SNMP Informant Read/Write Queue

[Malus]

Hello!

We have a CACTI 0.8.7g in use. The host machine is debian based.

We would like to analyze the read / write queue using SNMP Informant.

The old scripts (http://forums.cacti.net/about10707.html) does not work for us.
RRDTools bring the following message:

If we assign a color, comes the following message:

RRDTool Says:

ERROR: parameter '#FFFFFFFF' does not represent a number in line LINE1:#FFFFFFFF:Free Space (Mb)

Can someone please help us?

Best regards,

Hey,

did you ever manage to figure this out?
thanks

[phalek]

It seems like you didn't select a data source for that Line (data source = none ?):

Code: Select all

LINE1:#FFFFFFFF:"Free Space (Mb)" \

should be e.g:

Code: Select all

LINE1:h#FFFFFFFF:"Free Space (Mb)" \

(note the little "h" in front of the color ).
