Abstract

A method for Internet performance monitoring and analysis includes, by at least one data collection agent (DCA), a DCA being a computer operating on the Internet and configured with software that is controlled remotely from another location on the Internet, responsive to a request from another location, said request including an indication of a web page, collecting web page object-level data with said at least one DCA; measuring access to web page objects in the web page; and transmitting measured information about the access to the web page back to the location that made the request. The measuring includes one or more of: capturing non-speed based information including errors during download, source of content by IP address, and type of content that an object represents, and parsing and recognizing other objects referenced in a content returned that also need to be retrieved. The measuring utilizes an HTTP protocol to interact with a web server.

wherein the user interface is configured to graphically illustrate the information.

2. The system of claim 1, wherein:

at least a portion of the information is indicative of one or more times required to access each web page object.

3. The system of claim 2, wherein:

the portions of the information indicative of one or more times required to access each web page object are displayed in the form of a timeline for each web page object.

4. The system of claim 3, wherein:

the portions of the information indicative of one or more times required to access each web page object include information indicative of times required to perform one or more steps involved in accessing each web page object; and

the user interface is further configured to illustrate the information indicative of times required to perform the one or more steps as elements of the timeline for each web page object.

5. The system of claim 4, wherein the steps include one or more of the following:

resolving a DNS name of the object;

connecting to a server;

requesting the object;

waiting for a response;

downloading data; and

disconnecting from a server.

6. The system of claim 3, wherein:

the user interface is further configured to display non-durational information for each web page object.

7. The system of claim 6, wherein:

the non-durational information includes one or more of;

information indicating whether each web page object was generated by a secure server;

information indicating whether each web page object originated from an original server;

information indicating a type of each web page object; and

information indicating a number of errors encountered accessing each web page object.

8. The system of claim 3, wherein:

the timelines are scaled according to the total time required to access all web page objects.

9. The system of claim 1, wherein:

the user interface is further configured to display information indicative of a summary of the information.

10. The system of claim 9, wherein:

the summary of the information includes one or more of;

a total time required to access all of the web page objects;

a total size of all of the web page objects; and

a total number of web page objects.

11. The system of claim 1, wherein:

the user interface is further configured to provide summary information related to one or more servers providing access to the web page objects.

12. The system of claim 11, wherein:

the summary information includes one or more of;

a number of servers contacted;

a hostname of each server contacted;

an IP address of each server contacted;

a number of web page objects served by each server;

a number of bytes transferred by each server;

a number of images transferred by each server;

an average time required to send requests to each server;

an average time required to receive a response from each server; and

an average time required to connect to each server.

13. A method for performance monitoring and analysis through a computer network comprising:

measuring and collecting information indicative of the performance experienced accessing one or more web page objects, utilizing at least one data collection agent (DCA) in communication with a computer network;

graphically illustrating the information to a user.

14. The method of claim 13, wherein:

at least a portion of the information is indicative of one or more times required to access each web page object.

15. The method of claim 14, wherein:

the portions of the information indicative of one or more times required to access each web page object are illustrated in the form of a timeline for each web page object.

16. The method of claim 15, wherein:

the portions of the information indicative of one or more times required to access each web page object include information indicative of times required to perform one or more steps involved in accessing each web page object; and

the information indicative of times required to perform the one or more steps involved in accessing each web page object is illustrated as elements of the timeline for each web page object.

17. The method of claim 16, wherein the steps involved in accessing each web page object include one or more of the following:
