Netflow Sampling Rate on asr9K

jstanky
Level 1
Level 1

I have a  few 9k's and are about to turn up Netflow and was curious about sampling rates.

I have the following line cards

A9K-8T-L
A9K-MOD80-TR 
A9K-MOD160-TR

Does it matter what RSP's I have? I have RSP-440's and RSP-880's?

Is there a way to monitor the CPU's and or memory on each line card? Do I need to monitor this?

I am trying to optimize the sampling rate and have heard many different rates.

Is there a safe number? I have been told 1 in  2000 is good but one of our vendors is indication we need 1 in 1000.

Any guidance would be great
