Alcatel-Lucent Ajaxtest Performance Tool Help Guide Author: Eric L. Edberg Ver:

This guide is very new (2/2014) and includes information necessary to understand and execute Ajaxtest.

Please submit items to include in this guide to the author above.

Data Transfer Using HTTPS

Ajaxtest defaults to using the HTTP protocol over port 80 when transferring files to/from remote servers using the GET or POST methods.  When you select the "Enable HTTPS" checkbox AJT will use HTTPS over port 443 during data transfer to/from the content servers.

The CMDS content servers are provisioned with "self-signed" SSL certificates built locally on each server.  These certificates were not provided by official Certification Authorities.  The first time a browser attempts to access a web page  from one of the CMDS content servers using HTTPS the browser will not "trust" the servers self-signed certificate and will present a pop-up warining  stating "This Connection Is Untrusted" or a similar message.  The tester must manually "trust" the site each time the browser restarts or perminantely add the certificate into their local certiciate store to prevent future warnings (recommened).

 Before testing HTTPS with Ajaxtest the browser must manually access each selected content server and provision the browser to trust the remote sites.

Follow these procedures to configure your browser to recognize the remote certificates.

URL List

Note:  this is only a partial list of pubic and internal lab content servers.  If you do not find a server with the exact same IP address or computer name you must manually construct the URL using the IP or server name as it appears in Ajaxtest's "Servers" list.

 

Sigma Metrics Exlusion

Ajaxtest will calculate and display performance metrics at the conclusion of a test or when Query / Analytics execute.  Test results may contain results that are considered exceptions and outliers that very should not be considered when calculating time and throughput averages, standard deviation, errors, etc since these outliers would skew results.  This is especially noticable when few tests results exist and the % Error On Mean is large.

Outliers are often easily identified when reviewing the results histogram.  A classic normal distribution is expected with few if any outliers.

An example of a data point that should not be included is a data transfer that timed out or "hung" during the test logging a data point that is > 5 Sigma from the mean.
