Help me please! I have virtual machine. Server Ubuntu 18.04 and install node-exporter prometheus under docker. On server i have several disks.. But in metrics i see identical values from different disks. Please help, what`s wrong? thanks!
If you look at the Docker instructions in the node_exporter README you can see that you're missing the process settings. Add pid: "host"
. You can also simplify the volume mounting.
node-exporter:
pid: "host"
volumes:
- /:/host:ro,rslave
command:
- '--path.rootfs=/host'
