Collectors Data Format
All the collectors produce data on stdout in the same standard form:
host timestamp variable value
If the variable
is for something like network interfaces,
where the host can have several of them, the data will look like:
host timestamp variable:instance value
Having all the collectors using a standard form permits a single
updating program, updater, to process the data from them all, and
also means that I can write a new collector without needing to change
the updater.
