- Created features/microstructure.rs (skeleton)
- Created features/statistical.rs (skeleton)
Wave 3: Implement dual API (streaming + batch)
- Streaming API: RSI, EMA, MACD, BollingerBands, ATR, ADX (stateful calculators)
- Batch API: rsi_batch, ema_batch, macd_batch, bollinger_batch, atr_batch, adx_batch
- Zero-cost abstraction: No runtime performance degradation
Wave 4: Integration
- Updated common/src/lib.rs: Export features module + 12 public types/functions
- Updated ml/src/features/extraction.rs: [f64; 256] → [f64; 225], use common::features
- Updated ml/src/features/unified.rs: FeatureVector → [f64; 225]
- Updated common/src/ml_strategy.rs: Added 7 indicator calculators, extended to 225 features
- Fixed 24 test assertions across 7 files (30/256 → 225)

# AGENT WIRE-20: Prometheus Wave D Alerts Configuration Report
|
||
|
||
**Agent**: WIRE-20
|
||
**Mission**: Verify Prometheus alerts for regime flip-flopping, false positives, NaN/Inf
|
||
**Status**: ⚠️ PARTIALLY COMPLETE - Alert rules defined, metrics NOT exported
|
||
**Priority**: LOW - Monitoring infrastructure, not trading logic
|
||
**Date**: 2025-10-19
|
||
**Agent Lineage**: Agent M1 (created wave_d_alerts.yml) → Agent WIRE-20 (validation)
|
||
|
||
---
|
||
|
||
## Executive Summary
|
||
|
||
**CRITICAL FINDING**: Alert rules file exists and is well-structured, but **NONE of the Wave D metrics are currently exported** by any service. The alerts will NOT fire because the underlying Prometheus metrics do not exist.
|
||
|
||
### Alert Validation Results
|
||
|
||
| Check | Status | Details |
|
||
|---|---|---|
|
||
| Alert rules file exists | ✅ PASS | `/home/jgrusewski/Work/foxhunt/config/prometheus/rules/wave_d_alerts.yml` |
|
||
| Alert syntax valid | ⚠️ UNKNOWN | `promtool` not installed, unable to validate YAML syntax |
|
||
| Metrics match exports | ❌ FAIL | **Zero Wave D metrics exported** (0/10 required metrics) |
|
||
| Thresholds production-ready | ✅ PASS | Thresholds are reasonable and well-calibrated |
|
||
| Alert routing configured | ✅ PASS | Alertmanager production config exists with routing |
|
||
|
||
**Overall Status**: 🔴 **NOT OPERATIONAL** - Alert rules exist but will never fire due to missing metrics.

|
||
|
||
## 2. Critical Finding: Missing Metrics Exports
|
||
|
||
### Required Metrics (From Alert Rules)
|
||
|
||
The alert rules expect the following 10 Prometheus metrics to be exported:
|
||
|
||
1. `regime_transitions_total` (counter) - Total regime transitions
|
||
2. `regime_detections_total` (counter) - Total regime detections
|
||
3. `regime_detection_errors_total` (counter) - Regime detection errors
|
||
4. `regime_states_count` (gauge) - Current regime state counts by type
|
||
5. `wave_d_features_nan_count` (gauge) - NaN values in Wave D features
|
||
6. `wave_d_features_inf_count` (gauge) - Inf values in Wave D features
|
||
7. `wave_d_feature_extraction_duration_seconds` (histogram) - Feature extraction latency
|
||
8. `process_resident_memory_bytes` (gauge) - RSS memory usage (standard metric)
|
||
9. `up{job="foxhunt_services"}` (gauge) - Service availability (standard metric)
|
||
10. `postgres_stat_user_tables_n_tup_ins{relname="regime_states"}` (gauge) - DB row counts (PostgreSQL exporter)
|
||
|
||
### Actual Metrics Exported
|
||
|
||
**Search Result**: **ZERO Wave D-specific metrics found** in the codebase.
|
||
|
||
```bash
|
||
# Search command executed:
|
||
grep -r "regime_transitions_total|regime_detections_total|regime_detection_errors|wave_d_features_nan|wave_d_features_inf" **/*.rs
|
||
|
||
# Result: No matches found
|
||
```
|
||
|
||
**Analysis**:
|
||
- The `ml` crate has Prometheus as a dependency (`prometheus.workspace = true`)
|
||
- No `register_counter!()` or `register_gauge!()` calls for Wave D metrics exist
|
||
- The regime detection modules (`ml/src/regime/*.rs`) do NOT export Prometheus metrics
|
||
- The feature extraction modules (`ml/src/features/regime_*.rs`) do NOT export Prometheus metrics
|
||
|
||
### Impact
|
||
|
||
🔴 **ALL 9 WAVE D ALERTS WILL NEVER FIRE** because the underlying metrics do not exist.
|
||
|
||
The alert rules are correctly structured, but Prometheus will evaluate them as:
|
||
- `regime_transitions_total` → **undefined** → alert condition cannot be evaluated
|
||
- `wave_d_features_nan_count` → **undefined** → alert condition cannot be evaluated
|
||
- All other Wave D metrics → **undefined** → alerts inactive
|
||
|
||

|
||
|
||
## 3. Prometheus Configuration Analysis
|
||
|
||
### Prometheus Server Configuration
|
||
|
||
**File**: `/home/jgrusewski/Work/foxhunt/config/prometheus/prometheus.yml`
|
||
|
||
**Scrape Targets**:
|
||
```yaml
|
||
scrape_configs:
|
||
- job_name: 'api_gateway'
|
||
targets: ['api_gateway:9091']
|
||
scrape_interval: 5s
|
||
|
||
- job_name: 'trading_service'
|
||
targets: ['trading_service:9092']
|
||
scrape_interval: 5s
|
||
|
||
- job_name: 'backtesting_service'
|
||
targets: ['backtesting_service:9093']
|
||
scrape_interval: 10s
|
||
|
||
- job_name: 'ml_training_service'
|
||
targets: ['ml_training_service:9094']
|
||
scrape_interval: 15s
|
||
|
||
- job_name: 'postgres_exporter'
|
||
targets: ['foxhunt-postgres-exporter:9187']
|
||
scrape_interval: 30s
|
||
```
|
||
|
||
**Rule Files**:
|
||
```yaml
|
||
rule_files:
|
||
- "rules/*.yml"
|
||
```
|
||
|
||
✅ **Correctly configured** to load Wave D alerts from `rules/wave_d_alerts.yml`.
|
||
|
||
### Alertmanager Configuration
|
||
|
||
**File**: `/home/jgrusewski/Work/foxhunt/config/prometheus/alertmanager-production.yml`
|
||
|
||
**Key Features**:
|
||
- ✅ Slack integration configured (webhooks)
|
||
- ✅ Email alerts for critical issues (SMTP)
|
||
- ✅ Hierarchical routing by severity and component
|
||
- ✅ Inhibition rules to suppress redundant alerts
|
||
- ✅ Dedicated channels for different alert types:
|
||
- `#foxhunt-critical-latency`
|
||
- `#foxhunt-critical-outages`
|
||
- `#foxhunt-critical-memory`
|
||
- `#foxhunt-critical-risk`
|
||
- `#foxhunt-critical-trading`
|
||
- `#foxhunt-warnings-ml`
|
||
|
||
**Routing Logic**:
|
||
- Critical alerts: 0-10s group wait, 30s-2m group interval, 5-30m repeat
|
||
- Warning alerts: 30s-1m group wait, 5-10m group interval, 2-6h repeat
|
||
|
||
✅ **Production-ready routing** with appropriate escalation policies.
|

|
||
|
||
## 4. Alert Threshold Analysis
|
||
|
||
### Flip-Flopping Threshold: 50 transitions/hour
|
||
|
||
**Assessment**: ✅ **REASONABLE**
|
||
|
||
- **Target**: 5-10 transitions/day (from CLAUDE.md)
|
||
- **Alert threshold**: >50 transitions/hour = 1,200 transitions/day
|
||
- **Ratio**: 120-240x above target
|
||
- **Verdict**: Appropriate safety margin. Only fires on severe flip-flopping.
|
||
|
||
**Example Scenarios**:
|
||
- Normal: 8 transitions/day → NO ALERT
|
||
- High volatility: 30 transitions/day → NO ALERT
|
||
- Unstable detection: 1,200 transitions/day → ALERT FIRES
|
||
|
||
### False Positive Threshold: 80% error rate
|
||
|
||
**Assessment**: ✅ **REASONABLE**
|
||
|
||
- **Target**: <20% error rate (from alert rules)
|
||
- **Warning threshold**: 20-80% error rate (WaveDDetectionErrorsModerate)
|
||
- **Critical threshold**: >80% error rate (WaveDFalsePositives)
|
||
- **Verdict**: Two-tier alerting (warning → critical) provides early detection and escalation.
|
||
|
||
**Example Scenarios**:
|
||
- Excellent: 5% error rate → NO ALERT
|
||
- Acceptable: 18% error rate → NO ALERT
|
||
- Degraded: 45% error rate → WARNING (monitor trend)
|
||
- Failed: 85% error rate → CRITICAL (Level 1 rollback)
|
||
|
||
### Data Corruption Threshold: ANY NaN/Inf
|
||
|
||
**Assessment**: ✅ **CORRECT (Zero Tolerance)**
|
||
|
||
- **Threshold**: `> 0` (any NaN/Inf triggers Level 3 rollback)
|
||
- **Duration**: 1 minute (fast response)
|
||
- **Verdict**: Correct zero-tolerance policy for data integrity.
|
||
|
||
NaN/Inf values in features are **catastrophic**:
|
||
- Propagate through ML models (garbage in, garbage out)
|
||
- Cause unpredictable trading behavior
|
||
- May indicate feature extraction bugs or data provider corruption
|
||
|
||
**Immediate Level 3 rollback is justified**.
|
||
|
||
### Latency Threshold: P99 > 2ms
|
||
|
||
**Assessment**: ✅ **REASONABLE**
|
||
|
||
- **Target**: <1ms per bar (from WAVE_D_PHASE_6_TECHNICAL_DEBT_CLEANUP_COMPLETE.md)
|
||
- **Alert threshold**: >2ms P99 (2x target)
|
||
- **Duration**: 15 minutes (allow temporary spikes)
|
||
- **Verdict**: 2x safety margin with sufficient observation window.
|
||
|
||
**Example Scenarios**:
|
||
- Normal: P99 = 500μs → NO ALERT
|
||
- Spike: P99 = 1.8ms for 5 min → NO ALERT (transient)
|
||
- Degradation: P99 = 2.5ms for 20 min → ALERT FIRES (Level 1 rollback)
|
||
|
||
### Memory Growth Threshold: 20%/hour
|
||
|
||
**Assessment**: ✅ **REASONABLE**
|
||
|
||
- **Threshold**: RSS growth >20%/hour
|
||
- **Duration**: 1 hour (confirm leak, not warmup)
|
||
- **Verdict**: Appropriate for leak detection with low false positive rate.
|
||
|
||
**Example Scenarios**:
|
||
- Warmup: RSS +15% in first hour, then stable → NO ALERT
|
||
- Cache growth: RSS +5%/hour sustained → NO ALERT
|
||
- Memory leak: RSS +25%/hour for 2 hours → ALERT FIRES
|
||
|
||
---
|
||
|
||
## 5. Alert Routing Validation
|
||
|
||
### Prometheus → Alertmanager Integration
|
||
|
||
**Prometheus Config**:
|
||
```yaml
|
||
# Expected Alertmanager endpoint (from standard Prometheus setup)
|
||
alerting:
|
||
alertmanagers:
|
||
- static_configs:
|
||
- targets: ['alertmanager:9093']
|
||
```
|
||
|
||
⚠️ **NOT FOUND** in `/home/jgrusewski/Work/foxhunt/config/prometheus/prometheus.yml`
|
||
|
||
**Impact**: Prometheus may not be configured to send alerts to Alertmanager. Need to verify:
|
||
```yaml
|
||
alerting:
|
||
alertmanagers:
|
||
- static_configs:
|
||
- targets: ['localhost:9093']
|
||
```
|
||
|
||
### Alertmanager Receivers
|
||
|
||
✅ **CONFIGURED** for all Wave D alert types:
|
||
|
||
| Alert | Severity | Receiver | Channels |
|
||
|---|---|---|---|
|
||
| WaveDFlipFlopping | critical | critical-generic | Slack, Webhook |
|
||
| WaveDFalsePositives | critical | critical-generic | Slack, Webhook |
|
||
| WaveDDataCorruption | critical | critical-generic | Slack, Webhook |
|
||
| FoxhuntSystemDown | critical | critical-service-down | Slack, Email, Webhook |
|
||
| WaveDLatencyDegradation | warning | warning-generic | Slack |
|
||
| WaveDMemoryLeak | warning | warning-resources | Slack |
|
||
| WaveDRegimeCoverageHigh | warning | warning-ml | Slack |
|
||
| WaveDRegimeTransitionRateLow | warning | warning-ml | Slack |
|
||
| WaveDDetectionErrorsModerate | warning | warning-generic | Slack |
|
||
|
||
**Notification Channels**:
|
||
- Slack: 10+ dedicated channels (#foxhunt-critical-*, #foxhunt-warnings-*)
|
||
- Email: `oncall@foxhunt.local` for critical service down
|
||
- Webhook: `http://localhost:5001/*` for custom integrations
|
||
|
||
---
|
||
|
||
## 6. Missing Components Analysis
|
||
|
||
### What Exists ✅
|
||
|
||
1. **Alert Rules File**: `wave_d_alerts.yml` (18.7 KB, 9 rules)
|
||
2. **Prometheus Config**: Scrape targets for all 5 services
|
||
3. **Alertmanager Config**: Production routing with Slack/Email/Webhook
|
||
4. **Rule Loading**: `rule_files: - "rules/*.yml"` correctly configured
|
||
5. **Alert Thresholds**: Well-calibrated and production-ready
|
||
|
||
### What's Missing ❌
|
||
|
||
1. **Metrics Exports**: **ZERO Wave D metrics** exported by any service
|
||
2. **Alertmanager Integration**: Prometheus `alerting` section not visible in config
|
||
3. **Syntax Validation**: `promtool` not installed, cannot verify YAML syntax
|
||
4. **Testing Framework**: No alert unit tests (`.test.yml` files)
|
||
5. **Documentation**: No runbook links (URLs reference non-existent GitHub repo)
|
||
|
||
### Critical Gap: Metrics Implementation
|
||
|
||
**Required Actions** to make alerts operational:
|
||
|
||
1. **Implement Prometheus metrics in `ml` crate**:
|
||
```rust
|
||
// ml/src/regime/metrics.rs (NEW FILE)
|
||
use prometheus::{register_counter, register_gauge, register_histogram, Counter, Gauge, Histogram};
|
||
|
||
lazy_static! {
|
||
pub static ref REGIME_TRANSITIONS_TOTAL: Counter = register_counter!(
|
||
"regime_transitions_total",
|
||
"Total number of regime transitions"
|
||
).unwrap();
|
||
|
||
pub static ref REGIME_DETECTIONS_TOTAL: Counter = register_counter!(
|
||
"regime_detections_total",
|
||
"Total number of regime detections"
|
||
).unwrap();
|
||
|
||
pub static ref REGIME_DETECTION_ERRORS_TOTAL: Counter = register_counter!(
|
||
"regime_detection_errors_total",
|
||
"Total number of regime detection errors"
|
||
).unwrap();
|
||
|
||
pub static ref REGIME_STATES_COUNT: GaugeVec = register_gauge_vec!(
|
||
"regime_states_count",
|
||
"Current regime state counts by type",
|
||
&["regime"]
|
||
).unwrap();
|
||
|
||
pub static ref WAVE_D_FEATURES_NAN_COUNT: Gauge = register_gauge!(
|
||
"wave_d_features_nan_count",
|
||
"Number of NaN values in Wave D features"
|
||
).unwrap();
|
||
|
||
pub static ref WAVE_D_FEATURES_INF_COUNT: Gauge = register_gauge!(
|
||
"wave_d_features_inf_count",
|
||
"Number of Inf values in Wave D features"
|
||
).unwrap();
|
||
|
||
pub static ref WAVE_D_FEATURE_EXTRACTION_DURATION: Histogram = register_histogram!(
|
||
"wave_d_feature_extraction_duration_seconds",
|
||
"Wave D feature extraction latency"
|
||
).unwrap();
|
||
}
|
||
```
|
||
|
||
2. **Instrument regime detection code**:
|
||
```rust
|
||
// ml/src/regime/cusum.rs
|
||
use super::metrics::*;
|
||
|
||
impl CUSUMDetector {
|
||
pub fn detect_changepoint(&mut self, value: f64) -> Result<bool> {
|
||
REGIME_DETECTIONS_TOTAL.inc();
|
||
|
||
match self.internal_detect(value) {
|
||
Ok(is_changepoint) => {
|
||
if is_changepoint {
|
||
REGIME_TRANSITIONS_TOTAL.inc();
|
||
}
|
||
Ok(is_changepoint)
|
||
}
|
||
Err(e) => {
|
||
REGIME_DETECTION_ERRORS_TOTAL.inc();
|
||
Err(e)
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
3. **Instrument feature extraction**:
|
||
```rust
|
||
// ml/src/features/regime_cusum.rs
|
||
use crate::regime::metrics::*;
|
||
|
||
pub fn extract_regime_cusum_features(bars: &[Bar]) -> Result<Vec<f64>> {
|
||
let timer = WAVE_D_FEATURE_EXTRACTION_DURATION.start_timer();
|
||
|
||
let features = match compute_features(bars) {
|
||
Ok(f) => {
|
||
// Check for NaN/Inf
|
||
let nan_count = f.iter().filter(|x| x.is_nan()).count();
|
||
let inf_count = f.iter().filter(|x| x.is_infinite()).count();
|
||
|
||
WAVE_D_FEATURES_NAN_COUNT.set(nan_count as f64);
|
||
WAVE_D_FEATURES_INF_COUNT.set(inf_count as f64);
|
||
|
||
f
|
||
}
|
||
Err(e) => return Err(e),
|
||
};
|
||
|
||
drop(timer); // Stop latency measurement
|
||
Ok(features)
|
||
}
|
||
```
|
||
|
||
4. **Expose metrics via service HTTP endpoints**:
|
||
```rust
|
||
// services/ml_training_service/src/main.rs
|
||
use prometheus::TextEncoder;
|
||
|
||
async fn metrics_handler() -> Result<String, StatusCode> {
|
||
let encoder = TextEncoder::new();
|
||
let metric_families = prometheus::gather();
|
||
match encoder.encode_to_string(&metric_families) {
|
||
Ok(s) => Ok(s),
|
||
Err(_) => Err(StatusCode::INTERNAL_SERVER_ERROR),
|
||
}
|
||
}
|
||
|
||
// Mount at /metrics endpoint (already configured in prometheus.yml)
|
||
Router::new().route("/metrics", get(metrics_handler))
|
||
```
|
||
|
||
**Estimated Effort**: 4-6 hours
|
||
- Create `ml/src/regime/metrics.rs` (1 hour)
|
||
- Instrument 8 regime modules (2 hours)
|
||
- Instrument 4 feature modules (1 hour)
|
||
- Verify metrics export via curl (0.5 hours)
|
||
- Test alerts manually (1 hour)
|
||
- Documentation updates (0.5 hours)
|
||
|

|
||
|
||
## 7. Alert Testing Recommendations
|
||
|
||
### 1. Syntax Validation
|
||
|
||
```bash
|
||
# Install promtool
|
||
sudo apt-get install prometheus # or download binary
|
||
|
||
# Validate alert rules
|
||
promtool check rules /home/jgrusewski/Work/foxhunt/config/prometheus/rules/wave_d_alerts.yml
|
||
```
|
||
|
||
**Expected Output**:
|
||
```
|
||
Checking /home/jgrusewski/Work/foxhunt/config/prometheus/rules/wave_d_alerts.yml
|
||
SUCCESS: 9 rules found
|
||
```
|
||
|
||
### 2. Create Alert Unit Tests
|
||
|
||
**File**: `/home/jgrusewski/Work/foxhunt/config/prometheus/rules/wave_d_alerts.test.yml`
|
||
|
||
```yaml
|
||
# Test flip-flopping alert
|
||
rule_files:
|
||
- wave_d_alerts.yml
|
||
|
||
evaluation_interval: 1m
|
||
|
||
tests:
|
||
- interval: 1m
|
||
input_series:
|
||
- series: 'regime_transitions_total'
|
||
values: '0+100x60' # 100 transitions/min for 1 hour = 6000/hour
|
||
|
||
alert_rule_test:
|
||
- eval_time: 5m
|
||
alertname: WaveDFlipFlopping
|
||
exp_alerts:
|
||
- exp_labels:
|
||
severity: critical
|
||
rollback_level: level_1
|
||
component: wave_d_regime_detection
|
||
exp_annotations:
|
||
summary: "Wave D flip-flopping detected (6000 transitions/hour)"
|
||
|
||
- interval: 1m
|
||
input_series:
|
||
- series: 'wave_d_features_nan_count'
|
||
values: '0 0 0 1' # NaN appears at 3m
|
||
|
||
alert_rule_test:
|
||
- eval_time: 4m
|
||
alertname: WaveDDataCorruption
|
||
exp_alerts:
|
||
- exp_labels:
|
||
severity: critical
|
||
rollback_level: level_3
|
||
```
|
||
|
||
**Run Tests**:
|
||
```bash
|
||
promtool test rules wave_d_alerts.test.yml
|
||
```
|
||
|
||
### 3. Manual Alert Triggering (After Metrics Implementation)
|
||
|
||
```bash
|
||
# 1. Start Prometheus and services
|
||
docker-compose up -d
|
||
|
||
# 2. Verify metrics are exported
|
||
curl http://localhost:9091/metrics | grep wave_d
|
||
curl http://localhost:9092/metrics | grep regime
|
||
|
||
# 3. Manually trigger flip-flopping (in test environment)
|
||
# Simulate 100 regime transitions/minute for 10 minutes
|
||
for i in {1..1000}; do
|
||
# Call regime detection API 1000 times rapidly
|
||
curl -X POST http://localhost:50051/api/v1/regime/detect
|
||
sleep 0.06 # 100/min = 1 every 0.6s
|
||
done
|
||
|
||
# 4. Check Prometheus alerts
|
||
curl http://localhost:9090/api/v1/alerts | jq '.data.alerts[] | select(.labels.alertname=="WaveDFlipFlopping")'
|
||
|
||
# 5. Verify Alertmanager receives alert
|
||
curl http://localhost:9093/api/v1/alerts
|
||
```
|
||
|
||
### 4. Integration Test with Alertmanager
|
||
|
||
```bash
|
||
# Send test alert to Alertmanager
|
||
curl -H "Content-Type: application/json" -d '[
|
||
{
|
||
"labels": {
|
||
"alertname": "WaveDFlipFlopping",
|
||
"severity": "critical",
|
||
"rollback_level": "level_1",
|
||
"component": "wave_d_regime_detection"
|
||
},
|
||
"annotations": {
|
||
"summary": "TEST: Wave D flip-flopping detected (100 transitions/hour)",
|
||
"description": "This is a test alert to verify routing and notifications."
|
||
}
|
||
}
|
||
]' http://localhost:9093/api/v1/alerts
|
||
|
||
# Check Slack channel for notification
|
||
# Check webhook endpoint received alert
|
||
curl http://localhost:5001/webhook
|
||
```
|
||
|

|
||
## 8. Recommendations
|
||
|
||
### Priority 1: Implement Missing Metrics (CRITICAL)
|
||
|
||
**Status**: 🔴 **BLOCKING** - Alerts are non-functional without metrics
|
||
|
||
**Action Items**:
|
||
1. Create `ml/src/regime/metrics.rs` with 10 required metrics
|
||
2. Instrument regime detection modules (cusum, bayesian, trending, etc.)
|
||
3. Instrument feature extraction modules (regime_cusum, regime_adx, etc.)
|
||
4. Add NaN/Inf validation to all feature extraction pipelines
|
||
5. Expose metrics via `/metrics` endpoint (already configured in Prometheus)
|
||
6. Test metrics: `curl http://localhost:9094/metrics | grep wave_d`
|
||
|
||
**Estimated Effort**: 4-6 hours
|
||
**Assigned To**: Next agent (suggest Agent WIRE-21: Metrics Implementation)
|
||
|
||
### Priority 2: Validate Alert Syntax (HIGH)
|
||
|
||
**Status**: ⚠️ **UNKNOWN** - Cannot validate without `promtool`
|
||
|
||
**Action Items**:
|
||
1. Install Prometheus tools: `sudo apt-get install prometheus`
|
||
2. Run syntax check: `promtool check rules wave_d_alerts.yml`
|
||
3. Fix any YAML syntax errors
|
||
4. Create unit tests: `wave_d_alerts.test.yml`
|
||
5. Run test suite: `promtool test rules wave_d_alerts.test.yml`
|
||
|
||
**Estimated Effort**: 1 hour
|
||
**Assigned To**: DevOps / Agent WIRE-21
|
||
|
||
### Priority 3: Verify Alertmanager Integration (MEDIUM)
|
||
|
||
**Status**: ⚠️ **INCOMPLETE** - Missing `alerting` section in prometheus.yml
|
||
|
||
**Action Items**:
|
||
1. Add Alertmanager configuration to `prometheus.yml`:
|
||
```yaml
|
||
alerting:
|
||
alertmanagers:
|
||
- static_configs:
|
||
- targets: ['localhost:9093']
|
||
```
|
||
2. Restart Prometheus
|
||
3. Verify integration: `curl http://localhost:9090/api/v1/alertmanagers`
|
||
4. Send test alert (see Section 7.4)
|
||
5. Verify Slack/Email/Webhook notifications
|
||
|
||
**Estimated Effort**: 2 hours
|
||
**Assigned To**: DevOps / Agent WIRE-21
|
||
|
||
### Priority 4: Update Runbook Links (LOW)
|
||
|
||
**Status**: ℹ️ **INFORMATIONAL** - Links reference non-existent GitHub repo
|
||
|
||
**Current Links**:
|
||
```
|
||
runbook: "https://github.com/foxhunt/runbooks/ROLLBACK_PROCEDURES.md#level-1-feature-only-rollback-zero-downtime"
|
||
dashboard: "https://grafana.foxhunt.ai/d/wave-d-monitoring/regime-detection"
|
||
```
|
||
|
||
**Action Items**:
|
||
1. Update GitHub repository URL (if public) OR
|
||
2. Replace with internal wiki/Confluence links OR
|
||
3. Use local file paths: `file:///home/jgrusewski/Work/foxhunt/ROLLBACK_PROCEDURES.md`
|
||
4. Update Grafana dashboard URLs to actual endpoints
|
||
|
||
**Estimated Effort**: 30 minutes
|
||
**Assigned To**: Documentation team
|
||
|
||
### Priority 5: Production Deployment Checklist (MEDIUM)
|
||
|
||
**Before deploying alerts to production**:
|
||
|
||
1. ✅ Metrics implemented and tested
|
||
2. ✅ Alert syntax validated (`promtool check rules`)
|
||
3. ✅ Unit tests passing (`promtool test rules`)
|
||
4. ✅ Alertmanager integration verified
|
||
5. ✅ Slack/Email notifications tested
|
||
6. ✅ Inhibition rules tested (no alert storms)
|
||
7. ✅ Runbook links updated
|
||
8. ✅ Grafana dashboards created
|
||
9. ✅ On-call rotation configured
|
||
10. ✅ Rollback procedures documented and rehearsed
|
||
|
||
**Estimated Effort**: 8 hours (after metrics implementation)
|
||
**Assigned To**: Production deployment team
|
||

||
## 9. Conclusion
|
||
|
||
### Summary of Findings
|
||
|
||
| Component | Status | Impact |
|
||
|---|---|---|
|
||
| Alert Rules File | ✅ EXISTS | Well-structured, 9 rules covering all critical scenarios |
|
||
| Alert Thresholds | ✅ TUNED | Production-ready, appropriate safety margins |
|
||
| Alertmanager Config | ✅ CONFIGURED | Routing, notifications, inhibition rules operational |
|
||
| Prometheus Metrics | ❌ MISSING | **CRITICAL: Zero Wave D metrics exported** |
|
||
| Alerting Integration | ⚠️ INCOMPLETE | Missing `alerting` section in prometheus.yml |
|
||
| Syntax Validation | ⚠️ UNKNOWN | `promtool` not installed |
|
||
| Alert Testing | ❌ MISSING | No unit tests or integration tests |
|
||
|
||
### Overall Assessment
|
||
|
||
🔴 **NOT OPERATIONAL** - Alert rules are well-designed but **cannot function** due to missing metrics exports.
|
||
|
||
**Key Quote from Alert Rules File**:
|
||
```yaml
|
||
# NOTE: If any metrics are missing, alerts will not fire. Ensure all Wave D
|
||
# services expose these metrics via Prometheus endpoints.
|
||
```
|
||
|
||
This warning is **accurate** - all 9 Wave D alerts are currently **non-functional** because the underlying metrics do not exist.
|
||
|
||
### Next Steps
|
||
|
||
**IMMEDIATE** (Priority 1):
|
||
1. Implement Wave D Prometheus metrics (4-6 hours)
|
||
2. Test metrics export via curl
|
||
3. Manually trigger test alerts
|
||
|
||
**SHORT-TERM** (Priority 2-3):
|
||
4. Install `promtool` and validate syntax (1 hour)
|
||
5. Verify Alertmanager integration (2 hours)
|
||
6. Create alert unit tests (2 hours)
|
||
|
||
**BEFORE PRODUCTION**:
|
||
7. Complete Production Deployment Checklist (8 hours)
|
||
8. Rehearse rollback procedures
|
||
9. Configure on-call rotation
|
||
10. Update documentation links
|
||
|
||
### Estimated Total Effort
|
||
|
||
- **Metrics Implementation**: 4-6 hours (CRITICAL PATH)
|
||
- **Alert Validation & Testing**: 5 hours
|
||
- **Production Deployment**: 8 hours
|
||
- **Total**: **17-19 hours** to make alerts fully operational
|
||
|
||
### Recommended Agent Assignment
|
||
|
||
**Agent WIRE-21: Wave D Metrics Implementation**
|
||
- Mission: Implement 10 required Prometheus metrics for Wave D alerts
|
||
- Priority: CRITICAL (blocking production monitoring)
|
||
- Estimated Time: 4-6 hours
|
||
- Deliverable: Functional metrics exported at `/metrics` endpoints
