@grin To expand a bit further, all I need is a simple tool to collect some metrics periodically, push it to #riemann, which I can then query from a custom built dashboard.

No permanent metric storage, no cluster support, no scalability, no complicated filtering and data transformation, no compatibility with other systems, no ad-hoc queries, no alerts, no history. Nada. Just real-time stuff on a dashboard.

End result looks like the image attached, and this is pretty much it. I don't need more.

My #rspamd can now export metrics to #Riemann. It's a bit fragile at the moment, and I need to improve Riemoon a bit, but if all goes well, I'll open a pull request within a week o so.

Went pretty smooth, all things considered. I expected it to be a little more challenging, but happy it wasn't.
