Nice stats for an oft-loaded fq_codel based wifi mesh network with not a lot of fixes (besides disabling 802.11e at key points so far)! I have seen much, much, much, worse from most other meshes. > What frequency is smoke ping probing at? This is tunable, you know.

Intent is to deploy at 3 locations internally (at the middle of the mesh and two of the furthest end points), and to also be probing through the link from a box colocated with the gateway. Ran out of time to muck with it this week, was delighted with the dataset so far on a live network, would like to be able to compare mrtg and smokeping more directly however. > > Jim >> >> >> On Thu, Jul 11, 2013 at 10:31 AM, Richard A.
