Why doesn't my IP SLA work for keeping history?

thomasdzubin · ‎06-02-2008

My ISP has been unreliable, so to get some hard numbers for them, I'm wanting to use my router to measure and record response times and jitter to my gateway address (aa.bbb.cc.d in the below config) So I did the following:

config t

ip sla logging traps

ip sla 1

path-echo aa.bbb.cc.d

history hours-of-statistics-kept 3

history buckets-kept 20

ip sla schedule 1 life forever start-time now

I wait a few minutes, then I do a "show ip sla history 1" but there doesn't seem to be any history recorded.

A "show ip sla statistics 1" DOES tell me the latest info (eg: "Latest RTT: 5 milliseconds") but I want to see a table of RTT results over a period of a couple hours...

Does anybody know what I'm missing?

You need to add history lives-kept to this collector. The default is not to collect history. See http://www.cisco.com/en/US/docs/ios/ipsla/command/reference/sla_01.html#wp1012465 for more guidelines on configuring history.

Actually it appears to have been the "history filter all" that I was missing.

Thanks for your suggestion, however.

It is working now.
