Abstract

A method is disclosed for collecting, aggregating and monitoring network management information from a plurality of network devices in a network management system. The method utilizes user-definable configuration information that contains an operational specification on what to collect, aggregate and monitor, which can be scheduled at desired times or intervals. The method begins by identifying network devices on the network, then querying and acquiring data in accordance with instructions contained in the operational specification. The method performs transformations and will periodically monitor the data for compliance with specific threshold conditions. Notifications are generated whenever a threshold condition has been met. Data is stored to a database and aggregated to generate trending information. Data stored in the database can be subsequently removed automatically based on aging or other criteria specified by the user. The method renders data to a display for viewing by the user using device-specific GUI attributes.

Claims

1. A method of collecting network management information from a plurality of network devices in a network management system, the method comprising the computer-implemented steps of:

configuring said network management system to acquire data from specific network devices from said plurality of network devices based on a user-definable operational specification;

querying said specific network devices for data to form a set of acquired data based on said operational specification;

transforming said acquired data to form a set of transformed data based on one or more formulas specified in said operational specification; and

storing said transformed data to an information base to form a set of stored data based on said operational specification.

2. A method as recited in claim 1, wherein said operational specification is defined in an Extensible Markup Language file.

3. A method as recited in claim 1, wherein said operational specification includes a scheduling block to direct said network management system to perform said querying step at a preset point in time.

4. A method as recited in claim 1, wherein the step of querying said specific network devices includes using a network communication protocol that is defined in said operational specification for each of said specific network devices.

5. A method as recited in claim 1, wherein the step of transforming said acquired data includes performing at least one arithmetic transformation on said acquired data, wherein said arithmetic transformation is specified by said operational specification.

6. A method as recited in claim 1, further comprising the step of monitoring said acquired data, said transformed data and said stored data for compliance with at least one threshold criterion value specified by said operational specification.

7. A method as recited in claim 6, further comprising the step of generating a notification when any of said acquired data, said transformed data and said stored data complies with said threshold criterion.

8. A method as recited in claim 1, further comprising the step of aggregating said stored data to form a set of trending data by performing at least one arithmetic aggregation on said stored data, wherein said arithmetic aggregation is specified by said operational specification.

9. A method as recited in claim 1, further comprising the step of removing a quantity of said stored data from said information base in accordance with information in said operational specification.

10. A method of collecting and aggregating network management information from a plurality of network devices in a network management system, the method comprising the computer-implemented steps of:
