Hmmm... The `--test-parameter=ping_hosts=gstatic.com` information appears in the command-line summary but not in the charts. Is this correct?
If so, the charts display significantly different latency depending on which -H host gets used. The Terminal display (bottom) shows fairly consistent ping times and transfer rate measurements using either of the two hosts.
This raises two questions:
1. Could flent charts use the `--test-parameter=ping_hosts=...` instead of values from the -H host?
2. Why is there a discrepency between the `--test-parameter=ping_hosts=...` reading (showing 30-38 msec in my tests) and a separate, concurrent fping test (see original post, where it was running 20-22 msec)?
Thanks.
**Test to flent-fremont.bufferbloat.net gives latency > 100 msec:**
**Test to netperf.bufferbloat.net gives latency 55-65 msec:**
