AuditInboundCeilingHits counter: new IAuditInboundCeilingHitsCounter interface + NoOpAuditInboundCeilingHitsCounter default; AuditCentralHealthSnapshot implements the interface (Interlocked field, thread-safe) and exposes AuditInboundCeilingHits on IAuditCentralHealthSnapshot; AddAuditLog registers the NoOp default, AddAuditLogCentralMaintenance forwards to the snapshot; AuditWriteMiddleware accepts the counter as an optional ctor arg and increments it once per request where either the request or response body hit the cap. 3. Per-method SkipBodyCapture opt-out: adds SkipBodyCapture bool to PerTargetRedactionOverride; AuditWriteMiddleware consults the per-target override map at the start of InvokeAsync (before EnableBuffering) and, when set, skips body read + capture entirely — the audit row still emits with headers/metadata but null RequestSummary/ResponseSummary; truncation flags are also cleared so the ceiling-hits counter is not bumped for opted-out methods. --- .../Central/AuditCentralHealthSnapshot.cs | 12 +- .../Central/IAuditCentralHealthSnapshot.cs | 11 + .../IAuditInboundCeilingHitsCounter.cs | 24 + .../NoOpAuditInboundCeilingHitsCounter.cs | 13 + .../PerTargetRedactionOverride.cs | 11 + .../ServiceCollectionExtensions.cs | 13 + .../Middleware/AuditWriteMiddleware.cs | 78 +++- .../Central/CentralAuditWriteFailuresTests.cs | 64 +++ .../Middleware/AuditWriteMiddlewareTests.cs | 425 ++++++++++++++++++ 9 files changed, 643 insertions(+), 8 deletions(-) create mode 100644 src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/IAuditInboundCeilingHitsCounter.cs create mode 100644 src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/NoOpAuditInboundCeilingHitsCounter.cs diff --git a/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/AuditCentralHealthSnapshot.cs b/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/AuditCentralHealthSnapshot.cs index 396a80f5..68b6a814 100644 --- a/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/AuditCentralHealthSnapshot.cs +++ b/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/AuditCentralHealthSnapshot.cs @@ -39,10 +39,12 @@ namespace ZB.MOM.WW.ScadaBridge.AuditLog.Central; public sealed class AuditCentralHealthSnapshot : IAuditCentralHealthSnapshot, ICentralAuditWriteFailureCounter, - IAuditRedactionFailureCounter + IAuditRedactionFailureCounter, + IAuditInboundCeilingHitsCounter { private int _centralAuditWriteFailures; private int _auditRedactionFailure; + private int _auditInboundCeilingHits; private readonly ConcurrentDictionary _stalled = new(); /// @@ -53,6 +55,10 @@ public sealed class AuditCentralHealthSnapshot public int AuditRedactionFailure => Interlocked.CompareExchange(ref _auditRedactionFailure, 0, 0); + /// + public int AuditInboundCeilingHits => + Interlocked.CompareExchange(ref _auditInboundCeilingHits, 0, 0); + /// public IReadOnlyDictionary SiteAuditTelemetryStalled => new Dictionary(_stalled); @@ -78,4 +84,8 @@ public sealed class AuditCentralHealthSnapshot /// void IAuditRedactionFailureCounter.Increment() => Interlocked.Increment(ref _auditRedactionFailure); + + /// + void IAuditInboundCeilingHitsCounter.Increment() => + Interlocked.Increment(ref _auditInboundCeilingHits); } diff --git a/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/IAuditCentralHealthSnapshot.cs b/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/IAuditCentralHealthSnapshot.cs index 357b67ae..89bb4675 100644 --- a/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/IAuditCentralHealthSnapshot.cs +++ b/src/ZB.MOM.WW.ScadaBridge.AuditLog/Central/IAuditCentralHealthSnapshot.cs @@ -50,6 +50,17 @@ public interface IAuditCentralHealthSnapshot /// int AuditRedactionFailure { get; } + /// + /// Count of inbound request/response body truncations at the + /// + /// ceiling since process start.

A one-time CLI command sets +these to a configurable sentinel: + +``` +scadabridge audit backfill-source-node --before [--sentinel unknown] [--batch 5000] +``` + +The default sentinel is `"unknown"`. The true node-of-origin for pre-feature rows +is **unknowable** retroactively — the emitting node is long gone from the telemetry +pipeline. The sentinel makes that explicit rather than leaving the column NULL +(which the Audit Log UI's Node filter already treats as "unresolved", but which +an operator might mistake for a data-quality bug). + +The backfill runs via `POST /api/audit/backfill-source-node` (Admin role required) +on the maintenance/purge path, NOT the append-only `scadabridge_audit_writer` role. +It is idempotent and can be re-run safely. + +### `ExecutionId` and `ParentExecutionId` — cannot be backfilled + +`ExecutionId` and `ParentExecutionId` are **PERSISTED COMPUTED columns** derived +from `DetailsJson`. They were introduced in the same feature window as the column +itself but their value comes from the JSON payload that was written at ingest time. + +The AuditLog append-only invariant **forbids mutating `DetailsJson`** — rows may +only be inserted, never updated. Because backfilling the computed values would +require rewriting the underlying `DetailsJson`, it is impossible under the +append-only contract. Pre-feature rows carry `NULL` in both columns permanently. + +This is a documented limitation, not a defect. The NULL values are visible in the +Audit Log UI's execution-tree drilldown (rows with no `ExecutionId` appear as +orphaned entries) and in the CLI's `audit tree` output. + ## Dependencies - **[Commons (#16)](Component-Commons.md)** — `AuditEvent`, `IAuditWriter` / diff --git a/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs b/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs new file mode 100644 index 00000000..e59e21c1 --- /dev/null +++ b/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs @@ -0,0 +1,113 @@ +using System.Text; +using System.Text.Json; + +namespace ZB.MOM.WW.ScadaBridge.CLI.Commands; + +/// +/// Arguments for an audit backfill-source-node invocation. +/// +public sealed class AuditBackfillSourceNodeArgs +{ + /// + /// Value written into SourceNode for NULL rows (default "unknown"). + /// + public string Sentinel { get; set; } = "unknown"; + + /// + /// Only rows with OccurredAtUtc strictly before this UTC datetime are + /// eligible.
