I don't pretend to understand the metadata - there is a lot stuff in the JSON file - but I don't think including the information in the filename would be necessary. I don't foresee a transition problem here. Flent can continue to default to using the -H host for its latency measurements. The new version's results should be comparable to results from a months-ago run with the same network conditions. In the case when someone explicitly uses the --use_this_host_for_default_latency option, Flent will of course preserve that flag in some new metadata and the charts will look different. But the person running the test will know about that flag and can take that into account. (Or am I missing your point...) Thanks. -- You are receiving this because you are subscribed to this thread.
