Percentages wrong

jrmann1999

I've tried playing with the graphs for netflow(rate vs % of interface), but they are reporting the wrong values.

 

NTA 3.7, Orion NPM 10.1.2

Link speed is an OC3, cisco router exporting netflow v5:

interface POS2/0
 ip address <redacted>
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip accounting output-packets
 ip flow ingress
 ip pim sparse-dense-mode
 load-interval 30
 no cdp enable
 max-reserved-bandwidth 90
 service-policy output pm_wan_out
end

ip flow-export source Loopback0
ip flow-export version 5
ip flow-export destination <orion server IP> 2055

Percentages in the attached screenshot are well above 100%, but you can see the individual line item entries show correct percentages, what is wrong?

By default long lived Netflow cache data is exported every 30 minutes.  This will cause some high peaks in the graphs since the flow data is exported at one time.  The following commands will help to reduce the peaks:

 

ip flow-cache timeout active 1 ( Breaks up long-lived flows into 1 minute fragments and smooths out the peaks and get a more accurate data representation on the graphs)

ip flow-cache timeout inactive 15 ( makes sure that flows that have finished are exported)

 

Hope this helps
