Add pod memory RSS enhancement

[kgibm]

The OpenShift Container Platform (OCP) web console shows a "Memory" column for pods that maps to container_memory_working_set_bytes. This Working Set Size (WSS) is useful but it includes active file cache and reclaimable kernel slab on Linux, both of which are reclaimable if needed, and this may cause user confusion and concern about potential memory leaks and sizing.

This proposal is to rename the "Memory" column to "Memory (WSS)" and add an additional column "Memory (RSS)" on Linux that maps to container_memory_rss that is the anonymous Resident Set Size (RSS). The RSS column is not added for Windows pods.

Summary by CodeRabbit

• Documentation
  • Added a proposal for displaying pod memory usage as separate Memory (WSS) and Memory (RSS) columns in the OpenShift web console.
  • Documented the distinction between working-set memory and anonymous RSS, including data sources, user benefits, goals, and testing considerations.
  • Clarified that Memory (RSS) applies to Linux pods and is excluded for Windows pods.

Hi @kgibm. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request changes only enhancements/console/memory-rss.md and an image. It adds no Ginkgo tests or test-title calls such as It, Describe, Context, or When. The proposal's example pod reference is documentation text, not a test name.

Full details: Microshift Test Compatibility

Explanation

PASS: The PR adds only a Markdown enhancement proposal and an image. The complete PR diff contains no Go or other test files and no added Ginkgo constructs such as It(), Describe(), Context(), or When(). Therefore, the MicroShift test-compatibility check does not apply.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The PR adds only an enhancement proposal and an image. It adds no Ginkgo e2e tests or executable test files. The proposal's “tests will be added” text is documentation, not a new test. Therefore, the SNO multi-node compatibility check is not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

The pull request adds only a Markdown enhancement proposal and an image. The diff from origin/master contains no deployment manifests, operator code, controllers, or scheduling configuration. The proposal describes console metrics and lists topology sections as N/A. Therefore, this topology-aware scheduling check is not applicable.

Full details: Ote Binary Stdout Contract

Explanation

PASS — the pull request changes only enhancements/console/memory-rss.md and its PNG image relative to origin/master. It adds no binary source, suite setup, initializer, or stdout-writing code. The OTE stdout contract is therefore not affected.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request adds only enhancements/console/memory-rss.md and an image. The diff contains no Ginkgo e2e test declarations or changed test files. The test plan describes future checks but adds no test implementation, IPv4 assumption, or external connectivity requirement.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request adds only a Markdown enhancement proposal and a PNG image. The added text contains no MD5, SHA1, DES, RC4, Blowfish, ECB, custom cryptography, or secret/token comparison logic. No cryptographic implementation or executable code changed.

Full details: Container-Privileges

Explanation

PASS: The pull request adds only a Markdown enhancement proposal and a PNG image. The diff adds no container or Kubernetes manifest, and the added patch contains none of the specified privilege settings or capabilities. The check is therefore inapplicable.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS. The complete PR diff adds only a Markdown enhancement proposal and a PNG image.

explicitly include /sys/fs/cgroup/memory/memory.stat, while preserving the
existing child-cgroup glob and cgroup v2 path.
- Around line 19-20: Update the memory column definitions in the proposal,
including the `container_memory_rss` description, to state that RSS represents
anonymous and swap-cache memory rather than anonymous memory alone; apply the
corrected wording consistently at both definition locations.

Covers the missing query, platform behavior, and test requirements.
