- add base structure - unify the proto metrics creation and propagation - implement arp and openvpn - refactor to meet the prom exporter standart - add instance label to the metrics - refactor the call chain - add gateway, unbound_dns and openvpn implementations - add gateway stuff - structure refactor; mod clean; cron implementation - implement cron in the collector; refactor utils in the opnsense package refactor names and implement option functions to disable collectorInstances add GH action workflows Create codeql.yml - clean fix stuff
