I am trying to use MRTG to grab network stats (bits in / bits out) of a cisco 3524XL switch. The config file for MRTG is set to use: LogFormat: rrdtool and I have the global options set to "bits". When I graph using the rrdcgi utility, the Network stats look fine, but when I try to calculate the percent utilization , the graph doesn't look right. In the config file I have the following: --start end-1day --title="% Utilization for Switch Port #<RRD::CV PORT> (Daily)" --imginfo '<IMG SRC=/path/%s WIDTH=%lu HEIGHT=%lu >' --width 400 --height 100 --vertical-label "% Utilization" DEF:Var1=/...path to rrd file...:ds0:MAX DEF:Var2=/...path to rrd file...:ds1:MAX CDEF:Var3=Var1,Var2,+ CDEF:Var4=Var3,100000000,/ CDEF:Total=Var4,100,* AREA:Total#009900:"Percent Utilization" GPRINT:Total:AVERAGE:"Avg. %3.3lf%%" GPRINT:Total:MIN:"Min. %3.3lf%%" GPRINT:Total:MAX:"Max. %3.3lf%%\n"
According to the GPRINT statement, I think it looks correct, however I have a number (alot) of ports that are reporting the utilization below .01%. but the graph doesn't match, and the y axis doesn't show a percent scale. Instead it shows: 80 m, 60 m, 40 m, 20 m. What am I doing wrong?
