Hello,
First of all, thanks for the great product! I setup Grafana to monitor our system and the datasource is InfluxDB. We define two tags: server and node, and many nodes belong to one server. Show below:
> SHOW TAG VALUES FROM x_memory WITH KEY=server
name: x_memory
key value
--- -----
server host50
server host51
> SHOW TAG VALUES FROM x_memory WITH KEY=node where server='host50'
name: x_memory
key value
--- -----
node node10
node node11
node node12
I want the cascaded tags. If I change the server, and node tag only lists the available nodes. I have tried below and failed.
SHOW TAG VALUES FROM erlang_memory WITH KEY=node where server =~ /$server$/
Could you please tell me now Grafana support the cascaded tags? if yes, how can I setup?
