Riemann is also a rather heavy server load just to push webhook events to a database. Requires some effort to scale. Godot (Node app that aims to be Riemann API-compatible) seems to be a better option for smaller scale operations.
Right now the solution for many CI and webhook servers is to push events to Hipchat. That does not seem to be the most reliable or efficient way to triage issues.
How are other small to midsize businesses (i.e. those without dedicated devops) managing this architecture?
