We don't want to ignore config that can mess up machines. In general
this should always fail evaluation, as you think you are changing
behaviour and don't, which can easily create run-time errors we can
catch early.
https://github.com/MindFlavor/prometheus_wireguard_exporter/releases/tag/3.1.1
This release adds a flag `-l` which takes an address where the exporter
is available. The default is `0.0.0.0` (previously, `0.0.0.0` was used
by default).
Please note that there are no dependency changes in Cargo and therefore
the cargo hash didn't change.
Prometheus2 does no longer support the command-line flag to specify
an alertmanager. Instead it now supports both service discovery and
configuration of alertmanagers in the alerting config section.
Simply mapping the previous option to an entry in the new alertmanagers
section is not enough to allow for complete configurations of an
alertmanager.
Therefore the option alertmanagerURL is no longer used and instead
a full alertmanager configuration is expected.
Since version 3.0 all allowed IPs and subnets are exposed by the
exporter. With `-s` set on the CLI, instead of a comma-separated list,
each allowed IP and subnet will be in a single field with the schema
`allowed_ip_<index>`.
This is a simple exporter which exports the information
provided by `wg show all dump` to prometheus.

This makes sure that when a user hasn't set a Prometheus option it
won't show up in the prometheus.yml configuration file. This results
in smaller and easier to understand configuration files.
We previously filtered out the `_module` attribute in a NixOS
configuration by filtering it using the option's `apply` function.
This meant that every option that had a submodule type needed to have
this apply function. Adding this function is easy to forget thus this
mechanism is error prone.
We now recursively filter out the `_module` attributes at the place we
construct the Prometheus configuration file. Since we now do the filtering
centrally we don't have to do it per option making it less prone to errors.
This results in a smaller prometheus.yml config file.
It also allows us to use the same options for both prometheus-1 and
prometheus-2 since the new options for prometheus-2 default to null
and will be filtered out if they are not set.
This results in a simpler service unit which doesn't first have to
start a shell:
> cat /nix/store/s95nsr8zbkblklanqpkiap49mkwbaq45-unit-alertmanager.service/alertmanager.service
...
ExecStart=/nix/store/4g784lwcy7kp69hg0z2hfwkhjp2914lr-alertmanager-0.16.2-bin/bin/alertmanager \
--config.file /nix/store/p2c7fyi2jkkwq04z2flk84q4wyj2ggry-checked-config \
--web.listen-address [::1]:9093 \
--log.level warn
