Enhanced network timings

The problem: Response time metrics, such as network, client, or server response times, are not comparable to similar metrics from other tools.

The solution: The algorithms used by the Web Response Time agent to calculate network timings have been enhanced to provide more accurate metric values that more closely match values calculated by other common open source tools such as HTTPWatch. See the appendix in the Administrator's Guide for more information about these enhanced timings.

Disabling enhanced network timing

If you experience any problems with these enhanced network timings, for troubleshooting purposes you can disable these enhanced algorithms by editing the kfcmenv configuration file (see Location of configuration files) and modifying the following line:

KFC_USE_7201_TIMECALCS=Y

Set this parameter to N to disable the enhanced timings, if you need to diagnose a problem. Set this parameter to Y to enable the enhanced timings again.

Additional timing related issues

If you see abnormally large timing values, or expected transactions are not displayed, the Web Response Time agent might be waiting for the HTML connection to end. For some websites, it might take a significant amount of time for the HTML connection to end. If this is occurring for your website environment, ensure that the KFC_HTTP_MERGE_REDIRECT parameter in the kfcmenv configuration file is set to N, to cause the connection to end promptly.
