Abstract

An automation engine is configured to automatically run network data collection, analysis, and reporting tools. Each tool is designed or modified to enable the parameters required for operating the tool to be read from a settings file. The automation engine is configured to provide the appropriate settings file to each tool to perform a given set of tasks. Tasks can be performed on-demand, on predefined schedules, or upon detection of a triggering event.

Claims

1. A network monitoring system comprising:

at least two of the following three applications;

one or more data collectors,

one or more data analyzers,

one or more data reporters;

one or more task definitions, and

an automation engine that is configured to control the at least two components to effect a target task based on the one or more task definitions.

2. The network monitoring system of claim 1, wherein

the automation engine is configured to effect the target task based upon an occurrence of an event,

the event including at least one of:

a user-induced event,

a timed event,

an anticipated event,

an anomalous event, and

an alarm event.

3. The network monitoring system of claim 1, wherein

each of the at least two applications is configured to selectively receive input from either a user-interface or a stored set of inputs that provides parameters that define operational characteristics of the application to perform the target task.

4. The network monitoring system of claim 3, wherein

the stored set of inputs includes settings that provide the parameters, independent of the user-interface.

5. The network monitoring system of claim 4, wherein

the settings are stored values of the parameters that were determined after receiving the input from the user-interface.

6. The network monitoring system of claim 4, wherein

the settings correspond to the parameters of the application that are stored in an internal data-structure of the application to facilitate control of processes within the application to perform the target task.

7. The network monitoring system of claim 3, wherein

the stored set of inputs are stored in a collection of setting files, and

the automation engine is configured to selectively provide a setting file from the collection of setting files to each of the at least two applications based on the one or more task descriptions.

8. The network monitoring system of claim 7, wherein

each of the one or more task descriptions includes an identification of a select setting file for each application that is included in the task description.

9. The network monitoring system of claim 1, wherein

the data collectors include applications that:

facilitate the collection of performance data from a network and

include performance monitoring capabilities that can be queried from the network management system.

10. The network monitoring system of claim 1, wherein

the data collectors include applications that:

facilitate the collection of configuration data from a network, and

include configuration monitoring capabilities that can be queried from the network management system.

11. The network monitoring system of claim 1, wherein

the data analyzers include applications that provide at least one of:

flow analysis,

failure analysis,

security analysis,

network differences, and

network validation.

12. The network monitoring system of claim 1, wherein

the automation engine is configured to:

import network configuration data, via the one or more data collectors, and

determine differences in the network configuration data from a reference set of configuration data, via the one or more data analyzers.

13. The network monitoring system of claim 12, wherein

the automation engine is further configured to

issue one or more reports based on the differences, via the one or more data reporters.

14. The network monitoring system of claim 13, wherein

the automation engine is further configured to:

import network performance data, via the one or more data analyzers, and

include some or all of the network performance data in the one or more reports.

15. The network monitoring system of claim 1, wherein

the automation engine is configured to:

import network configuration data, via the one or more data collectors, and

determine conformance of the network to one or more design rules, based on the network configuration data, via the one or more data analyzers.

16. The network monitoring system of claim 15, wherein

the automation engine is further configured to

issue one or more configuration-error reports based on the conformance of the network to the one or more design rules, via the one or more data reporters.

17. The network monitoring system of claim 16, wherein

the automation engine is further configured to:

import network performance data, via the one or more data analyzers, and

include some or all of the network performance data in the one or more reports.

18. The network monitoring system of claim 15, wherein

the one or more design rules are configured to indicate latent problems in configurations of devices in the network that will adversely affect the network, based on the imported network configuration data.

19. A method of automating network analysis, comprising:

configuring an automation engine to;

import network configuration data from one or more devices on a network,

analyze the network configuration data to identify differences from a reference set of configuration data, and

provide a report of the differences and

enabling the automation engine.

20. A method of detecting network configuration errors, comprising:

configuring an automation engine to;

import network configuration data from one or more devices on a network,

analyze the network configuration data to identify configuration errors, based on one or more configuration rules, and

provide a report of the configuration errors, and

21. The method of claim 20, wherein

the configuration rules are configured to indicate latent problems in a configuration of a device that will have a negative impact on network performance.

22. A method of monitoring a network, comprising:

creating one or more task definitions that facilitate control of;

one or more data collectors, and

one or more data analyzers; and

configuring an automation engine to process the one or more task definitions to effect the control the data collectors and data analyzers, and

enabling the automation engine.

23. The method of claim 22, wherein

enabling the automation engine is based upon an occurrence of an event,

the event including at least one of:

a user-induced event,

a timed event,

an anticipated event,

an anomalous event, and

an alarm event.

24. The method of claim 22, wherein

configuring the automation engine includes identifying one or more setting files from a collection of setting files to effect the control of at least one of the data collectors and data analyzers.
