[SOLVED]RRD file cacti graph does not match realtime data

[eholz1]

Hello All,

I have question on cacti graphs, I have a standard cacti graph for interface using In/Out Bits/sec.
It is a nice graph - show a max input of about 114 MB. The time frame is for 1 week.
The realtime option for the same interface shows up to 700Mb/sec.

Why does not the standard (non-realtime) graph so the flow when it goes up to 700mb?
iS this a template issue? both graph and datasource?
I am running cacti-1.2.7 (and 1.2.9) on Red Hat 7. I am using 5min for the poller setting and 5min for the cron setting.

What would happen if I changed poller to 30sec and cron to 30sec?

I am open for suggestions -

SOLVED: use 64 bit counters for graphs
