I made specific validator's metrics to prometheus


I add specific validator’s metrics on tendermint.
If you want to use it, see the guide on the Github.
And I add small tutorial about prometheus+grafana+telegram.
Also, I have a plan to implement metrics on cosmos-sdk.
However, I have a little problem.
Currently, it seemed that cosmos-sdk can’t recognize fast sync.
Without recognizing fast sync, metrics will be strange until finishing catching up.
I guess it can be solved by informing the end of catch up through ABCI’s SetOption function…
Do you have any better ideas?
