We use AWStats to report on response times in milliseconds, using the ExtraSection feature. We have recently noticed that some calls to our web service are responded to nearly instantly and record 0 milliseconds in our access logs. These 0 values are not being counted or reported by awstats.
In anticipation of the obvious requests for clarification, here is the definition of the extraSection I have that is not giving me zero values:
ExtraSectionName1="API Response Time"
