for each node in the list of nodes.

19. The method of claim 10, further comprising storing the set of dimensions in a cache after operations e-g have been performed for each node in the list of nodes, wherein when a subsequent request for the set of dimensions pertaining to the particular type of node is received, the set of dimensions is retrieved from the cache.

13. The method of claiml2, wherein a root node of the plurality of nodes does not inherit dimensions from any other nodes in the tree structure, wherein the root node does not have any parent nodes.

20. A method for monitoring performance of a computing infrastructure of an enterprise, the method comprising:

a) identifying, at the processing device, every descendant node of the identified node which does not have the particular dimension explicitly defined therein and is configured to inherit the particular dimension from the identified node;

b) adding, at the processing device, each identified descendant node to the set of nodes.
