[rrd-users] Sudden spike in RRD graph

[Tay Chee Yong]

Hi all,

I have implemented a large scale RRD plotting on all of my edge routers. I 
am plotting the rate-limit traffic for my customers, but however, whenever 
I change the value of the rate-limit (eg. from 1Mbps - 2Mbps), there will 
be a sudden spike in the RRD graph, like the one shown in the attachment. 
Can anyone advise why is this happening, and what can I do to resolve this 
sudden spike?

And what does the 'P' in the graph means?

Hope someone can assist me on this.

Thanks.

Regards,
Cheeyong
