# MEV Bot Monitoring & Metrics Infrastructure Survey
|
||||
## Production Deployment Gap Analysis
|
||||
|
||||
**Date:** October 23, 2025
|
||||
**Status:** Medium Thoroughness Assessment
|
||||
**Overall Readiness:** 65% (Moderate Gaps Identified)
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The MEV bot has **substantial monitoring infrastructure** with custom health checking, data integrity monitoring, and basic metrics exposure. However, **critical production gaps exist** in:
|
||||
- Prometheus-standard metrics export
|
||||
- Distributed tracing/observability
|
||||
- Kubernetes-native probes (readiness/liveness/startup)
|
||||
- SLO/SLA frameworks
|
||||
- Production-grade performance profiling
|
||||
|
||||
---
|
||||
|
||||
## 1. Metrics Collection & Export
|
||||
|
||||
### CURRENT IMPLEMENTATION: 65% Complete
|
||||
|
||||
#### What's Working:
|
||||
- **Custom Metrics Server** (`pkg/metrics/metrics.go`)
|
||||
- JSON metrics endpoint at `/metrics`
|
||||
- Manual Prometheus format at `/metrics/prometheus`
|
||||
- Business metrics: L2 messages, arbitrage opportunities, trades, profits
|
||||
- Auth-protected endpoints (127.0.0.1 only)
|
||||
- Port configurable via `METRICS_PORT` env var (default: 9090)
|
||||
|
||||
- **Metrics Collected:**
|
||||
- L2 message processing (rate, lag)
|
||||
- DEX interactions & swap opportunities
|
||||
- Trade success/failure rates & profits
|
||||
- Gas costs and profit factors
|
||||
- System uptime in seconds
|
||||
|
||||
#### Critical GAPS:
|
||||
- **NO Prometheus client library integration** - Manual text formatting instead of `prometheus/client_golang`
|
||||
- **NO histogram/distribution metrics** - Only point-in-time values
|
||||
- **NO custom metric registration** - Cannot add new metrics without modifying core code
|
||||
- **NO metric cardinality control** - Risk of metric explosion
|
||||
- **NO scrape-friendly format validation** - Manual string concatenation prone to syntax errors
|
||||
- **NO metrics retention** - Snapshots lost on restart
|
||||
- **NO dimensional/labeled metrics** - Cannot slice data by operation, module, or error type
|
||||
|
||||
#### Recommendation:
|
||||
```go
|
||||
import "github.com/prometheus/client_golang/prometheus"
|
||||
import "github.com/prometheus/client_golang/prometheus/promhttp"
|
||||
|
||||
// Replace manual metrics with Prometheus client
|
||||
var (
|
||||
l2MessagesTotal = prometheus.NewCounterVec(
|
||||
prometheus.CounterOpts{Name: "mev_bot_l2_messages_total"},
|
||||
[]string{"status"},
|
||||
)
|
||||
processingLatency = prometheus.NewHistogramVec(
|
||||
prometheus.HistogramOpts{
|
||||
Name: "mev_bot_processing_latency_seconds",
|
||||
Buckets: prometheus.DefBuckets,
|
||||
},
|
||||
[]string{"stage"},
|
||||
)
|
||||
)
|
||||
|
||||
// Serve at /metrics using promhttp.Handler()
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 2. Performance Monitoring & Profiling Hooks
|
||||
|
||||
### CURRENT IMPLEMENTATION: 50% Complete
|
||||
|
||||
#### What's Working:
|
||||
- **Performance Profiler** (`pkg/security/performance_profiler.go`)
|
||||
- Operation-level performance tracking
|
||||
- Resource usage monitoring (heap, goroutines, GC)
|
||||
- Performance classification (excellent/good/average/poor/critical)
|
||||
- Alert generation for threshold violations
|
||||
- Comprehensive report generation with bottleneck analysis
|
||||
- **2,000+ lines of detailed profiling infrastructure**
|
||||
|
||||
- **Profiling Features:**
|
||||
- Min/max/avg response times per operation
|
||||
- Error rate tracking and trend analysis
|
||||
- Memory efficiency scoring
|
||||
- CPU efficiency calculation
|
||||
- GC efficiency metrics
|
||||
- Recommendations for optimization
|
||||
|
||||
#### Critical GAPS:
|
||||
- **NO pprof integration** - Cannot attach to `net/http/pprof` for live profiling
|
||||
- **NO CPU profiling endpoint** - No `/debug/pprof/profile` available
|
||||
- **NO memory profiling endpoint** - No heap dump capability
|
||||
- **NO goroutine profiling** - Cannot inspect goroutine stacks
|
||||
- **NO flamegraph support** - No integration with go-torch or pprof web UI
|
||||
- **NO continuous profiling** - Manual operation tracking only
|
||||
- **NO profile persistence** - Reports generated in-memory, not saved
|
||||
|
||||
#### Implementation Status:
|
||||
```go
|
||||
// Currently exists:
|
||||
pp := NewPerformanceProfiler(logger, config)
|
||||
tracker := pp.StartOperation("my_operation")
|
||||
// ... do work ...
|
||||
tracker.End()
|
||||
report, _ := pp.GenerateReport() // Custom report
|
||||
|
||||
// MISSING:
|
||||
import _ "net/http/pprof"
|
||||
// http://localhost:6060/debug/pprof/profile?seconds=30
|
||||
// http://localhost:6060/debug/pprof/heap
|
||||
// http://localhost:6060/debug/pprof/goroutine
|
||||
```
|
||||
|
||||
#### Recommendation:
|
||||
```go
|
||||
import _ "net/http/pprof"
|
||||
|
||||
// In main startup
|
||||
go func() {
|
||||
log.Info("pprof server starting", "addr", ":6060")
|
||||
log.Error("pprof error", "err", http.ListenAndServe(":6060", nil))
|
||||
}()
|
||||
|
||||
// Now supports:
|
||||
// curl http://localhost:6060/debug/pprof/ - profile index
|
||||
// go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30 - CPU
|
||||
// go tool pprof http://localhost:6060/debug/pprof/heap - Memory
|
||||
// go tool pprof http://localhost:6060/debug/pprof/goroutine - Goroutines
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 3. Real-Time Alerting & Dashboard Systems
|
||||
|
||||
### CURRENT IMPLEMENTATION: 75% Complete
|
||||
|
||||
#### What's Working:
|
||||
- **Alert Handlers** (`internal/monitoring/alert_handlers.go`)
|
||||
- Log-based alerts (structured logging)
|
||||
- File-based alerts (JSON JSONL format)
|
||||
- HTTP webhook support (Slack, Discord, generic)
|
||||
- Metrics-based counters
|
||||
- Composite handler pattern (multiple handlers)
|
||||
- Automatic webhook type detection (Slack vs Discord)
|
||||
- Retry logic with exponential backoff (3 retries)
|
||||
|
||||
- **Monitoring Dashboard** (`internal/monitoring/dashboard.go`)
|
||||
- HTML5 responsive dashboard at port 8080 (configurable)
|
||||
- Real-time health metrics display
|
||||
- Auto-refresh every 30 seconds
|
||||
- JSON API endpoints:
|
||||
- `/api/health` - current health status
|
||||
- `/api/metrics` - system metrics
|
||||
- `/api/history?count=N` - historical snapshots
|
||||
- `/api/alerts?limit=N` - alert records
|
||||
- Integrity monitoring metrics display
|
||||
- Performance classification cards
|
||||
- Recovery action tracking
|
||||
|
||||
#### Critical GAPS:
|
||||
- **NO email alerts** - Only webhooks/logging
|
||||
- **NO SMS/Slack bot integration** - Only generic webhooks
|
||||
- **NO alert aggregation/deduplication** - Every alert fires independently
|
||||
- **NO alert silencing/suppression** - Cannot silence known issues
|
||||
- **NO correlation/grouping** - Similar alerts not grouped
|
||||
- **NO escalation policies** - No severity-based notification routing
|
||||
- **NO PagerDuty integration** - Cannot create incidents
|
||||
- **NO dashboard persistence** - Metrics reset on restart
|
||||
- **NO multi-user access control** - No RBAC for dashboard
|
||||
- **NO alert acknowledgment/tracking** - No alert lifecycle management
|
||||
- **NO custom dashboard widgets** - Fixed layout
|
||||
|
||||
#### Recommendation (Priority: HIGH):
|
||||
```go
|
||||
// Add alert correlation and deduplication
|
||||
type AlertManager struct {
|
||||
alerts map[string]*Alert // deduplicated by fingerprint
|
||||
suppressions map[string]time.Time
|
||||
escalations map[AlertSeverity][]Handler
|
||||
}
|
||||
|
||||
// Add PagerDuty integration
|
||||
import "github.com/PagerDuty/go-pagerduty"
|
||||
|
||||
// Add email support
|
||||
import "net/smtp"
|
||||
|
||||
// Implement alert lifecycle
|
||||
type Alert struct {
|
||||
ID string
|
||||
Status AlertStatus // TRIGGERED, ACKNOWLEDGED, RESOLVED
|
||||
AckTime time.Time
|
||||
Resolution string
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 4. Health Check & Readiness Probe Implementations
|
||||
|
||||
### CURRENT IMPLEMENTATION: 55% Complete
|
||||
|
||||
#### What's Working:
|
||||
- **Metrics Health Endpoint** (`pkg/metrics/metrics.go`)
|
||||
- `/health` endpoint returns JSON status
|
||||
- Updates last_health_check timestamp
|
||||
- Returns HTTP 200 when healthy
|
||||
- Simple liveness indicator
|
||||
|
||||
- **Lifecycle Health Monitor** (`pkg/lifecycle/health_monitor.go`)
|
||||
- Comprehensive module health tracking
|
||||
- Parallel/sequential health checks
|
||||
- Check timeout enforcement
|
||||
- Health status aggregation
|
||||
- Health trends (improving/stable/degrading/critical)
|
||||
- Notification on status changes
|
||||
- Configurable failure/recovery thresholds
|
||||
- 1,000+ lines of health management
|
||||
|
||||
- **Integrity Health Runner** (`internal/monitoring/health_checker.go`)
|
||||
- Periodic health checks (30s default)
|
||||
- Health history tracking (last 100 snapshots)
|
||||
- Corruption rate monitoring
|
||||
- Validation success tracking
|
||||
- Contract call success rate
|
||||
- Health trend calculation
|
||||
- Warm-up suppression (prevents early false alerts)
|
||||
|
||||
#### Critical GAPS:
|
||||
- **NO Kubernetes liveness probe format** - Only JSON, not Kubernetes-compatible
|
||||
- **NO startup probe** - Cannot detect initialization delays
|
||||
- **NO readiness probe** - Cannot detect degraded-but-running state
|
||||
- **NO individual service probes** - Cannot probe individual modules
|
||||
- **NO external health check integration** - Only self-checks
|
||||
- **NO health check history export** - Cannot retrieve past health data
|
||||
- **NO SLO-based health thresholds** - Thresholds hardcoded
|
||||
- **NO health events/timestamps** - Only current status
|
||||
- **NO health check dependencies** - Cannot define "Module A healthy only if Module B healthy"
|
||||
|
||||
#### Kubernetes Probes Implementation (CRITICAL MISSING):
|
||||
|
||||
The application is **NOT Kubernetes-ready** without these probes:
|
||||
|
||||
```yaml
|
||||
# MISSING CONFIG - Must be added to deployment
|
||||
livenessProbe:
|
||||
httpGet:
|
||||
path: /health/live # NOT IMPLEMENTED
|
||||
port: 9090
|
||||
initialDelaySeconds: 30
|
||||
periodSeconds: 10
|
||||
|
||||
readinessProbe:
|
||||
httpGet:
|
||||
path: /health/ready # NOT IMPLEMENTED
|
||||
port: 9090
|
||||
initialDelaySeconds: 5
|
||||
periodSeconds: 5
|
||||
|
||||
startupProbe:
|
||||
httpGet:
|
||||
path: /health/startup # NOT IMPLEMENTED
|
||||
port: 9090
|
||||
failureThreshold: 30
|
||||
periodSeconds: 10
|
||||
```
|
||||
|
||||
#### Recommendation (Priority: CRITICAL):
|
||||
```go
|
||||
// Add Kubernetes-compatible probes
|
||||
func handleLivenessProbe(w http.ResponseWriter, r *http.Request) {
|
||||
// Return 200 if process is still running
|
||||
// Return 500 if deadlock detected (watchdog timeout)
|
||||
status := "ok"
|
||||
if time.Since(lastHeartbeat) > 2*time.Minute {
|
||||
w.WriteHeader(http.StatusInternalServerError)
|
||||
w.Write([]byte(`{"status": "deadlock_detected"}`))
|
||||
return
|
||||
}
|
||||
w.WriteHeader(http.StatusOK)
|
||||
w.Write([]byte(`{"status": "` + status + `"}`))
|
||||
}
|
||||
|
||||
func handleReadinessProbe(w http.ResponseWriter, r *http.Request) {
|
||||
// Return 200 only if:
|
||||
// 1. RPC connection healthy
|
||||
// 2. Database healthy
|
||||
// 3. All critical services initialized
|
||||
// 4. No degraded conditions
|
||||
if !isReady() {
|
||||
w.WriteHeader(http.StatusServiceUnavailable)
|
||||
w.Write([]byte(`{"status": "not_ready", "reason": "..."`))
|
||||
return
|
||||
}
|
||||
w.WriteHeader(http.StatusOK)
|
||||
w.Write([]byte(`{"status": "ready"}`))
|
||||
}
|
||||
|
||||
func handleStartupProbe(w http.ResponseWriter, r *http.Request) {
|
||||
// Return 200 only after initialization complete
|
||||
// Can take up to 5 minutes for complex startup
|
||||
if !isInitialized {
|
||||
w.WriteHeader(http.StatusServiceUnavailable)
|
||||
return
|
||||
}
|
||||
w.WriteHeader(http.StatusOK)
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 5. Production Logging & Audit Trail Systems
|
||||
|
||||
### CURRENT IMPLEMENTATION: 80% Complete
|
||||
|
||||
#### What's Working:
|
||||
- **Structured Logging** (`internal/logger/logger.go`)
|
||||
- Slog integration with JSON/text formats
|
||||
- Multiple log levels (debug, info, warn, error)
|
||||
- File output with configurable paths
|
||||
- Configurable via environment
|
||||
- Key-value pair support
|
||||
|
||||
- **Secure Filter** (`internal/logger/secure_filter.go`)
|
||||
- Filters sensitive data (keys, passwords, secrets)
|
||||
- Prevents credential leaks in logs
|
||||
- Pattern-based filtering
|
||||
- Audit-safe output
|
||||
|
||||
- **Audit Logging** (`internal/logger/secure_audit.go`)
|
||||
- Security event logging
|
||||
- Transaction tracking
|
||||
- Key operation audit trail
|
||||
- Configurable audit log file
|
||||
|
||||
- **Log Rotation (External)**
|
||||
- `scripts/log-manager.sh` - comprehensive log management
|
||||
- Archiving with compression
|
||||
- Health monitoring
|
||||
- Real-time analysis
|
||||
- Performance tracking
|
||||
- Daemon monitoring
|
||||
|
||||
#### Critical GAPS:
|
||||
- **NO audit log integrity verification** - Cannot verify logs haven't been tampered
|
||||
- **NO log aggregation client** - No ELK/Splunk/Datadog shipping
|
||||
- **NO log correlation IDs** - Cannot trace requests across services
|
||||
- **NO log rate limiting** - Could be DoS'd with logs
|
||||
- **NO structured event schema validation** - Logs could have inconsistent structure
|
||||
- **NO log retention policies** - Manual cleanup only
|
||||
- **NO encrypted log storage** - Audit logs unencrypted at rest
|
||||
- **NO log signing/verification** - No cryptographic integrity proof
|
||||
- **NO compliance logging** (GDPR/SOC2)** - No data residency controls
|
||||
|
||||
#### Recommendation (Priority: MEDIUM):
|
||||
```go
|
||||
// Add correlation IDs
|
||||
type RequestContext struct {
|
||||
CorrelationID string // Unique per request
|
||||
UserID string
|
||||
Timestamp time.Time
|
||||
}
|
||||
|
||||
// Add structured audit events
|
||||
type AuditEvent struct {
|
||||
EventType string `json:"event_type"`
|
||||
Timestamp time.Time `json:"timestamp"`
|
||||
Actor string `json:"actor"`
|
||||
Resource string `json:"resource"`
|
||||
Action string `json:"action"`
|
||||
Result string `json:"result"` // success/failure
|
||||
Reason string `json:"reason"` // if failure
|
||||
CorrelationID string `json:"correlation_id"`
|
||||
}
|
||||
|
||||
// Add log forwarding
|
||||
import "github.com/fluent/fluent-logger-golang/fluent"
|
||||
```
