node-exporter fails

[Tamar]

Hi,

I am trying to run node-exporter on several servers.

For all servers but one, node-exporter started successfully using the command:

docker run -p 9100:9100 \

--name node_exporter \

 -v "/proc:/host/proc"  \

 -v "/sys:/host/sys" \

 -v "/:/rootfs" \

 --net="host" prom/node-exporter \

 --path.procfs /host/proc \

 --path.sysfs /host/proc 

--collector.netclass.ignored-devices \

 --collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

For one server only I get this error when running the container:

level=error ts=2021-03-03T06:56:28.725Z caller=collector.go:161 msg="collector failed" name=netclass duration_seconds=5.9668e-05 err="could not get net class info: error obtaining net class info: cannot access /host/proc/class/net dir open /host/proc/class/net: no such file or directory"

Any idea how to overcome this?

Thanks,

Tamar
