monitoring manifesto

monitoring: what I want

I've recently shifted from a straight engineering job to a job with a "dev/ops" title. What I have discovered in operations land depresses me. The shoemaker's children are going unshod. Operations software is terrible.

What's driving me craziest right now is my monitoring system.

what I have right now

What I have right now is Nagios.

monitoring proposal

Go here for the latest + some code.


An alerting engine for a metrics & monitoring system.

This is the same approach I wanted in my initial spike, only instead of writing a custom collector & using an existing alerting engine (riemann), I'm proposing using an existing collector (hekad) and writing the alerting engine.

uselessd -- what it says on the tin, plus a complementary kitchen sink and flat tire

So, what is it?

uselessd (the useless daemon, or the daemon that uses less... depending on your viewpoint) is a project which aims to reduce systemd to a base initd, process supervisor and transactional dependency system, while minimizing intrusiveness and isolationism. Basically, it’s systemd with the superfluous stuff cut out, a (relatively) coherent idea of what it wants to be, support for non-glibc platforms and an approach that aims to minimize complicated design.
