What is the meaning of "Make Per 5 Minutes" in CDE

[saintares]

Hi there,

I have one network device which can give me total connections for certain hosts since reboot via SNMP.

I had setup cacti to get those value and cacti work properly. From the log file, I can see that the cacti is getting correct value from the SNMP device.

Then, When I go to plot the graph in cacti, the graph have some problems. The plotted figure did not represent current number in the SNMP device.

But when I enabled "Make Per 5 Minutes" CDEF function on the graph. The graph show correct result.

Anyone give me some advice?

By default rrdtool likes to show everything on a "per second" basis. Sometimes this does not make sense, especially when it is something that does not occur very often. I mean how useful is '80 m' when looking at a graph...

Either way, the "Make per 5 Minutes" CDEF simply multiplies the stack by 300, thus making it "per 5 minutes".
