Yes. If you want to collect several data points in a single .flent.gz, the timeseries aggregator is not going to work. You'll have to use the iteration aggregator (set AGGREGATOR='iteration' in the test config file), and use a different runner that outputs the ELAPSED_TIME as a single data point. I think it should be enough to subclass the netperfdemorunner, and redefine parse() to call the parent, pull out the ELAPSED_TIME metadata, and return that. -Toke -- You are receiving this because you are subscribed to this thread.
