VM-CBSD-Poller
The README is used to introduce the module and provide instructions on
how to install the module, any machine dependencies it may have (for
example C compilers and installed libraries) and any other information
that should be provided before the module is installed.
A README file is required for CPAN modules since CPAN extracts the README
file from a module distribution so that people browsing the archive
can use it to get an idea of the module's uses. It is usually a good idea
to provide version information here so that people can decide whether
fixes for the module are worth downloading.
This polls the Bhyve VMs managed by CBSD and returns a hash with the found
data. The command that is wrapped is 'cbsd bls'.
This needs to be run as UID 0 in most installations, given the requirements
of the cbsd command and how it is installed.
