[collectd] Collectd on RedHat with virtuall network devices !

[Michael Theurl]

Hello Collectd list,

I have the collectd on a redhat es4 system running with multiple network
devices:

* Vmare GSX hostonly network devices (vmnet0, vmnet1)
* Openvpn TAP/TUN devices
* and some eth0/1/2 controllers

The main problem is the only rrd file for the eth1 interface have
collected the bits !
the other rrd are created but the rrd database is zero. I use the
"traffic" file from the contrib folder.

As a sample i checked the database state with "rrdtool
info /var/lib/collectd/traffic-tap0.rrd"
the result was:

< - snip - >
rra[0].cf = "AVERAGE"
rra[0].rows = 1500
rra[0].pdp_per_row = 6
rra[0].xff = 2.0000000000e-01
rra[0].cdp_prep[0].value = 0.0000000000e+00
rra[0].cdp_prep[0].unknown_datapoints = 0
rra[0].cdp_prep[1].value = 0.0000000000e+00
rra[0].cdp_prep[1].unknown_datapoints = 0
< - snap - >

is it Possible that the collectd have some problems with virtual
network devices ?

here my collectd.conf:

< - snip - >
Mode    Local
DataDir   /var/lib/collectd
PIDFile   /var/run/collectd.pid
PluginDir /usr/lib/collectd

LoadPlugin cpu
LoadPlugin cpufreq
LoadPlugin load
LoadPlugin nfs
LoadPlugin swap
LoadPlugin traffic
< - snap - >

Is there a sollution for this problem ?

thanx for helping, 
cu

Michael
