[rrd-users] Re: I need help to calculate % of max bandwidth !!!

[Iain Buchanan]

You could do it this way.  If anyone has a better way, please say so!

1. Draw the running % 'blind' so it doesn't show a line on the graph
2. GPRINT this value

You will of course have to choose from the min, max or average percent
values.  eg (ave):

(this is your data source)
DEF:trend=data.rrd:bitsin:AVE

(this is the percent, assuming your max bandwidth is a 56k modem)
CDEF:pctrend=57600,trend,/,100,*

(note no colour is specified so the drawing is done 'blind')
LINE1:pctrend

(now print the average of the percent of maximum bandwidth!)
GPRINT:pctrend:AVE:%.2f
