✨ vzcalc — calculate resource usage of a container ✨

ok bestie, welcome to vzcalc(8) from the Containers section 💖 this little cutie tells you how much of your host's resources one specific container is out here consuming. main character energy fr fr.

🌸 SYNOPSIS 🌸

vzcalc [-v] CTID

that's it. that's the whole vibe. one container ID and optionally a -v. 🎀

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this utility displays the share of the host system resources that a particular container is using. if the container is running, the current usage gets displayed.

🚨 IMPORTANT SIS — high utilization values (>100%) mean the system is overloaded, or the container has an invalid configuration. either way, not the vibe. go fix it. 💀

here's what each of the standard rows actually means:

  • Current — shows the amount of the resources consumed by the container at a given time. like, right now, in this moment, no cap.
  • Promised — shows the resources soft limit values that are "promised" for a given container. it's giving... pinky promise. 🤝
  • Max — shows the resources hard limit values "promised" for a given container. the absolute ceiling, periodt.

and if you pass the -v option, you unlock the bonus content ✨ and these extra rows show up too:

  • Low Mem — the part of memory residing at lower addresses and directly accessed by the kernel (this only makes sense for 32-bit architectures, just so you know 🧚).
  • Total RAM — total memory. the whole thing. all of it. 🍓
  • Mem+Swap — amount of memory available for applications (both RAM and swap space).
  • Alloc Mem — standard memory allocations made for applications in a container. this is a more "virtual" system resource than RAM or RAM and swap, iykyk.
  • Num. Proc — number of processes. how many lil guys are running in there 👑.

💅 OPTIONS 💅

  • -v — Display additional information. (the extra rows listed above! go get that bonus content bestie 🫶)

⭐ EXIT STATUS ⭐

  • Normally, the exit status is 0. slay. 💖
  • On error, the exit status is 1. 😭 not slay.
