[c-nsp] Latency monitoring via RTR

[John Neiberger]

Brian,

That's very close to what I need, and it's enough to get me started.

Does anyone have a comprehensible explanation of lives, buckets, and
samples? :-)  I think I understand samples, which is just the number of
samples of data kept per ping, for example, if we were doing an icmp
echo probe. But I don't understand lives and buckets.

Also, does the responder have to be configured on the remote side for
this sort of probe?

thanks!
John

This may not be the test your looking for, I have not done much with  
RTR/SAA.
The above test flags pings over 500ms as "interesting".  It runs the  
test 1 time every
60 seconds, and its scheduled to start now and run forever.

to view the data you do "show rtr operational-state 10"
