ENUM NFT_LOG_LEVEL(9)

💅 enum nft_log_level(9) — like, the whole nf_tables log-level situation

okay so bestie, gather round. this is a page out of the Kernel API Manual and it's about enum nft_log_level — which is literally just the list of log levels that nf_tables uses. that's it. that's the whole vibe. it's giving "severity menu at the netfilter café" and honestly? iconic. 👑

---

✨ NAME ✨

enum nft_log_level — the nf_tables log levels, no cap. this enum is the entire mood board of "how loud do you want your log message to be". 🎀

---

🌸 SYNOPSIS 🌸

here's the shape of it, copied exactly so you can trust me:

enum nft_log_level {
    NFT_LOGLEVEL_EMERG ,
    NFT_LOGLEVEL_ALERT ,
    NFT_LOGLEVEL_CRIT ,
    NFT_LOGLEVEL_ERR ,
    NFT_LOGLEVEL_WARNING ,
    NFT_LOGLEVEL_NOTICE ,
    NFT_LOGLEVEL_INFO ,
    NFT_LOGLEVEL_DEBUG ,
    NFT_LOGLEVEL_AUDIT ,
    __NFT_LOGLEVEL_MAX

};

look at her. nine real constants and then __NFT_LOGLEVEL_MAX just vibing at the end doing sentinel duty. we love a boundary marker. 🦋

🧚 CONSTANTS 🧚

okay this is the part you actually need, so let me walk you through each one, from "the world is literally ending" all the way down to "just chatting". 🔥

• NFT_LOGLEVEL_EMERG — system is unusable. like, unusable unusable. the whole box is on fire, this is the loudest possible scream, main character energy in the worst way. 😭
• NFT_LOGLEVEL_ALERT — action must be taken immediately. not "when you get a sec", not "later bestie" — immediately. 🚨
• NFT_LOGLEVEL_CRIT — critical conditions. big deal, bad vibes. 💀
• NFT_LOGLEVEL_ERR — error conditions. something broke, but it's a normal Tuesday kind of broken. 🙈
• NFT_LOGLEVEL_WARNING — warning conditions. the little "hey… heads up" before things go sideways. 🫶
• NFT_LOGLEVEL_NOTICE — normal but significant condition. nothing's wrong, it's just noteworthy. mildly interesting slay. ✨
• NFT_LOGLEVEL_INFO — informational. pure "just so you know" energy. 🌈
• NFT_LOGLEVEL_DEBUG — debug-level messages. for the girlies who want to see absolutely everything. turn it on, get buried, regret nothing. 🐛
• NFT_LOGLEVEL_AUDIT — enabling audit logging. yes, it's a log level and it turns audit logging on. multitasking queen. 👑
• __NFT_LOGLEVEL_MAX — -- undescribed --. the manpage literally leaves this one blank, so I'm not gonna make up lore for it. it's the max sentinel, and the docs said nothing. we respect the silence. 🤐

anyway, that's the whole page! no footnotes, no hidden gotchas, just a very tidy severity ladder. this one ships from ./include/uapi/linux/netfilter, dated October 2026, and it's filed as enum nft_log_level(9) in the Kernel API Manual. go log something responsibly, bestie — and if you pick NFT_LOGLEVEL_DEBUG, that's on you. 💅✨
