VMware perfSONAR Plots for Debugging Network Issues
As part of AGLT2's VMware setup, we have created three ESX-host specific perfSONAR instances running OWAMP (one-way latency measurements). They have regularly scheduled tests between each other and our physical hosted perfSONAR psum01. We can look at these results spanning a 24 hour period during which we upgraded from the Broadcom NetXtreme II 57711 NICs to the Intel X520 DA2 NICs.
