Additional SunOS- (i.e. Solaris- and Illumos-) specific collectors for the Diamond metrics collection daemon.

Diamond is great, but it has very poor support for Solaris and SmartOS. This repo holds additional collectors suited to those platforms. I intend to cover system (global zone) collection and a subset of collectors for when you are a guest in, for example, the JPC.

My target endpoint is Wavefront, and I have a fork to Diamond with full Wavefront support which I hope will be merged into Diamond eventually.

Most of the metrics come from the Solaris kstat interface, and are accessed by a third party module. That needs to be checked out somewhere in your Python path.

As of right now these are being developed and tested on x86 Solaris 11.3. They mostly work with SmartOS, though sometimes in a slightly different way due to the subtle differences between the platforms.

At the moment I'm concentrating on a system view: that is, the state of the whole host as seen from the global zone. Local zones have different views and different needs, and working out how to elegantly address that is an interesting part of this project.

I deploy this by building a package which installs in /opt/diamond, containing a minimal Python build, with Diamond and its dependencies built in. (This is because otherwise you need a C compiler to pip install diamond, and I'm old-fashioned enough that I don't have C compilers where I don't need to have them.) So, you may have to tweak your PYTHONPATH or sys.path to include things which are specific to my environment.

If you want to deploy it properly, look in the package/ directory for information on how to build a standalone Python + Diamond + collectors package.

A test config for Diamond is supplied as diamond-test.conf, and there's a little wrapper script run.sh which fires up a test instance.

Diamond has an "archive mode" which is excellent for testing new collectors. The sample config in this repo writes a line to /var/tmp/diamond_archive.log whenever a metric is generated.

I'm trying to cover everything with tests. Methods have unit tests wherever they can, and collectors have functional tests built following patterns in the proper Diamond repo.

To run the tests use the top-level test.py script. This is copied from the Diamond repo, and hacked about until it worked. Because of the strong dependency on the kstat module, the tests will only work on a Solarish system.
