I have no data in the graphs.
In the error log I can see

sh: line 1: /dev/null: Permission non accordée (denied)

I'm newin using NetMRG, this is my first use.

Sorry for my bad english I'm living in Belgium !!!!!

I'm using a Debian sarge.
Version of NetMRG is Version 0.18.2.

Do you have write access to /dev/null? This is very odd for a linux installation. My permissions look like the following:

# chmod 666 /dev/null
$ ls -l /dev/null
-rw-rw-rw- 1 root root 0 2004-12-30 20:40 /dev/null

I don't have the crw ???

I will try like that

Thank for your help.

Tha's very odd; your /dev/null should be a character device. Try the following:

This is done, I have no more errors now. Just waiting if I have some date written in the graph.

The output you listed is normal; are you still not getting any graphs?
If this is the case, the first thing I would do is check the permissions on the directory where the RRDs are stored (/usr/local/var/lib/netmrg/rrd for a source install) to make sure the files are writable by the user netmrg runs as from cron. Commonly these files will get created as root if you do 'test runs' as that user, then the netmrg user can't write to the files.

If the permissions seem correct, try running 'netmrg-gatherer -sm' and posting the output here.

The rrd files are in /var/lib/netmrg/rrd/

the user is well netmrg but the group was my web server.
