StatsD (blog.librato.com)

Funny, me too, given how I was just researching server side locking and sqlite yesterday.

Yup! We actually linked to that from the article as an example C implementation. It's really solid and also has a Librato backend ;-). We're already using it on a several high-throughput services internally and it will probably warrant it's own post in the future.

Thanks for this! Looks really promising. I'm a huge fan of statsd, but it seems like something so much better suited to a single binary than a whole node setup.

We used that for a long time, but it stopped scaling at some point. We ended up building IMVU istatd, the highest performance real time counter database we know of. Github.com:imvu-open/istatd Could be a back end for statd, or an alternative entirely; your choice.

It's AWS-style metered and billed monthly based on the number of time-series or "data streams" you're sending us.
