A Server's page now shows what the Server uses. Resources has meters, charts and a disk breakdown, all read live from the Server. Running here lists each Service with the CPU and memory it uses on that Server now.

What a user sees

Resources opens with three meters: CPU as a percent, Memory as used / total, and Disk as used / total. Memory and Disk show their percent beside the title. A meter turns amber at 85%.
The meters and the CPU and Memory header values always show the last few minutes, whatever range is picked. A meter whose last reading is older than that reads –.
Three charts follow on one time axis: CPU, Memory with a dashed Total line, and Network. Each interface gets its own color, with out solid and in dashed. Server charts carry no deploy or event markers.
The range is one of 1h, 6h, 1d, 7d and 30d. While a new range loads, the charts stay up.
The Disk card splits used space into the parts the Server names (Volumes, Mirrors, Logs and metrics, Other), then Free. Used space the Server didn't attribute shows as one neutral Used segment. It is never labelled Other. The bar always covers used / total.
A stretch the Server didn't measure is hatched Not measured. With nothing in range, each chart and the disk card read No readings, and the meters read – with an empty track that screen readers skip. Missing data never draws as zero.
A Server on an older daemon reads Upgrade syd-1 to see its metrics. A Server whose read fails, or that reports itself offline, reads fra-1 didn’t answer. While the Runtime Watch shows a Server offline, the page leaves Resources out and reads nothing: the Can’t reach fra-2 alert already says so.
Running here lists up to five Services inline. Each row shows its name and namespace, plus usage like 0.24 vCPU · 318 MB, or – when its read has no recent reading for this Server. Rows refresh when the page opens or regains focus, not on a timer. Past five, All 12 services opens the existing sheet, which has the same rows and the filter. While the Server is offline, rows read Still on fra-1 or Down as before.
What's using this Server is gone.

Cost of the now-values

Core's metrics subject is a Service or a Machine. It has no "this Service on this Machine" scope, so each row reads its Service across every Server and keeps this Server's share. One row costs one Cloud read, and that read asks all M Servers. The page reads at most five rows, and the sheet reads only while it is open. With three Servers, opening the page costs two host reads (the range and the last five minutes) plus five Service reads, which is 17 Server reads. Rows read again only on focus. A by-Service scope on the Machine read in core would make this one read. That is the follow-up if the fan-out shows up in daemon load.

Changes

readRuntimeServiceMetricsServerFn and runtimeServiceMetricsQueryOptions read a runtime Service by namespace and name. They are registered as on-demand remote data next to the other metrics reads.
servers/-components/server-resources.tsx holds the section. server-usage.ts holds the pure parts: the disk segments and one Server's fresh share of a Service. The meters and header values read serverMetricsQueryOptions over the last five minutes through serverNow, which uses the exported freshLast.
$serverId.tsx puts Resources above Running here and gives Running here inline rows.
It reuses PR 2's MetricChart and metric-chart-data.ts unchanged. It carries PR 5's metric-meter.tsx unchanged. The page meters are full-width cards, not that compact list meter.
runtimeServiceMetricsQueryOptions has no refetch interval.
.agents/skills/verify-dashboard/SKILL.md describes the four fake Servers, including ams-1 (4444…).
docs/user/servers/manage-servers.md describes both sections and adds server-resources.png and server-running-here.png. server-page.png, used by builds/where-builds-run.md, is reshot to show the current Services, Builds and Danger sections.

Testing

server-usage.test.ts covers the disk segments with a full breakdown, with none, with the pool unmeasured (1.8 TB total, 410 used, 38 logs and metrics, so a neutral 372 Used), and with logs and metrics unmeasured (a neutral 100 Used). It covers that a row takes this Server's share and not the sum, and that a stale row reads nothing.
server-now.test.ts covers freshness for the meters.
metrics.verify-fixture.test.ts covers the gap and the no-readings Server.
data-boundaries.static.test.ts covers the new on-demand read.
pnpm typecheck and oxlint on the changed folders pass.
Screenshots come from FAKE_SERVERS=1 PLOYZ_VERIFY_METRICS=1 scripts/verify/up.sh.

Screenshots

fra-1, normal. The disk breakdown's Other is the Server's own Other, not a remainder.

fra-1, Running here.

fra-1 at 30d. The meters stay on the last few minutes.

syd-1, needs an upgrade.

fra-2, offline. Resources is left out under the Can’t reach fra-2 alert.

ams-1, answered with no readings. Meters read – and the charts read No readings.

The fixture has no Server with an unattributed remainder or more than one interface, so the neutral Used segment and per-interface colors are covered by unit tests and code only.

📝 Summary

Summary by CodeRabbit

New Features
- Server detail pages now show CPU, memory, network, and disk metrics, with selectable history ranges and current readings when available.
- “Running here” rows show per-service CPU and memory usage. Up to five services appear inline; larger lists link to a searchable full list.
- Server resource views distinguish unavailable, stale, and offline readings.
Documentation
- Updated the server management guide to describe the resource metrics and service usage displays.

The server detail page adds resource charts and current usage, plus CPU and memory readings for services running on a server. The change adds a runtime-service metrics read path and freshness checks, updates verification fixtures, tests, and server documentation.

Changes: Server detail metrics

Layer / File(s)	Summary
Runtime-service metrics read path `dashboard/src/modules/metrics/metrics.ts`, `dashboard/src/modules/metrics/metrics.server.ts`, `dashboard/src/modules/metrics/metrics.functions.ts`, `dashboard/src/modules/metrics/metrics.queries.ts`, `dashboard/src/collections/data-boundaries.static.test.ts`	Adds a validated runtime-service metrics input, an access-checked history reader, a GET server function, and query options keyed by organization, service, and time range.
Freshness and usage calculations `dashboard/src/routes/_protected/cloud/$organizationSlug/_org/~/servers/-components/server-now.ts`, `.../server-now.test.ts`, `.../server-meters.tsx`, `.../server-usage.ts`, `.../server-usage.test.ts`	`serverNow` now accounts for query age when checking freshness. New helpers calculate service usage for one server and produce disk breakdown segments.
Server Resources panel `dashboard/src/routes/_protected/cloud/$organizationSlug/_org/~/servers/-components/server-resources.tsx`, `.../server-resources.test.tsx`	Adds selectable historical ranges and current CPU, memory, network, and disk displays. Tests cover fresh values, failed refreshes, and stale cached reads.
Server detail and service rows `dashboard/src/routes/_protected/cloud/$organizationSlug/_org/~/servers/$serverId.tsx`, `.../service-usage.tsx`, `.../service-usage.test.tsx`, `dashboard/src/modules/metrics/metrics.verify-fixture.ts`, `.../metrics.verify-fixture.test.ts`, `dashboard/src/modules/runtime/runtime-watch.verify-fixture.ts`, `.agents/skills/verify-dashboard/SKILL.md`, `docs/user/servers/manage-servers.md`	The server page embeds Resources and shows up to five service rows, with a filtered list for additional services. Fixtures add no-reading and service/container states; tests and documentation cover the updated displays.

Merge Risk: 🔵 Low · up to 51035

Service usage on a page left open can appear current after its reading expires. This is a bounded display issue that should be fixed or accepted before merging.

Security architecture risk: 🔵 Low · up to 51035

The new read preserves authentication and organization-wide access checks. It can retrieve service history across the authorized organization’s servers, but no cross-organization access or increased privileges were established. Production exposure and some history-retention and cancellation behavior remain unverified.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The new endpoint expands selectable runtime-service identities beyond current configuration lookup. Its supported scope is matching service history across the authorized organization’s connected machines, not merely the server displayed by the page. Retention after service removal remains unresolved.

Trust Boundaries and Controls

observed — Caller-controlled organization and service identifiers pass through actor resolution and organization authorization. The returned organization ID selects downstream runtime connections; namespace/name cannot select a different organization’s runtime session.

Resilience and Maintainability Implications

observed — The new caller inherits the unchanged scoped read lifecycle. Each runtime session has independent registration and finalization, and pairing cancellation is scoped by organization and generation. Client closure provides cancellation containment, but exact transport-abort timing for metricHistory is not established.

_{_{P2 Badge}} Record the non-polling metrics freshness policy

This new factory intentionally has no refetchInterval, but the modules/metrics/metrics.queries.ts entry in data-sources.ts still says Service and Server metrics in this file are polled every minute. That makes the registry's reviewed freshness contract false for runtime-Service reads; update the registry to distinguish these focus-refreshed, non-polling queries.

_{_{P1 Badge}} Preload the always-visible server metrics

These reads are not on demand: every non-offline server page mounts ServerResources and up to five ServiceUsage rows immediately. Exempting both factories here means cold SSR and client navigation render a Resources skeleton and empty usage cells, then start up to seven reads only after mount, contrary to the route-data contract; start the visible reads from this route with streamRemote/prefetchRemote, while retaining an on-demand exception only for rows mounted when the sheet opens.

Re-render service usage when its sample expires.

ServiceUsage checks freshness only during render. serviceUsageOn returns null for stale samples, but the runtime service query has no timer and the component has no clock-based rerender. An open row can therefore keep displaying an expired value instead of –.

Add a local expiry timeout. Do not add query polling.

_{_{P2 Badge}} Preserve the timestamp for placeholder charts

When a range toggle changes the query key, TanStack Query v5 exposes the previous payload as placeholder data but the new pending result's dataUpdatedAt is 0. Passing that value as answeredAt makes resolveRange({ from: range, to: "now" }, 0) produce an epoch-zero window, so onGrid finds none of the retained points and the charts flash “No readings” instead of staying visible while the new range loads. Preserve the previous response timestamp/window together with its placeholder data.

_{_{P2 Badge}} Reset retained metrics when switching servers

When ServerSwitcher navigates between two non-offline servers, this route component remains mounted and the query key changes to the new machine ID, so keepPreviousData supplies the previous server's response. Because its availability is immediately rendered with the current server.name, switching from an outdated syd-1 to a healthy fra-1, for example, temporarily shows “Upgrade fra-1 to see its metrics” until the new request completes. Retain placeholder data only for range changes on the same machine, or remount/reset this observer when the server ID changes.
