HAPROXY_LOG_ANALYSIS(1)

💖 NAME 💖

haproxy_log_analysis — generate aggregate statistics from HAProxy HTTP logs ✨

---

🌸 DESCRIPTION 🌸

okay bestie, buckle up 🎀 this lil icon reads your HAProxy HTTP logs and spits out aggregate statistics about them. that's the whole vibe. here's how you actually call it:

usage: haproxy_log_analysis [-h] [-l LOG] [-s START] [-d DELTA] [-c
COMMAND]

[-f FILTER] [-n] [--list-commands]
       [--list-filters] [--json] [--invalid]

ngl the usage block is giving "I was reformatted and nobody fixed me" 😭 but it's exactly what it is, so we're keeping it verbatim. no cap.

Analyze HAProxy log files and outputs statistics about it 💅

---

✨ options ✨

• -h, --help — shows this help message and dips out (exits). the classic. 🫶
• -l, --log LOG — the HAProxy log file you wanna analyze. pick your fighter 📂
• -s, --start START — process log entries starting at this time, written in HAProxy date format (like 11/Dec/2013 or 11/Dec/2013:19:31:41). at minimum you gotta give it the day/month/year, okay? any value you don't specify just falls back to its base value (so hour defaults to 00, etc.). use it together with -d to limit how many entries get processed. ⏰
• -d, --delta DELTA — caps the number of entries to process. write the time delta as a number plus a time unit, e.g.: 1s, 10m, 3h or 4d (that's 1 second, 10 minutes, 3 hours or 4 days — cute, right?). pair it with -s to only analyze that specific time delta. and if you don't give a start time, it just uses the time on the first line instead. ⏳
• -c, --command COMMAND — a list of commands, comma separated, to run on the log file. wanna know all the options? run --list-commands bestie. 🧾
• -f, --filter FILTER — a list of filters to apply on the log file. pass them comma separated, with any parameters hanging out inside square brackets, like ip[192.168.1.1],ssl,path[/some/path]. go check --listfilters for the full list of them. 🔍
• -n, --negate-filter — flips your -f filters so they work the other way around, i.e. if you pass the ssl filter, instead of showing only ssl requests it'll show non-ssl traffic. same energy with the ip filter: everything but that ip you passed gets used. 😈
• --list-commands — lists every command available. the whole menu, served fresh. 📜
• --list-filters — lists every filter available. equally iconic. 🎀
• --json — output results in json. for when you want your stats machine-readable, iykyk. 🤖
• --invalid — prints the lines that couldn't be parsed. heads up though: if you mix it with the print command, their output gets mixed together. you've been warned. 💀

🌈 reminder from your local unix bestie: every flag above is doing exactly what it says, nothing more, nothing less. read the caveats, respect the caveats, slay. 💅
