Hi, I´m making graphs with rrdtool, but I think that the the percentage values do not correspond the reality. I am using template graphs.mf without no alteration in expressions RPN.
Expressions: DEF_subnet_out_bytes = DEF:xsubnet_out_bytes=$(rrddir)/subnet.rrd:out_bytes:AVERAGE DEF_subnet_in_bytes = DEF:xsubnet_in_bytes=$(rrddir)/subnet.rrd:in_bytes:AVERAGE CDEF_subnet_bytes = CDEF:xsubnet_bytes=xsubnet_out_bytes,xsubnet_in_bytes,+ CDEF_subnet_Mbps = CDEF:subnet_Mbps=xsubnet_bytes,.000008,* In the graph: 'CDEF:div_Mbps_pct=subnet_Mbps,TOTAL_Mbps,/' The results: subnet_in_bytes = 128.319883 subnet_out_bytes= 4903.096164 subnet_bytes = 5031.416047 (IN+OUT) subnet_Mbps = 0.040251 (BYTES*0.000008) TOTAL_Mbps = 0.079754 div_Mbps = 0.272552 (subnet_Mbps/TOTAL_Mbps) <========== error But, using a calculator, 0.040251/0.079754 = 0.504689 I would like to know what´s happening?
