Attach another nodes_exporters about prometheus HOT 10 CLOSED

Hi @davidmir Are you adding the targets by IP or hostname? Hostname makes it much easier to differentiate within Grafana. Could you provide a query you are using in Grafana?

from prometheus.

Hi, I'm using the hostnames. This are my targets on prometheus.yml:

• targets: ['localhost:9090','cadvisor:8080','node-exporter:9100','api.myapp.com:9100']

I'm using the Grafana Docker Dashboard. I have to make some changes in order to attach more nodes to the dashboard?

Thanks

@davidmir if you are interested in node metrics, I can recommend https://grafana.net/dashboards/22 which is a Dashboard for a single node based on node-exporter and you can select the node with a dropdown. For the host/node metrics I use this one and for container metrics I use either Brian/my dashboard.
Theres also https://grafana.net/dashboards/405 now which has even more node metrics (also based on node-exporter). But I havent used it yet and cant tell more about it.

My question goes in this direction: I have on another remote machine docker containers running. If I start cadvisor and node-exporter on that machine and add this machine to the targets they should not appear in Grafana?

from prometheus.

@davidmir ah ok, I understand. so then you also need to run cadvisor on that other node and add it as target. cadvisor collects the container metrics whereas node-exporter collects the hosts metrics.

@philicious I'm already doing it. however it detects that the cadvisor continues below (i'm using the image in this repository). It may be that he was running in the container docker (network problems)?

from prometheus.

@davidmir ok so lets sum up so I get a better understanding of the setup:

• you have node-exporter + cadvisor running on that second node?
• and both are configured to send to your central prometheus ?
• and in prometheus /targets all targets (=2x node-exporter + 2x cadvisor) are green and up ?

PS: the docker-compose.yml wasnt made for multi-node setup.
however for "Swarm Mode" there is work in progress.

Hi @davidmir is this now resolved? Can we close this?

Hi,

I'm interested an out of box solution for docker 1.12.3 swarm mode . I use service to deploy containers , and how thus this monitoring setup help . I tried to run cadvisor as service but then this will be load balanced by swarm mesh network .Please document the steps , if it can help

Hi @ppraj I would wait for 1.13 as I believe Prometheus will be integrated as an exporter which would resolve your issue. I've heard this should hit 1.13 - moby/swarmkit#1284
