Abstract

Software, systems and methods for managing a distributed network. For a given distributed device, the software includes a transaction monitor configured to identify transaction start times and stop times, and a resource consumption monitor configured to determine how much bandwidth is consumed by the distributed device during performance of a network transaction initiated by the device.

Claims

1. A distributed computer network, comprising:

a plurality of distributed computing devices interconnected via a network link, where each of the computing devices is configured to run an application program and network communications software, and where the network communications software operatively couples the application program and network link;

a plurality of agent modules, each agent module being associated with one of the plurality of distributed computing devices such that the agent modules and computing devices are in a one-to-one relationship, each agent module being loaded into and operable from a memory location of its associated computing device, each agent module including;

a response time sub-module configured to monitor the application program of its associated computing device to determine response times for transactions involving data flows over the network link; and

a resource consumption sub-module configured to monitor data flows within a network communications data path defined in part through the network communications software, where such monitoring of data flows is performed to determine how much bandwidth on the network link is being consumed by the computing device with which the agent module is associated.

2. The network of claim 1, where the response time sub-module is configured to receive event notifications from a browser application program so as to determine response times for transactions initiated by the browser application program.

3. The network of claim 2, where the network is configured to correlate the response time for each transaction with bandwidth consumption data obtained by the resource consumption sub-module for such transaction.

4. Software for monitoring a computing device coupled within a distributed network, comprising:

a transaction monitor configured to determine response times for network transactions initiated by a user of the computing device, where such transaction monitor is configured to determine response times for transactions involving both single and multiple targets;

a resource consumption monitor configured to monitor data flows associated with transactions monitored by the transaction monitor, where the software is configured to correlate monitoring by the transaction monitor and resource consumption monitor so as to determine how much network bandwidth is consumed for each network transaction.

5. The software of claim 4, where the resource consumption monitor is configured to interact with a socket object adapted to operatively couple an application program running on the computing device with a network link.

6. The software of claim 4, where the computing device includes a layered protocol stack for effecting network communication, including a transport protocol layer, and where the resource consumption monitor is configured to monitor network data flows of the computing device at a transmission point between an application program running on the computing device and the transport protocol layer.

7. The software of claim 6, where the resource consumption monitor is configured to hook into a socket object interposed between the application program and the transport protocol layer.

8. The software of claim 4, where the transaction monitor is configured to receive event notifications from a browser application program so as to determine response times for transactions initiated by the browser application program.

9. The software of claim 8, where the event notifications include commencement of downloads required for a transaction.

10. The software of claim 8, where the event notifications include completion of downloads required for a transaction.

11. The software of claim 8, where the event notifications include completion of document loads required for a transaction.

12. The software of claim 8, where the event notifications include completion of browser navigation tasks required for a transaction.

13. The software of claim 4, where the software is configured to register the transaction monitor with an operating system of the computing device, such registration causing the transaction monitor to be classed as an object that is to receive event notifications from an application program running on the computing device, and where such event notifications correspond to initiation and completion of network transactions.

14. The software of claim 4, where the resource consumption monitor interacts with the transaction monitor to create a record for each network transaction, such record including quantification of bytes sent out to the distributed network and bytes received in from the distributed network by the computing device during the network transaction.

15. The software of claim 14, where each record further includes identifying data for each remote device involved in data flows of the network transaction.

16. The software of claim 14, where each record further contains data identifying a user of the computing device during the network transaction.

17. The software of claim 14, where the software is configured to periodically transmit records over the distributed network for processing at a centralized network management software program.

18. A method of monitoring a distributed computed device operatively coupled with other distributed computing devices via a network link, comprising:

determining a start time of a network transaction initiated at the distributed computing device;

determining a stop time of the network transaction, where the stop time corresponds to completion of the network transaction; and

monitoring data flows on the network link associated with the network transaction to determine an amount of bandwidth consumed in connection with performance of the network transaction.

19. The method of claim 18, where monitoring data flows includes determining a number of bytes sent by the distributed computing device during performance of the network transaction.

20. The method of claim 18, where monitoring data flows includes determining a number of bytes received by the distributed computing device during performance of the network transaction.

21. The method of claim 18, where monitoring data flows includes determining a number of bytes sent and received by the distributed computing device during performance of the network transaction.

22. The method of claim 18, where the distributed computing device communicates over the network link using a layered network communications stack, and where monitoring data flows includes monitoring the distributed computing device at a data transmission point between an application program running on the distributed computing device and a transport protocol layer of the layered network communications stack.

23. The method of claim 18, where the network transaction is initiated by an application program running on the distributed computing device, and where determining a start time and a stop time of the network transaction is performed using a software module configured to hook into the application program and receive event notifications from the application program corresponding to initiation and completion of transactions.
