Two hints:<br><br>1) When a host goes red, it always goes green after 28-32 seconds or 43-46 seconds.<br>2) When a host is red divide the number of seconds it has been unchanged by the amount of polls. You'll never get a a remainder greater then a minute.

<div></div>ARP can't be the problem - ARP will cache the result for 2 minutes
and clear it if unused. If the result is used and is valid again within
the 2 minutes, it is cached for 10 minutes. Hobbit polls every 30-45
seconds so ARP is not a problem. <br><br>Having switch from using hobbitping

there are warnings not to use hobbitping, but I don't understand how the
command line is getting such normal results while the graphs are getting such
high results. Does anyone know why this is? <br><br>Josh<br><br>

forget the ARP protocol -- if a destination is not in the local system's ARP

generates an ARP broadcast. The assumption (I guess) is that the
discarded packet will be retransmitted. You might look for the "knobs"

<div></div>Concerning fping options, I have some RRD graphs that show
enormous pings to some of our customer's (upwards of 800ms) because as the
radio doesn't pass any traffic it sits there and when someone first looks
for it, it acts kind of dumb. <br><br>What delegates how often the FPING
command is issued? I'm not looking for the arguments for fping
itself, but rather how hobbitd kicks fping into gear.<br><br>I would like
to increase the rate of the pings and see if that helps. I'm running
a continuous ping over night to see if that changes the graph or if it
really does spike to that outrageous height. <br><br>Josh<br><br>
