The PBS poller's version-failure exit at monitor_pbs_pmg.go did not
set pollErr before returning, so even after fixing the defer-arg
capture in bf6261adc the deferred recordTaskResult still saw nil and
recorded the poll as a success. PMG's analogous path already sets
pollErr correctly. Mirror that here so the per-instance pollStatusMap,
the connections aggregator, and the circuit breaker all see PBS auth
and version failures as failures.
Add assertions to the existing PBS and PMG auth-failure tests that
the per-instance pollStatusMap entry has a zero LastSuccess and a
non-zero ConsecutiveFailures. The original tests covered downstream
state but not the recorder, which is why two distinct cases of this
class of bug went unnoticed.
The deferred recordTaskResult call was passing pollErr as a function
argument, so it captured the value at defer-time (always nil) instead
of the value at execution time. Result: the per-instance pollStatusMap
treated every poll as a success — LastSuccess was set to "now" on
every cycle, ConsecutiveFailures stayed at zero, and the circuit
breaker never opened, even when the staleness tracker (which used a
proper closure) recorded the same poll as a failure.
The connections aggregator derives state from PollStatus.LastSuccess,
so the Connections UI reported broken PVE/PBS/PMG instances as
"active / verified / healthy" while no data was ingested. Wrap the
recordTaskResult call in a defer closure so it reads the live pollErr
at execution time, matching the pollMetrics and stalenessTracker
defers immediately above.
Introduces GET /api/connections and POST /api/connections/probe as the
backend half of the one-ledger / one-editor connection redesign.
- GET /api/connections aggregates PVE/PBS/PMG/VMware/TrueNAS/agent rows
into a unified Connection shape with derived state (active, paused,
unauthorized, unreachable, stale, pending) computed from in-memory
scheduler health plus agent Host.LastSeen. No new persisted state.
- POST /api/connections/probe fingerprints a host across the five
supported products in parallel (2s dial + 1s read, 3s total, max 5
concurrent). Admin-gated (RequireAdmin + ScopeSettingsWrite) to block
unauthenticated SSRF against internal hosts.
- Disabled bool on PVEInstance/PBSInstance/PMGInstance (zero-value =
enabled, preserves existing nodes.json); pollers skip disabled
instances at client init, reconnect, and per-node iteration.
- NodeConfigRequest/Response gain Enabled; write path translates
*bool -> Disabled so omitted field leaves state untouched.
- ConnectionsAPI frontend client (list/probe) typed off the Go shape.
Contracts updated: api-contracts, monitoring, agent-lifecycle,
performance-and-scalability, storage-recovery. Proofs added:
contract_test.go JSON snapshot for Connection and ProbeResponse,
monitoring guardrails for the Disabled-skip behavior, and a vitest
mock-client test for ConnectionsAPI.
Frontend editor / drawer / table rewrite lands in a separate block.
