Clears the six dupl pairs in internal/monitoring:
- poll_providers.go: PVE/PBS/PMG listInstances / describeInstances /
connectionStatus closures collapse into generic sortedClientNames,
describeProviderInstances, and providerConnectionStatuses helpers; the
PBS/PMG adapters are now built by newPrefixedPollProvider from a
prefixedPollProviderSpec (prefix drives status keys, health keys, and
the fallback instance name).
- truenas_poller.go / vmware_poller.go: the Start scheduling loop
(double-start guard, stopped-channel handshake, sync+poll cadence)
moves to startPollerLoop, and the active-connection config policy
(enabled instances keyed by trimmed connection ID, defaults applied)
moves to loadActiveInstanceConfigs, both in the new
platform_poller_shared.go.
- monitor_polling_vm.go / monitor_polling_containers.go: traditional
polling now records guest series via the existing canonical
recordGuestMetric helper (io/network sentinels preserve the historical
cpu/memory/disk-only behavior on this path); the source-shape
guardrails in canonical_guardrails_test.go and
memory_source_catalog_test.go pin the new delegation.
- mock_metrics_history.go: native and TrueNAS disk seeding share one
seedDiskTelemetry closure.
Proof: new TestTrueNASPollerDoubleStartKeepsSingleLoop pins the shared
lifecycle loop; new TestSeedMockMetricsHistory_DiskTelemetryParityAcrossNativeAndTrueNAS
pins four-series parity for both disk sources. Contract Extension Points
name the shared wiring layer and poller scaffold.
Full internal/monitoring test suite passes.
Tighten v5-to-v6 upgrade safety, release installability, provider MSP mode handling, AI cost accounting, metrics flushing, and frontend guardrails for the v6.0.0 GA candidate.
