[rrd-users] Help with counter wrap

[Alejandro Diego Garin]

Hello !

I have problems with the counters and the wrap issue. My front-end solve
the problem of a reset checking the uptime but in case of counters wrap
I am with problems.

RRD database configuration:

	   "DS:testmeasure:COUNTER:1200:U:12500000"
           "RRA:MAX:0.5:1:288",
	   "RRA:MIN:0.5:1:288",
	   "RRA:AVERAGE:0.5:1:288"

please?

Thanks very much.
