metrics: move the node-side services' families to their owners by ac-pplx · Pull Request #1540 · perplexityai/SPACE

ac-pplx · 2026-11-05T19:38:25Z

Summary

Second of three. The node-side services' families move into a metrics module of each recorder:

sbx-mgr: snapshot, sandbox::{vm,worker}, sandbox_eviction, stream_presence, and its reconcile apply, network-policy and credential-pull families.
node-mgr: byok, node_manager, node_network, node_disk, and the worker cleanup counters.
node-ctl: SSD headroom and its reconcile families.
net-gateway, volmgr, credmgr, snapshot-retention, node-runtime-core (behind host-runtime), spaced-host-server, template-mgr, build-mgr, and node-api-server.

The net gateway's readiness waits, which the gateway and sbx-mgr both record, go to the new pplx-space-sandbox-metrics (l40_api). The skill names it (plugin 0.2.51). The OTLP validation workload, which calls node-mgr's and sbx-mgr's helpers, becomes the metrics_workload binary of the new tools crate pplx-space-metrics-workload, and its README builds it from there.

Validation

Same checks and results as #1515, at e6993d22: the same 41 environmental failures. The dump is identical to main's; literals.py differs only by the new "host-runtime" cfg. Scripts are in #1515.
The README's cargo build of metrics_workload (--features otlp-metrics) builds the binary at this head. Not run:
the README's docker build step, any Kind smoke this change's paths select, and the OTLP workload run in
scripts/tests/observability/metrics.

Dependencies: no third-party package is added or removed. net-gateway now names the workspace metrics dependency
directly for its DNS recorder; it is the 0.24 release already in Cargo.lock through hickory-resolver. The lockfile
adds only workspace packages.

Severity and risk

Severity: does not apply (structural). Risk: compile-time only; roll back by reverting. External code that imports a moved path breaks.

Stack

metrics: move the Foundation, storage and shared families to their owners #1515. 2. This PR, based on metrics: move the Foundation, storage and shared families to their owners #1515. 3. metrics: move the control plane's families to their owners and delete pplx-space-metrics #1541, which deletes the crate.

AI assistance: Claude Code drafted the code, scripts and this text.

No actionable comments were generated in the recent review.

Walkthrough

Metric definitions and call sites move from the shared metrics crate into service-local modules. The change adds a shared sandbox metrics crate for gateway readiness and a standalone workload package. It updates dependencies, workspace membership, workload build instructions, and observability source references. Most metric arguments and service control flow remain unchanged. TCP proxy HTTP setup failures now also emit an upstream failure metric.

Possibly related PRs

perplexityai/SPACE#1541: Continues this migration, extends the new crate, and removes the legacy metrics crate.

Merge Risk: Minimal · up to e6993

The documentation concern is fixed, and no actionable merge-blocking issue remains after normal checks.

Security architecture risk: Low · up to e6993

The inspected changes preserve authorization and resource-cleanup behavior while moving telemetry to its owners. No introduced security weakness was established. Risk remains low rather than minimal because coverage of the broad migration and deployment validation is incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The dependency migration reaches privileged node-side services, but the inspected metric helpers observe outcomes rather than grant authority. Direct comparisons of wait-ready forwarding, gateway admission, and BYOK recording did not establish increased attacker-controlled scope or privileges.

Trust Boundaries and Controls

observed — The existing wait-ready boundary derives and overwrites forwarded policy server-side. Sandbox-manager authorizes the peer and restricts the node-API token exemption to trusted lifecycle calls without a supplied token; other calls retain token verification. These controls predate the PR and remain unchanged in the inspected comparison.

Resilience and Maintainability Implications

observed — The inspected gateway retains connection permits through serving, releases them on listener failure or completion, and preserves shutdown handling. Wait-ready replay continues to clone metadata, bound retries, and propagate terminal errors. Metric relocation does not change these failure-containment mechanisms.

Check name	Status	Explanation
Title check		The title describes the metric-family relocation and meets the required format.
Description Follows The Pr Template		The description contains all four required items. It states the change, validation and results, severity and risk, and AI assistance.
Bug Fixes Name A Regression Test		The PR moves metric families to their owners. The reviewed changes do not identify an application bug fix, so the regression-test requirement does not apply.
Weakened Safeguards Are Justified		The diff preserves the moved tests and assertions. The skill edit adds a crate example without weakening its guidance or changing review criteria.
Agent Tooling Runs No New Commands		The manifest changes only update versions. The skill change adds prose. The diff adds no agent-run commands or server configuration.
Public-Safe Content		The title, description, and diff contain no identified public-safety violations. The domain-like value in the diff is a Kubernetes label, not an internal hostname or URL.

CodeRabbit: Dismissed by CodeRabbit

johnlouie-pplx

Approving. The metric definitions now live with the services that emit them, while shared readiness timing stays in one place. I checked the moved definitions and callers against the base; metric names, types, units, tags, and cancellation behavior are preserved.

The pull request changed after this approval. CodeRabbit approves again after it reviews the current head.

Second of three changes that split pplx-space-metrics and delete it. The families the node-side services record move, unchanged, into a `metrics` module of the crate that records them: - sbx-mgr: `snapshot`, `sandbox::vm`, `sandbox::worker` (with the auto-lifecycle delete admission already there), `sandbox_eviction`, `stream_presence`, and its `reconcile` apply, network-policy and credential-pull families. - node-mgr: `byok`, `node_manager`, `node_network`, `node_disk`, and the worker cleanup counters it records (`sandbox_worker`). - node-ctl: `node_disk` (SSD headroom) and its `reconcile` families. - net-gateway (the `gateway` family, with the external `metrics` crate its Hickory DNS recorder uses), volmgr, credmgr, snapshot-retention, node-runtime-core (behind `host-runtime`, as its call site is), spaced-host-server (the spaced bridge), template-mgr and build-mgr (the template families each records; build-mgr-server uses build-mgr's). - node-api-server: `node_api` and its wait-ready policy counter. The net gateway's readiness waits, which the gateway and sbx-mgr both record, move to the new pplx-space-sandbox-metrics (l40_api), for families several services record, as `gateway_readiness`, with the spaced guest readiness wait built on the same `Wait`. The space-observability skill names it. The `metrics_workload` OTLP validation workload, which calls node-mgr's and sbx-mgr's helpers, becomes the `metrics_workload` binary of the new tools crate pplx-space-metrics-workload (behind its `otlp-metrics` feature), and scripts/tests/observability/metrics/README.md builds it from there. Metric names, tag keys, kinds and vocabulary values are unchanged: the dump of every emit site (with its enclosing function) and vocabulary arm is identical to main's, and the string literals on the removed and added lines of the Rust diff match except for the new `host-runtime` cfg string.
