Bundle C task M5-T7 — surface DefaultAuditPayloadFilter redactor
over-redactions as a Site Health metric so a misconfigured /
catastrophic regex shows up on /monitoring/health rather than
disappearing into a NoOp sink.
- SiteHealthReport: new 'AuditRedactionFailure' int field
(defaulted to 0 for back-compat with existing producers/tests).
- ISiteHealthCollector / SiteHealthCollector:
new IncrementAuditRedactionFailure() — per-interval atomic
counter with Interlocked, reset on CollectReport, mirroring
the M2 Bundle G SiteAuditWriteFailures pattern.
- HealthMetricsAuditRedactionFailureCounter: new bridge in
ScadaLink.AuditLog.Site that forwards IAuditRedactionFailureCounter
increments to ISiteHealthCollector — mirrors
HealthMetricsAuditWriteFailureCounter one-for-one.
- AddAuditLogHealthMetricsBridge: now ALSO Replaces the
NoOpAuditRedactionFailureCounter binding with the health-metrics
bridge, so a single AddAuditLogHealthMetricsBridge() call wires
both the M2 Bundle G write-failure counter and the M5 Bundle C
redaction-failure counter into the health report.
Site-side only for M5 — the filter also runs on CentralAuditWriter
and AuditLogIngestActor (where it just keeps the NoOp default), but
a central-side health-metric surface for AuditRedactionFailure is
deferred to M6 alongside the rest of the central health collector
work.
Tests:
- AuditRedactionFailureMetricTests (HealthMonitoring) covers the
SiteHealthCollector increment/report/reset shape (3 tests).
- HealthMetricsAuditRedactionFailureCounterTests (AuditLog) covers
the AuditLog → HealthMonitoring bridge (3 tests).
- Existing CountCapturingHealthCollector stub in
DeploymentManagerRedeployTests extended with the new no-op
interface method.
Verified: dotnet build clean, all 24 test projects green
(the only Failed at first ScadaLink.SiteRuntime.Tests run was the
known-flaky InstanceActorChildAttributeRaceTests; passes on re-run
in isolation and full suite, unrelated to these changes).
Bundle G of Audit Log #23 M2. Bridges the FallbackAuditWriter primary-
failure counter into the Site Health Monitoring report payload so a
sustained audit-write outage surfaces on /monitoring/health instead of
disappearing into a NoOp sink.
- SiteHealthReport: add SiteAuditWriteFailures (defaulted, additive).
- ISiteHealthCollector + SiteHealthCollector: new
IncrementSiteAuditWriteFailures() counter, per-interval reset
semantics matching ScriptErrorCount / DeadLetterCount.
- HealthMetricsAuditWriteFailureCounter: adapter forwarding
IAuditWriteFailureCounter.Increment() to the collector.
- AddAuditLogHealthMetricsBridge(): swaps the NoOp default
registration for the real bridge; called from
SiteServiceRegistration after AddSiteHealthMonitoring + AddAuditLog.
- Existing host-wiring test updated: site composition now resolves
HealthMetricsAuditWriteFailureCounter (not NoOp).
Tests: HealthMonitoring 60 -> 63 (3 new), AuditLog 56 -> 59 (3 new),
full solution green.
Add NodeStatus record, IClusterNodeProvider interface, and AkkaClusterNodeProvider
that queries Akka cluster membership for all site-role nodes. HealthReportSender
populates ClusterNodes before each report. UI shows a row per node with
hostname, Online/Offline badge, and Primary/Standby badge. Falls back to
single-node display if ClusterNodes is not populated.
New fields in SiteHealthReport: NodeHostname, DataConnectionEndpoints
(primary/secondary), DataConnectionTagQuality (good/bad/uncertain),
ParkedMessageCount. New collector methods to populate them.
Health dashboard redesigned to match mockup: Nodes | Data Connections
(with per-connection tag quality) | Instances + S&F Buffers | Error
Counts + Parked Messages. Site names resolved from repository.
Both nodes of a site cluster were sending health reports. The standby
node (without the DeploymentManager singleton) reported 0 instances and
no connections, overwriting the active node's data in the aggregator.
Added IsActiveNode flag to ISiteHealthCollector, set by
DeploymentManagerActor on PreStart/PostStop. HealthReportSender skips
sending when the node is not active. Also ensured EnsureDclConnections
is called during startup batch creation so data connections survive
container restarts.
Wired ISiteHealthCollector calls for script errors (ScriptExecutionActor),
alarm eval errors (AlarmActor), dead letters (DeadLetterMonitorActor), and
S&F buffer depth placeholder. Added instance count tracking (deployed/
enabled/disabled) to SiteHealthReport via DeploymentManagerActor. Updated
Health Dashboard UI to show instance counts per site. All metrics flow
through the existing health report pipeline via ClusterClient.
