Feature: Memory graphs

Goal

Display a consistent and immediately understandable visualization of memory usage, custom-tailored to how Linux manages memory.

Related issues

Overview

• Cockpit's memory usage graphs includes the cache but makes no distinction
• How much RAM do I have?
• machines: amount of RAM and how it's used is separate

Containers

• Container memory usage
• No CPU, Memory Graphs on Kubernetes
• Explicitly deal with containers without resource monitoring.
• Combined memory graph should turn red when the limit is approached.

Services

• Resource graphs for all service tabs

Semi-related

• No obvious way to get back to System page from the CPU and Memory pages
• Switch from KiB/MiB to KB/MB in order to match CLI better?

Current implementations

Right now, Cockpit has multiple graphs of memory usage and:

• None of the memory graphs are consistent
• Memory graphs are wildly inaccurate, with regard to telling the story of how memory is being used
