label_values multi column

[Danny de Waard]

Is there a way to create a dashbord label_vlue which shows 2 columns?

For a dashboard i have a label_value like so:
label_values(node_exporter_build_info{job="node_exporter_metrics"}, instance)

Which shows a list of ip:port in the dashboard to choose from.
What i would like is that it also would show the host label.

Like ip:port - host.

Just because hostnames are easy to recognizxe and ip numbers are not....

I don't think that's possible using label_values() at least. Have you considered using two variables, one for hostname and one for ip:port, filtering the ip:port by selected hostname(s)?

[Danny de Waard]

The variables now defined in my dashboard are:

Variable                Definition
datasource          prometheus

instance               label_values(node_exporter_build_info{job="node_exporter_metrics"}, instance)

host                      label_values(node_exporter_build_info{instance=~"$instance"}, host)

So they show up as 3 selctions in my dashboard.
What i would love is that i could combine a dropdownlist with ip:port_host so i know which host i'm choosing.

You could say, just change the selection method from instance to host, but this dashboard is called from another dashboard on instance... :)

Hi,

I have almost the same problem.

I have two Traefik instances. The metrics of those two are going to one prometheus instance. In prometheus.yml, I have defined two jobs under the scrape_config and now in grafana I want to separate the services that coming from Traefik-A from the services coming from Traefik-B.I tried to use dependent variables as below:

label_values(up, instance)

label_values(up{instance="$instance"}, service)

But it doesn't show the proper values but "none"! I tried other combinations but no luck.

You guys have any idea?

Thanks
