[rrd-users] RRDcgi example

Fri Aug 3 11:15:13 MEST 2001

Hi!

	I've tried to use "example 2" in the RRDcgi tutorial applied to my
routers, but I'm getting the follow error when opening the
http://mywebserver/test/scripts/example2.rrdcgi (this is not a valid URL!!)

*************************************************************************
	RRDCGI Example Page for 

	(...)

	[ERROR: opening 'routers/.rrd': Nosuch file or directory]

*************************************************************************

I understand the nature of the error: <RRD::CV RRD_NAME> is equal to null
string!! ... but I don't know why!

Any help would be appreciated.
