Abstract

A system for monitoring and measuring web applications by a user monitors a web site from multiple points of presence and alerts the web site operator when problems are detected. The system may be used in both corporate intranets and by web site operators. It provides alert information when a web site is not responding, when outages occur, monitors availability, and provides information as to the cause of the problems. The system operates by probing web applications at a chosen frequency from several locations simultaneously, which is called variable simultaneous angulation.

Claims

1. A method of testing web applications comprising the steps of:

simultaneously addressing a web site from three or more locations to test said web site for (a) secure sockets layer negotiation time, (b) connect time, (c) redirect time, (d) first byte time, (e) content download time, and (f) total bytes;

analyzing the results of said tests at each of said three or more locations; and

reporting said results.

2. The method of claim 1 further including the step of establishing a threshold representing a minimum number of said three or more locations, which have to report predetermined test results before said test results are deemed to indicate an error condition at said web site.

3. The method of claim 2 further including the step of testing said web site for response time by comparing a predetermined desired response time with the response time obtained from said web site and indicating the results of said comparison.

4. The method of claim 2 further including the step of calculating the exponential moving average of said test results, which do not indicate error conditions at said web site.

5. The method testing a web site for predetermined performance criteria comprising the steps of simultaneously sending the same test signal to said web site from three or more separate locations;

and analyzing the test results.

6. The method of claim 5 further including the step of establishing an error determination threshold for said test results for determining how many of said test results must indicate an error condition before said test is deemed a failure of said web site.

7. The method of claim 6 further including calculating the exponential moving average of at least ten separate test results, which do not indicate a failure of said web site.

8. A computer system for testing a web site simultaneously from three or more locations comprising;

controller means in the form of a multithreaded Java based program for driving all processing by determining which probes are ready to run;

at least three remote probe listening means for receiving requests from said controller;

database means connected to said controller for storing data;

a web server containing probe definition means for describing testing information for said website;

probe definition interface means connected to said probe definition means for enabling a user to construct said probe definition, reporting interface means for displaying and reporting system and testing information, registration interface means for enabling only designated users to access said system, and remote probe XML document means for collecting test results for each probe.

9. The computer system of claim 8 wherein said controller means includes means for determining which probes are ready to run, means for constructing simultaneous threaded requests to remote probe listeners which contain the probe definition, means for receiving responses from remote probe listeners, means for applying error logic and an error determination threshold to the results, means for updating said database with said results, and means for constructing and sending alerts.
