CHECK_TANG(1)

💖 CHECK_TANG(1) 💖

okay bestie, welcome to the manual page for check_tang — that's section 1 of the manual, so you already know it's giving "user commands" energy. it's a Nagios plugin for Tang and it's literally here to keep an eye on your Tang server so you don't have to. 🫶

✨ SYNOPSIS ✨

tang -u URL

that's it. that's the whole vibe. one URL and you're off. 💅

🌸 OVERVIEW 🌸

so, this Nagios plugin for Tang? it lets Nagios monitor a Tang server for its basic functionality and its performance metrics. iconic behaviour, honestly. 🎀

you run the plugin by just handing it the base URL of the Tang service. nothing else. no cap. ✨

and then the plugin runs through this whole checklist, like a little to-do list of trust:

1. Downloading the advertisement.
2. Verification of advertisement semantics.
3. Verification of signatures for all advertised signing keys.
4. Verification of key exchanges for all advertised exchange keys.

if any of those tests fail, an error gets generated. full stop. no success, no vibes. 😭

but if everything passes?? oh we ate. 🍓 the plugin outputs these performance metrics:

• adv — time it took to fetch the advertisement (in μs).
• exc — average time of all key exchange operations (in μs).
• nkeys — number of keys in the advertisement.
• nsigk — number of signing keys in the advertisement.
• nexck — number of exchange keys in the advertisement.

look at all those numbers. main character metrics. 👑

🦋 EXAMPLES 🦋

a simple test against a localhost Tang server:

$ check_tang -u http://localhost/
OK|adv=21430 exc=44587 nkeys=2 nsigk=1 nexck=1

and that right there? that's the OK of it all. chef's kiss. 💚

and that's the whole page, bestie!! 🌸 this was CHECK_TANG(1), living in section 1 of the manual, and it came from the CHECK_TANG(1) footer because that's literally all it says down there — no date, no version, just the name, standing there serving absolute minimalist main character energy. 💅✨ go monitor something. 🦋
