This puts all collector-specific flags into their own namespace under
"collector.<collector-name>", and moves from camel case to dashes, which
is the standard in Prometheus land now.
Remove special tags necessary for gmond and runit collectors. All
collectors get built. Selection of which collectors to use continues to
happen via parameter.
Last login is disabled by default as it's broken on ubuntu 12.04
Interrupts is disabled by default as it's very granular and we'll have total interrupts from /proc/stat
Allow ignoring devices from diskstats, ignore ram and loop devices by default.
Use glog for logging.
This works by using a global array with references to NewXCollector
functions. Each collector appends to that array in it's init() function.
Which file gets build depends on the build tags:
To build only the ganglia exporter, you can do:
go build -tags nonative,ganglia
By default it will build only the native collector.
