Abstract

A method and system for monitoring and managing a network having at least one network manager resident within a network station and at least one network agent resident within a network device. The method and system accomplish their objects as follows. One or more network parameters of one or more network devices are grouped. In response to the grouping, a group monitor is constructed wherein any changes of the grouped one or more network parameters are reflected by the constructed group monitor. The constructed group monitor can thereafter be monitored for indications of changes in any of the grouped network parameters.

Claims

1. A method for monitoring and managing a network having at least one network manager resident within a network station and at least one network agent resident within a network device, the method comprising the steps of:

grouping interactively one or more network parameters of one or more network devices;

in response to the grouping step, automatically constructing a group monitor at the network agent wherein any changes of the grouped one or more network parameters are reflected by the constructed group monitor; and

monitoring the constructed group monitor instead of individual groups of network parameters for indications of changes in any of said grouped network parameters.

2. The method of claim 1, wherein the step of grouping further comprises the steps of:

selecting, on the basis of specific network management criteria, the one or more network parameters of one or more network devices; and

creating a group containing the selected one or more network parameters of one or more network devices.

3. The method of claim 2, wherein the step of constructing further comprises the steps of:

constructing a string, for a network device having one or more network parameters included within the created group, wherein unique regions within the constructed string identify one or more network parameters of the network device having one or more network parameters included within the created group; and

building a monitoring object containing the string constructed for a network device having one or more network parameters including within the created group.

4. The method of claim 3, wherein the step of constructing a string further comprises the step of associating a bit with each of the one or more network parameters including within the created group such that a change in the associated bit represents a change in a corresponding parameter of the network device.

5. The method of claim 3, wherein the step of monitoring further comprises the steps of:

querying the network agent as to the status of the built monitoring object;

in response to the query, examining the constructed string contained within the built monitoring object for an indication that one or more corresponding network parameters of interest of the device have changed; and

in response to an indication that one or more network parameters have changed, examining the changed network parameters such that network parameters of interest need only be examined when the parameters change.

6. A system for monitoring and managing a network having at least one network manager resident within a network station and at least one network agent resident within a network device, said system comprising:

means for grouping one or more network parameters of one or more network devices;

means, responsive to said means for grouping, for automatically constructing a group monitor at the network agent wherein any changes of said grouped one or more network parameters are reflected by said constructed group monitor; and

means for monitoring said constructed group monitor instead of individual groups of network parameters for indications of changes in any of said grouped network parameters.

7. The system of claim 6, wherein said means for grouping further comprises:

means for selecting, on the basis of specific network management criteria, said one or more network parameters of one or more network devices; and

means for creating a group containing said selected one or more network parameters of one or more network devices.

8. The system of claim 7, wherein said means for constructing further comprises:

means for constructing a string, for a network device having one or more network parameters included within said created group, wherein unique regions within said constructed string identify one or more network parameters of said network device having one or more network parameters included within said created group; and

means for building a monitoring object containing said strings constructed for a network device having one or more network parameters included within said created group.

9. The system of claim 8, wherein said means for constructing a string further comprises means for associating a bit with each of the one or more network parameters included within said created group such that a change in said associated bit represents a change in a corresponding parameter of said network device.

10. The system of claim 8, wherein said means for monitoring further comprises:

means for querying said network agent as to the status of said built monitoring object;

means, responsive to said query, for examining said constructed strings contained within said built monitoring object for an indication that one or more corresponding network parameters of interest of the device have changed; and

means, responsive to an indication that one or more network parameters have changed, for examining said changed network parameters such that network parameters of interest need only be examined when said parameters change.

11. A program product for monitoring and managing a network having at least one network manager resident within a network station and at least one network agent resident within a network device, said program product comprising:

program code for grouping one or more network parameters of one or more network devices;

program code responsive to said program code for grouping, for automatically constructing a group monitor at the network agent wherein any changes of said grouped one or more network parameters are reflected by said constructed group monitor;

program code for monitoring said constructed group monitor instead of individual groups of network parameters for indications of changes in any of said grouped network parameters; and

signal bearing media bearing said program code for grouping, said program code for constructing, and said program code for monitoring.

12. The program product of claim 11, wherein said signal bearing media further comprises transmission media.

13. The program product of claim 11, wherein said signal bearing media further comprises recordable media.

14. The program product of claim 11, wherein said program code for grouping further comprises:

program code for selecting, on the basis of specific network management criteria, said one or more network parameters of one or more network devices; and

program code for creating a group containing said selected one or more network parameters of one or more network devices.

15. The program product of claim 14, wherein said program code for constructing further comprises:

program code for constructing a string, for a network device having one or more network parameters included within said created group, wherein unique regions within said constructed string identify one or more network parameters of said network device having one or more network parameters included within said created group; and

program code for building a monitoring object containing said string constructed for a network device having one or more network parameters included within said created group.

16. The program product of claim 15, wherein said program code for constructing a string further comprises program code for associating a bit with each of the one or more network parameters included within said created group such that a change in said associated bit represents a change in a corresponding parameter of said network device.

17. The program product of claim 15, wherein said program code for monitoring further comprises:

program code for querying said network agent as to the status of said built monitoring object;

program code responsive to said query, for examining said constructed string contained within said built monitoring object for an indication that one or more corresponding network parameters of interest of the device have changed; and

program code, responsive to an indication that one or more network parameters have changed, for examining said changed network parameters such that network parameters of interest need only be examined when said parameters change.
