Full-Lifecycle IT Result

AlertingFullLifecycleIT — 5 steps, all PASS:

1. step1_seedLogAndEvaluate_createsFireInstance — LOG_PATTERN rule fires on ClickHouse-indexed log
2. step2_dispatchJob_deliversWebhook — WireMock HTTPS receives POST with X-Cameleer-Signature: sha256=...
3. step3_ack_transitionsToAcknowledged — REST POST /alerts/{id}/ack returns 200, DB state = ACKNOWLEDGED
4. step4_silence_suppressesSubsequentNotification — injected PENDING notification becomes FAILED "silenced", WireMock receives 0 additional calls
5. step5_deleteRule_nullifiesRuleIdButPreservesSnapshot — rule deleted, instances have rule_id = NULL, rule_snapshot still contains name

No flakiness observed across two full runs.

Pre-Existing Failure Confirmation

The full mvn clean verify run produced 69 failures + errors in 333 total tests. None are in alerting packages.

Pre-existing failing test classes (unrelated to Plan 02):

Class	Failures	Category
AgentSseControllerIT	4 timeouts + 3 errors	SSE timing, pre-existing
AgentRegistrationControllerIT	6 failures	JWT/bootstrap, pre-existing
AgentCommandControllerIT	1 failure + 3 errors	Commands, pre-existing
RegistrationSecurityIT	3 failures	Security, pre-existing
SecurityFilterIT	1 failure	JWT filter, pre-existing
SseSigningIT	2 failures	Ed25519 signing, pre-existing
JwtRefreshIT	4 failures	JWT, pre-existing
BootstrapTokenIT	2 failures	Bootstrap, pre-existing
ClickHouseStatsStoreIT	8 failures	CH stats, pre-existing
IngestionSchemaIT	3 errors	CH ingestion, pre-existing
ClickHouseChunkPipelineIT	1 error	CH pipeline, pre-existing
ClickHouseExecutionReadIT	1 failure	CH exec, pre-existing
DiagramLinkingIT	2 errors	CH diagrams, pre-existing
DiagramRenderControllerIT	4 errors	Controller, pre-existing
SearchControllerIT	4 failures + 9 errors	Search, pre-existing
BackpressureIT	2 failures	Ingestion, pre-existing
FlywayMigrationIT	1 failure	Shared container state, pre-existing
ConfigEnvIsolationIT	1 failure	Config, pre-existing
MetricsControllerIT	1 error	Metrics, pre-existing
ProtocolVersionIT	1 failure	Protocol, pre-existing
ForwardCompatIT	1 failure	Compat, pre-existing
ExecutionControllerIT	1 error	Exec, pre-existing
DetailControllerIT	1 error	Detail, pre-existing

These were confirmed pre-existing by running the same suite on feat/alerting-01-outbound-infra. They are caused by shared Testcontainer state, missing JWT secret in test profiles, SSE timing sensitivity, and ClickHouse ReplacingMergeTree projection incompatibility.

Known Deferrals

Plan 03 (UI phase)

• UI components for alerting (rule editor, inbox, silence manager, CMD-K integration, MustacheEditor)
• OpenAPI TypeScript regen (npm run generate-api:live) — deferred to start of Plan 03
• Rule promotion across environments (pure UI flow)

Architecture / data notes

• P95 metric fallback: RouteMetricEvaluator for P95_PROCESSING_MS falls back to mean because stats_1m_route does not store p95 (Camel's Micrometer does not emit p95 at the route level). A future agent-side metric addition would be required.
• CH projections on Testcontainer ClickHouse: alerting_projections.sql projections on executions (a ReplacingMergeTree) require SET deduplicate_merge_projection_mode='rebuild' session setting, which must be applied out-of-band in production. The ClickHouseSchemaInitializer logs these as non-fatal WARNs and continues — the evaluators work without the projections (full-scan fallback).
• Attribute-key regex validation: AlertRuleController validates ExchangeMatchCondition.filter.attributes keys against ^[a-zA-Z0-9._-]+$ at rule-save time. This is the only gate against JSON-extract SQL injection — do not remove or relax without a thorough security review.
• Performance tests (500 rules × 5 replicas via FOR UPDATE SKIP LOCKED) — deferred to a dedicated load-test phase.

Workarounds Hit During Implementation

1. Duplicate @MockBean errors: AbstractPostgresIT was updated during Phase 9 to centralise clickHouseSearchIndex and agentRegistryService mocks, but 14 subclasses still declared the same mocks locally. Fixed by removing the duplicates from all subclasses; clickHouseLogStore mock stays per-class because it is only needed in some tests.

2. WireMock HTTPS + TRUST_ALL: AlertingFullLifecycleIT uses WireMockConfiguration.options().httpDisabled(true).dynamicHttpsPort() with the outbound connection set to TRUST_ALL. The ApacheOutboundHttpClientFactory correctly bypasses hostname verification in TRUST_ALL mode, so WireMock's self-signed cert is accepted without extra config.

3. ClickHouse projections skipped non-fatally: Testcontainer ClickHouse 24.12 rejects ADD PROJECTION on ReplacingMergeTree without deduplicate_merge_projection_mode='rebuild'. The initializer was already hardened to log WARN and continue; AlertingProjectionsIT and evaluator ITs pass because the evaluators do plain WHERE queries that don't require projection hits.

Manual Smoke Script

Quick httpbin.org smoke test for webhook delivery (requires running server):

# 1. Create an outbound connection (admin token required)
TOKEN="<admin-jwt>"
CONN=$(curl -s -X POST http://localhost:8081/api/v1/admin/outbound-connections \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"httpbin-smoke","url":"https://httpbin.org/post","method":"POST","tlsTrustMode":"SYSTEM_DEFAULT","auth":{}}' | jq -r .id)
echo "Connection: $CONN"

# 2. Create a LOG_PATTERN rule referencing the connection
OP_TOKEN="<operator-jwt>"
ENV="dev"   # replace with your env slug
RULE=$(curl -s -X POST "http://localhost:8081/api/v1/environments/$ENV/alerts/rules" \
  -H "Authorization: Bearer $OP_TOKEN" \
  -H "Content-Type: application/json" \
  -d "{\"name\":\"smoke-test\",\"severity\":\"WARNING\",\"conditionKind\":\"LOG_PATTERN\",
       \"condition\":{\"kind\":\"LOG_PATTERN\",\"scope\":{},\"level\":\"ERROR\",\"pattern\":\"SmokeTest\",\"threshold\":0,\"windowSeconds\":300},
       \"webhooks\":[{\"outboundConnectionId\":\"$CONN\"}]}" | jq -r .id)
echo "Rule: $RULE"

# 3. POST a matching log
curl -s -X POST http://localhost:8081/api/v1/data/logs \
  -H "Authorization: Bearer <agent-jwt>" \
  -H "Content-Type: application/json" \
  -d '[{"timestamp":"'"$(date -u +%Y-%m-%dT%H:%M:%SZ)"'","level":"ERROR","logger":"com.example.Test","message":"SmokeTest fired","thread":"main","mdc":{}}]'

# 4. Trigger evaluation manually (or wait for next tick)
# Check alerts inbox:
curl -s "http://localhost:8081/api/v1/environments/$ENV/alerts" \
  -H "Authorization: Bearer $OP_TOKEN" | jq '.[].state'

Red Flags for Final Controller Pass

• The alert_rules.webhooks JSONB array stores WebhookBinding.id UUIDs that are NOT FK-constrained — if a rule is cloned or imported, binding IDs must be regenerated.
• InAppInboxQuery uses ? = ANY(target_user_ids) which requires the text[] cast to be consistent with how user IDs are stored (currently TEXT); any migration to UUID user IDs would need this query updated.
• AlertingMetrics gauge suppliers call jdbc.queryForObject(...) on every Prometheus scrape. At high scrape frequency (< 5s) this could produce noticeable DB load — consider bumping the Prometheus scrape_interval for alerting gauges to 30s in production.
• The PerKindCircuitBreaker is per-JVM (not distributed). In a multi-replica deployment, each replica has its own independent circuit breaker state — this is intentional (fail-fast per node) but means one slow ClickHouse node may open the circuit on one replica while others continue evaluating.
