Riemann is top of our list to be implemented in an environment made up of PostgreSQL, Memcached, Python (Django) and Go.

But as Hekad has plugins for all of the above (except Go - but I'm sure it's possible): http://heka-docs.readthedocs.org/en/latest/architecture/inde...

Well I guess we'll now be evaluating whether Hekad looks like it might be a more promising fit.

I particularly like the bullet points on aggregation counters, filters and transformations. We'll have to see how they work in practise though. The docs are very pretty, but as is usual with early releases it seems a little difficult to picture the whole and how it will actually work in practise from the soup of detail that Sphinx spits out.

Unfortunately, the diagram you linked to is misleading; we don't have all of those plugins built yet. We've got a (quite rich) Python client (https://github.com/mozilla-services/heka-py) and a (rudimentary) Go client (https://github.com/mozilla-services/heka/tree/master/client) but Memcached and PostgreSQL connectors aren't yet in place. Fleshing out our plugin set (especially the inputs) is one of our highest priorities, so those should be coming Real Soon Now(tm). Contributions welcome!
