Hi folks,
I am a new Grafana and Prometheus user and I want to create 2 variables to generate a customizable bandwidth utilization graph: Device IP (instance) and Interface name (ifName).
I managed to make it work by creating the variables as type Query and using the following query statements:
label_values(instance) - for variable deviceip
label_values(ifName) - for variable ifname
The problem is that I want the “ifname” variable to load only the interface names contained in the “deviceip” selected (instance).
Could someone please lend me a hand?
Thanks,
Marcelo
