Ps: Node-exporter is running by docker
and Node-exporter is installed by

sudo docker pull prom/node-exporter

the version info is showed by

sudo docker run    prom/node-exporter      --version

node_exporter command line flags

I don't understand what command line flags is ?

Are you running node_exporter in Docker?

yes

What did you do that produced an error?

I am trying to run node-exporter as below:

sudo docker run         \
--network="host"            \
--pid="host"            \
-v "/:/host:ro,rslave"  \
prom/node-exporter      \
--path.rootfs="/host"

What did you expect to see?

node-exporter running

What did you see instead?

error info is as below

docker: Error response from daemon: linux mounts: Path / is mounted on / but it is not a shared or slave mount..

it seems casued by old version of docker .
and the solution is to run

 sudo docker run         \
--network="host"            \
--pid="host"            \
-v "/:/host:ro"  \
prom/node-exporter      \
--path.rootfs="/host"
