Hey and thanks for your reply. This is done easily in the cscli with the 'decisions' command: https://doc.crowdsec.net/docs/next/cscli/cscli_decisions. 'sudo cscli decisions list' lists all local decisions as you request :-). If you want to look into a decision, 'explain' is your friend: https://doc.crowdsec.net/docs/next/cscli/cscli_explain or simply look in /var/log/crowdsec.log (on Linux).
I hope this answers your question. If not, you're welcome to ask again or join our Discord at https://discord.gg/crowdsec (which is by far the best way to get help fast).
