Does telegraf support etcd? or should we build a scripts that does that get the config parameters and then configure telegraf?

PS: So far I found influxdata/telegraf#193 , and influxdata/telegraf#651

I don't think telegraf support etcd directly, but I think we should be able to use confD
https://github.com/kelseyhightower/confd
It's a tool that is able to monitor an ETCD instance and generate dynamically configuration file of any sort. it would work with both fluentd and telegraf
If a value changes in ETCD, I believe it's able detect it and regenerate the configuration automatically.

Never used it but so far it looks perfect for the job
