Is the query node_meta working which provides the hostname in the metrics

[Harshita]

I was trying to use node-exporter customized image and gave the below configs and deployed.
But I dint see the data populated in the Swarm Node overview dashboard

nodeexporter_eng:
image: stefanprodan/swarmprom-node-exporter:v0.16.0
environment:
- NODE_ID={{.Node.ID}}
volumes:
- /proc:/host/proc:ro
- /sys:/host/sys:ro
- /:/rootfs:ro
- /etc/hostname:/etc/nodename
command:
- '--path.procfs=/host/proc'
- '--path.sysfs=/host/sys'
- '--collector.filesystem.ignored-mount-points="^(/rootfs|/host|)/(sys|proc|dev|host|etc)($$|/)"'
- '--collector.filesystem.ignored-fs-types="^(sys|proc|auto|cgroup|devpts|ns|au|fuse.lxc|mqueue)(fs|)$$"'
deploy:
mode: global
placement:
constraints:
# Hostname of the first woker node!
- node.platform.arch == x86_64
networks:
- frontend

Same issue here :( This is the error for the node-exporter container :

invalid mount config for type "bind": bind source path does not exist: /etc/hostname

Any solution?

@jonathanmf that depends on your operating system, if it doesn't store the hostname in /etc/hostname then it won' be able to mount it.

@saiharshitachava if you query prometheus for node_meta what do you get?

In my case I forgot to add this in the command..- '--collector.textfile.directory=/etc/node-exporter/'

Its working now
