How can I get more exact data-points from a visual studio load test? -
when load-testing in visual studio results reported snapshots of data using resolution in time indicated sample rate parameter. find desirable way @ results. more useful have actual timestamp of when happens rather timestamps constant interval. example page response time more useful have timestamp of when response received.
i obtain data exporting graphs csv. gives me data in form:
"elapsed time","page1time","page2time" "00:00" , "", "" "00:05" , "", "" "00:10" , "0,36325", "" "00:15" , "", "0,2825"
because of constant time-intervals used there large gaps in data no data points, general poor accuracy. rather prefer have timestamp each datapoint every page time contains both response time , timestamp:
"timestamp1","page1time","timestamp2","page2time" "00:09.654" , "0,36325", "00:14.345", "0,2825"
i don't need exact format above, format each point of data represented both it's own timestamp , y-axis value.
as last resort should possible implement own logging each request/response or other data need, save me lot of time if there simpler way data way want it.
as far know data recorded in load test database. sql database , can write own queries etc examine contents. there description of tables , columns in database; changes have been made more recent visual studio versions, blog best description available.
it may necessary set timing details storage
all individual details
in run settings.
logs of individual web tests have additional details. altering altering save log frequency completed tests
in run settings allows logs successful tests retained.
