This separates graph creation and value retrieval. In case values
need to be computed or retrieved externally, value retrieval will
only happen when needed (e.g. calling the plugin without any
arguments), saving time, I/O and cpu cycles.
Plugin monitors nftables counters and can be configured to show
a subset of counters. Limiting output by type of counter (bytes
or packets) is also possible.
Plugin requires python3-nftables, which makes use of libnftables
and is part of Netfilter's nftables, but may need to be installed
separately. Plugin will bail out if the nftables module cannot be
loaded.
Plugin is built upon PyMunin, adapted for Python3. The version
listed in PIP is still using Python 2 syntax. Release of a Python 3
compatible version is pending.
