This crate contains some utilities for building nagios-compatible check scripts, some utilities for reading and dealing with system information on Linux, and several implementations of check scripts.
See src/bin for the scripts that exist. You can see all their --help
messages in
the script docs.
The utilities are pretty stable, but the linux system information should probably be moved into something like procinfo-rs, although the implementation here appears to be more complete and type safe than any of the other options out there.
