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

saiharshitachava commented 5 years ago

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
```

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
