View Patent ↗A non-transitory machine-readable storage medium is described in which discovery job instructions initiate a discovery job to discover target configuration items associated with a target business service in an information technology infrastructure. The storage medium comprises scoping instructions to, for a first configuration item and in response to a first stop condition not existing, designate the first configuration item as one of the target configuration items and continue the discovery job from the first configuration item to a second configuration item; and for the second configuration item and in response to the first stop condition or a second stop condition existing, stop the discovery job from proceeding from the second configuration item to a third configuration item.
1. A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the storage medium comprising instructions executable to:
initiate a discovery job in a directed graph stored in a configuration management database (CMDB) to discover configuration items associated with a target business service in an information technology infrastructure comprising a plurality of configuration items, the discovery job to apply one or more rules and corresponding stop conditions to determine whether discovered configuration items are associated with the target business service, wherein the directed graph is stored in the CMDB prior to initiation of the discovery job, the directed graph including the plurality of configuration items;
identify, by the discovery job in the CMDB, a first configuration item in the directed graph that is associated with the target business service in response to a first stop condition not existing;
identify, by the discovery job in the CMDB, a second configuration item in the directed graph that is a direct successor of the first configuration item after the identification of the first configuration item that is associated to the target business service;
after the identification of the second configuration item, determine, by the discovery job in the CMDB, whether the directed graph indicates that the second configuration item is internal to a boundary of the target business service associated with the first configuration item; and
in response to a determination that the directed graph does not indicate that the second configuration item is internal to the boundary of the target business service:
stop the discovery job from proceeding from the second configuration item to a third configuration item in the directed graph, and
disassociate the second configuration item from the target business service.
2. The non-transitory machine-readable storage medium of claim 1 , the instructions executable to:
for the second configuration item:

compare the number of hops to a hop index.
3. The non-transitory machine-readable storage medium of claim 2 :
the instructions executable to:
determine a shortest path of a plurality of paths from the second configuration item to the starting configuration item; and
in response to a determination that the shortest path has a number of hops that is less than or equal to the hop index, designate the second configuration item as being internal to the boundary of the target business service.
4. The non-transitory machine-readable storage medium of claim 3 , the instructions executable to:
in response to a determination that the second configuration item is internal to the boundary of the target business service:
associate the second configuration item with the target business service; and
continue the discovery job from the second configuration item to another configuration item.
5. The non-transitory machine-readable storage medium of claim 2 , the instructions executable to receive the hop index via user input.
6. The non-transitory machine-readable storage medium of claim 1 , wherein the second configuration item is associated with another business service that is different from the target business service.
7. The non-transitory machine-readable storage medium of claim 1 , the instructions executable to:
receive a border rule via user input; and
use the border rule to determine whether the directed graph indicates that the second configuration item is internal to the boundary of the target business service.
8. The non-transitory machine-readable storage medium of claim 1 , the instructions executable to:
receive a notification that a fourth configuration item has been disassociated from the target business service;
in response to the notification:
identify a related configuration item that is associated with the disassociated fourth configuration item; and
disassociate the related configuration item from the target business service.
9. The non-transitory machine-readable storage medium of claim 8 , the instructions executable to identify the related configuration item by determining that the related configuration item is not a direct successor of an upstream configuration item that is associated with the target business service.
10. A system, comprising:
a storage to store a configuration management database (CMDB) comprising a directed graph, the directed graph including a plurality of configuration items that comprise an information technology infrastructure; and
a processor to:
initiate a discovery job in the directed graph stored in the CMDB to discover configuration items associated with a target business service among a plurality of business services in the information technology infrastructure, the discovery job to apply one or more rules and corresponding stop conditions to determine whether discovered configuration items are associated with the target business service, wherein the directed graph is stored in the CMDB prior to initiation of the discovery job;
identify, by the discovery job in the CMDB, a first configuration item in the directed graph that is associated with the target business service in response to a first stop condition not existing;
identify, by the discovery job in the CMDB, a second configuration item of the plurality of configuration items that is a direct successor of the first configuration item after the identification of the first configuration item that is associated to the target business service;
after the identification of the second configuration item, determine, by the discovery job in the CMDB, whether the directed graph indicates that the second configuration item is internal to a boundary of the target business service associated with the first configuration item; and
in response to a determination that the directed graph does not indicate that the second configuration item is internal to the boundary of the target business service:
stop the discovery job from proceeding from the second configuration item to a third configuration item in the directed graph, and
disassociate the second configuration item from the target business service.
11. The system of claim 10 , the processor to:
determine a shortest path of a plurality of paths from the second configuration item to a starting configuration item; and
in response to a determination that the shortest path has a number of hops that is less than or equal to the hop index, designate the second configuration item as being internal to the boundary of the target business service, continue the discovery job from the second configuration item to the third configuration item.
12. The system of claim 10 , the processor to:
in response to a determination that the second configuration item is internal to the boundary of the target business service:
associate the second configuration item with the target business service; and
continue the discovery job from the second configuration item to another configuration item.
13. The system of claim 12 , the processor to:
receive a notification that the second configuration item has been disassociated from the target business service;
in response to the notification:
identify a related configuration item that is associated with the disassociated second configuration item; and
disassociate the related configuration item from the target business service.
14. The system of claim 10 , the processor to:
receive a border rule via user input; and
use the border rule to determine whether the directed graph indicates that the second configuration item is internal to the boundary of the target business service.
15. A method, comprising:
