Always scale a bandwidth graph to maximum interface bandwidt

[geertn444]

Hi all,

I want to scale my graphs to maximum interface bandwith + 20%

I have managed to draw a line at maximum interface bandwidth with the ifSpeed parameter from the SNMP query.
However, Cacti doesn't take this value into account to scale the drawing. It the load is low, the graph is scaled down and we don't see that maximum bandwidth line. I want the scale to be fixed at ifSpeed+20%, independant of the current interface load.

Can this be done ?
(note: every graph has another ifSpeed maximum)

regards,
Geert

It's actually at RRDTool issue..

Try playing with the Y scaling options in the graph template.

I have tried to scale with a parameter, but cacti won't allow anything other than a number in the field (see attachment). It does allow parameters in the title field , but apparently not in the scale field. Damned

Coming with cacti 0.8.8 (is already implemented in SVN). Sorry, not with 087c
