Systems and methods for discovering and monitoring devices using search patterns for object identifers and values
The present disclosure is directed to systems and methods of managing remote devices. The system can include a server with memory, a detection module, and a collection module. The memory can store a management information base (MIB) having a hierarchical tree of object identifiers and corresponding object values. The detection module can query devices and receive a first object identifier and its first object value, which can vary from those in the MIB; and use patterns to match the first object identifier and object value; and generate an identification of the device from the matches. The collection module can use the identification to select a collection template, which can indicate a subtree of the MIB and a collection pattern; traverse the subtree and identify a second object identifier that matches the collection pattern, and its second object value; and associate the second object value with the first object value.
1. A system for managing remote devices, comprising:
a memory that stores a management information base (MIB) having a hierarchical tree comprising a plurality of object identifiers and a plurality of corresponding object values;
a device comprising a second memory and one or more processors to:
receive a query for device information;
retrieve, from the second memory, an object identifier and an object value responsive to the query, the object identifier varying from each of the plurality of object identifiers stored in the MIB and the object value varying from each of the plurality of corresponding object values stored in the MIB; and
transmit the object identifier and the object value; and
a server comprising one or more second processors to:
receive, the transmitted object identifier and the object value from the device;
generate an identification of the device based on a first pattern that matches the object identifier and a second pattern that matches the object value;
select a collection template from a plurality of collection templates based on the identification of the device, the selected collection template indicating a subtree of the MIB and comprising a collection pattern accounting for variations between the first object identifier and each of the plurality of object identifiers of the MIB;
traverse, using the collection pattern template, the subtree of the MIB to identify a second object identifier that matches the collection pattern and a corresponding second object value; and
associate, in the memory, the corresponding second object value with the object value based on the collection pattern.
2. The system of claim 1 , wherein the memory stores, in the MIB, attributes associated with each of the plurality of object identifiers, the attributes comprising a data type, and a set of supported operations.
3. The system of claim 1 , wherein the object identifier varies from each of the plurality of object identifiers of the MIB.
4. The system of claim 1 , wherein the object value varies from each of the plurality of corresponding object values of the MIB.
5. The system of claim 1 , wherein the server detects that the object value varies from each of the plurality of corresponding object values of the MIB subsequent to production of the device.
6. The system of claim 1 , wherein the server implements a data collection strategy responsive to a variation between the object identifier and each of the plurality of object identifiers or the variation between the object value and each of the plurality of corresponding object values of the MIB.
7. The system of claim 1 , wherein at least one of the object identifier or the corresponding second object identifier comprise a numeric value or a string value.
8. The system of claim 1 , wherein the collection pattern comprises a regular expression that indicates a relationship between the corresponding second object value and the object value.
9. The system of claim 1 , wherein the server:
traverses the subtree using the collection pattern to identify each object identifier that matches the collection pattern; and
associates each object value corresponding to each object identifier that matches the collection pattern with the second object value in the memory.
10. The system of claim 1 , wherein at least one of the object identifier or the second object identifier is based on an X.690 object identifier.
11. A method for managing remote devices, comprising:
storing, by a memory, a management information base (MIB) having a hierarchical tree comprising a plurality of object identifiers and a plurality of corresponding object values;
receiving, by a device comprising a second memory and one or more processors, a query for device information;
retrieving, by the second device from the second memory, an object identifier and an object value responsive to the query, the object identifier varying from each of the plurality of object identifiers stored in the MIB and the object value varying from each of the plurality of corresponding object values stored in the MIB;
transmitting, by the second device, the object identifier and the object value;
receiving, by a server comprising one or more second processors, the object identifier and the object value from the device;
generating, by the server, an identification of the device based on a first pattern that matches the object identifier and a second pattern that matches the object value;
select a collection template from a plurality of collection templates based on the identification of the device, the selected collection template indicating a subtree of the MIB and comprising a collection pattern accounting for variations between the first object identifier and each of the plurality of object identifiers of the MIB;
traversing, by the server, using the collection pattern, a subtree of the MIB to identify a second object identifier that matches the collection pattern and a corresponding second object value; and
associating, by the server, in the memory, the corresponding second object value with the object value based on the collection pattern.
12. The method of claim 11 , further comprising storing, by the memory in the MIB, attributes associated with each of the plurality of object identifiers, the attributes comprising a data type, and a set of supported operations.
13. The method of claim 11 , wherein the object identifier varies from each of the plurality of object identifiers of the MIB.
14. The method of claim 11 , wherein the object value varies from each of the plurality of corresponding object values of the MIB.
15. The method of claim 11 , further comprising detecting, by the server, that the object value varies from each of the plurality of corresponding object values of the MIB subsequent to production of the device.
16. The method of claim 11 , further comprising implementing, by the server, a data collection strategy responsive to a variation between the object identifier and each of the plurality of object identifiers or the variation between the object value and each of the plurality of corresponding object values of the MIB.
17. The method of claim 11 , wherein at least one of the object identifier or the corresponding second object identifier comprise a numeric value or a string value.
18. The method of claim 11 , wherein the collection pattern comprises a regular expression that indicates a relationship between the corresponding second object value and the object value.
19. The method of claim 11 , further comprising:
traversing, by the server, the subtree using the collection pattern to identify each object identifier that matches the collection pattern; and
associating, by the server, each object value corresponding to each object identifier that matches the collection pattern with the second object value in the memory.
20. The method of claim 11 , wherein at least one of the object identifier or the second object identifier is based on an X.690 object identifier.
