This adds support for gathering information about ipset lists by adding a new target
ipset
. This target brings two new metricsipset_entries_total
andipset_ips_total
. The entries metric just counts the number of entries in a list while the other resolves CIDR syntax and reports the amount of individual IPs (e.g. for 192.16.2.0/24).Also, there is a regex argument which allows ignoring specific ipsets. The reason is that sometimes processes create temporary short-term ipsets (e.g.
my-tmp-list345
) which we might happen to catch unintendedly.Disclaimer:
This is the first time I am touching Rust. So, if you see something that looks awkward, then it probably is exactly that. I am happy to improve based on review comments :)it
