Hello, I am somewhat confused by the output of a graph I am working on. Here are the RRA constructs:
DS:TXDPKTS:GAUGE:120:U:U \ DS:RXDPKTS:GAUGE:120:U:U \ RRA:AVERAGE:.5:1:288 Here are the pertinent graph parameters DEF:tx=data.rrd:TXDPKTS:AVERAGE \ DEF:rx=data.rrd:RXDPKTS:AVERAGE \ CDEF:drops=tx,rx,- The RRAs for tx are always 50. I am sending out 50 ICMP echoes. The rx is usually 50 with all others being 49. I have verified this by inspection using rrdfetch. What is confusing to me is that no matter what I do, I always seem to plot .5 instead of 1. I assume that the CDEF above will either b 0 or 1 based on stated values of rx and tx. Yet when I plot the graph, it always plots it at .5 no matter how I try and manipulate the y-axis (I tried -u with different values, --unit-exponent 0, etc). If I change CDEF to: CDEF:drops=tx,rx,-,2,* It works as required (although I am not certain why). Any explanation would be appreciated. And is there any way to print out a CDEF calculated value to track what is going on?
