[smokeping-users] Using Smokeping to measure DHCP latency

[Peter Kristolaitis]

  Hi Rob;

If you're referring to this page:

http://smokeping.ucdavis.edu/smoke/cgi-bin/smokeping.cgi?target=Campus.Campus_services.Campus_MISC.Campus_DHCP-PING

then I would question what, exactly, it is that UC Davis is measuring, 
and how that compares to what you want to measure.    That target on the 
UC Davis page is labeled "DHCP Server PING" -- to me, that would suggest 
that they're doing a simple ICMP PING to the DHCP host, rather than 
testing the response time of the DHCP service itself.

I'm not aware of any way to measure DHCP service latency with Smokeping, 
or even any plugins to do so.  It would probably be possible to write a 
Smokeping module for it though -- one approach that comes to mind is to 
execute dhcping against the DHCP server and time the execution (since 
dhcping basically just reports a yes/no status).
