is there any consideration to use "_" when outputing to opentsdb?

[skygragon]

since opentsdb format doesn't have "field" as influxdb, so telegraf will create a new name like "metric_fieldName" to fit this gap. My question is: can we use '.' instead of '_' here? You see most metric are named in this pattern "xxx.yyy.zzz", so maybe use '.' makes more sense?

[skygragon]

or can we use a pre-defined placeholder like: "some.metric,tag1=xxx _=123", then it will skip this _ and use "some.metric" when outputing to opentsdb?

We would accept a PR that added an option in the output: separator="." or such.
