passenger-memory-stats(8)

✨ passenger-memory-stats — NAME ✨

okay so bestie, this is a section 8 admin command (Administration Commands, periodt 👑) called passenger-memory-stats, and what it does is report a snapshot of the Apache and Phusion Passenger memory statistics. that's the whole vibe. it's giving "let me see what's actually going on in there" 💅

🎀 SYNOPSIS 🎀

passenger-memory-stats

that's it. no flags, no arguments, no drama. just run it. iconic behavior honestly 🦋

💖 DESCRIPTION 💖

passenger-memory-stats lets you easily analyze the real memory usage of Phusion Passenger and Apache. like, the actual real memory usage. not the fake one. 🫶

so here's the tea ☕ — process inspection tools like ps and top are useful, sure, they're fine, they're doing their best, no hate. but they rarely show the correct memory usage. the real memory usage is usually lower than what ps and top report. yes, lower. they be overreporting. it's not their fault, it's just how it is 😭

there are many technical reasons why this happens, but an explanation is beyond the scope of this page. we're not gonna get into it here bestie, that's a whole other conversation. the interested reader is referred to operating systems literature about virtual memory and copy-on-write. go read a book, it's good for you 📚✨

🌸 when you run this tool, the Private or private dirty RSS field shows the real memory usage of processes. that's the one you want. look at that field. that's your girl. that's the truth 💅

🌈 ENVIRONMENT VARIABLES 🌈

• HTTPD — the full filename to the Apache executable. by default, Passenger will attempt to autodetect the Apache executable for you, no effort required, slay ✨. but if autodetection fails for whatever reason (it happens, we don't judge 🙈), then Apache processes will not be shown in the memory statistics. and in that case, you may manually specify the location to the Apache executable using this environment variable. you got this 💪
