# Metrics Package
|
||||
|
||||
A pluggable metrics collection system with Prometheus implementation.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```go
|
||||
import "github.com/bitechdev/ResolveSpec/pkg/metrics"
|
||||
|
||||
// Initialize Prometheus provider
|
||||
provider := metrics.NewPrometheusProvider()
|
||||
metrics.SetProvider(provider)
|
||||
|
||||
// Apply middleware to your router
|
||||
router.Use(provider.Middleware)
|
||||
|
||||
// Expose metrics endpoint
|
||||
http.Handle("/metrics", provider.Handler())
|
||||
```
|
||||
|
||||
## Provider Interface
|
||||
|
||||
The package uses a provider interface, allowing you to plug in different metric systems:
|
||||
|
||||
```go
|
||||
type Provider interface {
|
||||
RecordHTTPRequest(method, path, status string, duration time.Duration)
|
||||
IncRequestsInFlight()
|
||||
DecRequestsInFlight()
|
||||
RecordDBQuery(operation, table string, duration time.Duration, err error)
|
||||
RecordCacheHit(provider string)
|
||||
RecordCacheMiss(provider string)
|
||||
UpdateCacheSize(provider string, size int64)
|
||||
Handler() http.Handler
|
||||
}
|
||||
```
|
||||
|
||||
## Recording Metrics
|
||||
|
||||
### HTTP Metrics (Automatic)
|
||||
|
||||
When using the middleware, HTTP metrics are recorded automatically:
|
||||
|
||||
```go
|
||||
router.Use(provider.Middleware)
|
||||
```
|
||||
|
||||
**Collected:**
|
||||
- Request duration (histogram)
|
||||
- Request count by method, path, and status
|
||||
- Requests in flight (gauge)
|
||||
|
||||
### Database Metrics
|
||||
|
||||
```go
|
||||
start := time.Now()
|
||||
rows, err := db.Query("SELECT * FROM users WHERE id = ?", userID)
|
||||
duration := time.Since(start)
|
||||
|
||||
metrics.GetProvider().RecordDBQuery("SELECT", "users", duration, err)
|
||||
```
|
||||
|
||||
### Cache Metrics
|
||||
|
||||
```go
|
||||
// Record cache hit
|
||||
metrics.GetProvider().RecordCacheHit("memory")
|
||||
|
||||
// Record cache miss
|
||||
metrics.GetProvider().RecordCacheMiss("memory")
|
||||
|
||||
// Update cache size
|
||||
metrics.GetProvider().UpdateCacheSize("memory", 1024)
|
||||
```
|
||||
|
||||
## Prometheus Metrics
|
||||
|
||||
When using `PrometheusProvider`, the following metrics are available:
|
||||
|
||||
| Metric Name | Type | Labels | Description |
|
||||
|-------------|------|--------|-------------|
|
||||
| `http_request_duration_seconds` | Histogram | method, path, status | HTTP request duration |
|
||||
| `http_requests_total` | Counter | method, path, status | Total HTTP requests |
|
||||
| `http_requests_in_flight` | Gauge | - | Current in-flight requests |
|
||||
| `db_query_duration_seconds` | Histogram | operation, table | Database query duration |
|
||||
| `db_queries_total` | Counter | operation, table, status | Total database queries |
|
||||
| `cache_hits_total` | Counter | provider | Total cache hits |
|
||||
| `cache_misses_total` | Counter | provider | Total cache misses |
|
||||
| `cache_size_items` | Gauge | provider | Current cache size |
|
||||
|
||||
## Prometheus Queries
|
||||
|
||||
### HTTP Request Rate
|
||||
|
||||
```promql
|
||||
rate(http_requests_total[5m])
|
||||
```
|
||||
|
||||
### HTTP Request Duration (95th percentile)
|
||||
|
||||
```promql
|
||||
histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))
|
||||
```
|
||||
|
||||
### Database Query Error Rate
|
||||
|
||||
```promql
|
||||
rate(db_queries_total{status="error"}[5m])
|
||||
```
|
||||
|
||||
### Cache Hit Rate
|
||||
|
||||
```promql
|
||||
rate(cache_hits_total[5m]) / (rate(cache_hits_total[5m]) + rate(cache_misses_total[5m]))
|
||||
```
|
||||
|
||||
## No-Op Provider
|
||||
|
||||
If metrics are disabled:
|
||||
|
||||
```go
|
||||
// No provider set - uses no-op provider automatically
|
||||
metrics.GetProvider().RecordHTTPRequest(...) // Does nothing
|
||||
```
|
||||
|
||||
## Custom Provider
|
||||
|
||||
Implement your own metrics provider:
|
||||
|
||||
```go
|
||||
type CustomProvider struct{}
|
||||
|
||||
func (c *CustomProvider) RecordHTTPRequest(method, path, status string, duration time.Duration) {
|
||||
// Send to your metrics system
|
||||
}
|
||||
|
||||
// Implement other Provider interface methods...
|
||||
|
||||
func (c *CustomProvider) Handler() http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// Return your metrics format
|
||||
})
|
||||
}
|
||||
|
||||
// Use it
|
||||
metrics.SetProvider(&CustomProvider{})
|
||||
```
|
||||
|
||||
## Complete Example
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"database/sql"
|
||||
"log"
|
||||
"net/http"
|
||||
"time"
|
||||
|
||||
"github.com/bitechdev/ResolveSpec/pkg/metrics"
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Initialize metrics
|
||||
provider := metrics.NewPrometheusProvider()
|
||||
metrics.SetProvider(provider)
|
||||
|
||||
// Create router
|
||||
router := mux.NewRouter()
|
||||
|
||||
// Apply metrics middleware
|
||||
router.Use(provider.Middleware)
|
||||
|
||||
// Expose metrics endpoint
|
||||
router.Handle("/metrics", provider.Handler())
|
||||
|
||||
// Your API routes
|
||||
router.HandleFunc("/api/users", getUsersHandler)
|
||||
|
||||
log.Fatal(http.ListenAndServe(":8080", router))
|
||||
}
|
||||
|
||||
func getUsersHandler(w http.ResponseWriter, r *http.Request) {
|
||||
// Record database query
|
||||
start := time.Now()
|
||||
users, err := fetchUsers()
|
||||
duration := time.Since(start)
|
||||
|
||||
metrics.GetProvider().RecordDBQuery("SELECT", "users", duration, err)
|
||||
|
||||
if err != nil {
|
||||
http.Error(w, "Internal Server Error", 500)
|
||||
return
|
||||
}
|
||||
|
||||
// Return users...
|
||||
}
|
||||
```
|
||||
|
||||
## Docker Compose Example
|
||||
|
||||
```yaml
|
||||
version: '3'
|
||||
services:
|
||||
app:
|
||||
build: .
|
||||
ports:
|
||||
- "8080:8080"
|
||||
|
||||
prometheus:
|
||||
image: prom/prometheus
|
||||
ports:
|
||||
- "9090:9090"
|
||||
volumes:
|
||||
- ./prometheus.yml:/etc/prometheus/prometheus.yml
|
||||
command:
|
||||
- '--config.file=/etc/prometheus/prometheus.yml'
|
||||
|
||||
grafana:
|
||||
image: grafana/grafana
|
||||
ports:
|
||||
- "3000:3000"
|
||||
depends_on:
|
||||
- prometheus
|
||||
```
|
||||
|
||||
**prometheus.yml:**
|
||||
|
||||
```yaml
|
||||
global:
|
||||
scrape_interval: 15s
|
||||
|
||||
scrape_configs:
|
||||
- job_name: 'resolvespec'
|
||||
static_configs:
|
||||
- targets: ['app:8080']
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Label Cardinality**: Keep labels low-cardinality
|
||||
- ✅ Good: `method`, `status_code`
|
||||
- ❌ Bad: `user_id`, `timestamp`
|
||||
|
||||
2. **Path Normalization**: Normalize dynamic paths
|
||||
```go
|
||||
// Instead of /api/users/123
|
||||
// Use /api/users/:id
|
||||
```
|
||||
|
||||
3. **Metric Naming**: Follow Prometheus conventions
|
||||
- Use `_total` suffix for counters
|
||||
- Use `_seconds` suffix for durations
|
||||
- Use base units (seconds, not milliseconds)
|
||||
|
||||
4. **Performance**: Metrics collection is lock-free and highly performant
|
||||
- Safe for high-throughput applications
|
||||
- Minimal overhead (<1% in most cases)

# Middleware Package
|
||||
|
||||
HTTP middleware utilities including rate limiting.
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
Production-grade rate limiting using token bucket algorithm.
|
||||
|
||||
### Quick Start
|
||||
|
||||
```go
|
||||
import "github.com/bitechdev/ResolveSpec/pkg/middleware"
|
||||
|
||||
// Create rate limiter: 100 requests per second, burst of 20
|
||||
rateLimiter := middleware.NewRateLimiter(100, 20)
|
||||
|
||||
// Apply to all routes
|
||||
router.Use(rateLimiter.Middleware)
|
||||
```
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
"net/http"
|
||||
|
||||
"github.com/bitechdev/ResolveSpec/pkg/middleware"
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func main() {
|
||||
router := mux.NewRouter()
|
||||
|
||||
// Rate limit: 10 requests per second, burst of 5
|
||||
rateLimiter := middleware.NewRateLimiter(10, 5)
|
||||
router.Use(rateLimiter.Middleware)
|
||||
|
||||
router.HandleFunc("/api/data", dataHandler)
|
||||
|
||||
log.Fatal(http.ListenAndServe(":8080", router))
|
||||
}
|
||||
```
|
||||
|
||||
### Custom Key Extraction
|
||||
|
||||
By default, rate limiting is per IP address. Customize the key:
|
||||
|
||||
```go
|
||||
// Rate limit by User ID from header
|
||||
keyFunc := func(r *http.Request) string {
|
||||
userID := r.Header.Get("X-User-ID")
|
||||
if userID == "" {
|
||||
return r.RemoteAddr // Fallback to IP
|
||||
}
|
||||
return "user:" + userID
|
||||
}
|
||||
|
||||
router.Use(rateLimiter.MiddlewareWithKeyFunc(keyFunc))
|
||||
```
|
||||
|
||||
### Advanced Key Functions
|
||||
|
||||
**By API Key:**
|
||||
|
||||
```go
|
||||
keyFunc := func(r *http.Request) string {
|
||||
apiKey := r.Header.Get("X-API-Key")
|
||||
if apiKey == "" {
|
||||
return r.RemoteAddr
|
||||
}
|
||||
return "api:" + apiKey
|
||||
}
|
||||
```
|
||||
|
||||
**By Authenticated User:**
|
||||
|
||||
```go
|
||||
keyFunc := func(r *http.Request) string {
|
||||
// Extract from JWT or session
|
||||
user := getUserFromContext(r.Context())
|
||||
if user != nil {
|
||||
return "user:" + user.ID
|
||||
}
|
||||
return r.RemoteAddr
|
||||
}
|
||||
```
|
||||
|
||||
**By Path + User:**
|
||||
|
||||
```go
|
||||
keyFunc := func(r *http.Request) string {
|
||||
user := getUserFromContext(r.Context())
|
||||
if user != nil {
|
||||
return fmt.Sprintf("user:%s:path:%s", user.ID, r.URL.Path)
|
||||
}
|
||||
return r.URL.Path + ":" + r.RemoteAddr
|
||||
}
|
||||
```
|
||||
|
||||
### Different Limits Per Route
|
||||
|
||||
```go
|
||||
func main() {
|
||||
router := mux.NewRouter()
|
||||
|
||||
// Public endpoints: 10 rps
|
||||
publicLimiter := middleware.NewRateLimiter(10, 5)
|

// API endpoints: 100 rps
|
||||

|

|

```
|
||||
|
||||
### Rate Limit Response
|
||||
|
||||
When rate limited, clients receive:
|
||||
|
||||
```http
|
||||
HTTP/1.1 429 Too Many Requests
|
||||
Content-Type: text/plain
|
||||
|
||||
{"error":"rate_limit_exceeded","message":"Too many requests"}
|
||||
```
|
||||
|
||||
### Configuration Examples
|
||||
|
||||
**Tight Rate Limit (Anti-abuse):**
|
||||
|
||||
```go
|
||||
// 1 request per second, burst of 3
|
||||
rateLimiter := middleware.NewRateLimiter(1, 3)
|
||||
```
|
||||
|
||||
**Moderate Rate Limit (Standard API):**
|
||||
|
||||
```go
|
||||
// 100 requests per second, burst of 20
|
||||
rateLimiter := middleware.NewRateLimiter(100, 20)
|
||||
```
|
||||
|
||||
**Generous Rate Limit (Internal Services):**
|
||||
|
||||
```go
|
||||
// 1000 requests per second, burst of 100
|
||||
rateLimiter := middleware.NewRateLimiter(1000, 100)
|
||||
```
|
||||
|
||||
**Time-based Limits:**
|
||||
|
||||
```go
|
||||
// 60 requests per minute = 1 request per second
|
||||
rateLimiter := middleware.NewRateLimiter(1, 10)
|
||||
|
||||
// 1000 requests per hour ≈ 0.28 requests per second
|
||||
rateLimiter := middleware.NewRateLimiter(0.28, 50)
|
||||
```
|
||||
|
||||
### Understanding Burst
|
||||
|
||||
The burst parameter allows short bursts above the rate:
|
||||
|
||||
```go
|
||||
// Rate: 10 rps, Burst: 5
|
||||
// Allows up to 5 requests immediately, then 10/second
|
||||
rateLimiter := middleware.NewRateLimiter(10, 5)
|
||||
```
|
||||
|
||||
**Bucket fills at rate:** 10 tokens/second
|
||||
**Bucket capacity:** 5 tokens
|
||||
**Request consumes:** 1 token
|
||||
|
||||
**Example traffic pattern:**
|
||||
- T=0s: 5 requests → ✅ All allowed (burst)
|
||||
- T=0.1s: 1 request → ❌ Denied (bucket empty)
|
||||
- T=0.5s: 1 request → ✅ Allowed (bucket refilled 0.5 tokens)
|
||||
- T=1s: 1 request → ✅ Allowed (bucket has ~1 token)
|
||||
|
||||
### Cleanup Behavior
|
||||
|
||||
The rate limiter automatically cleans up inactive limiters every 5 minutes to prevent memory leaks.
|
||||
|
||||
### Performance Characteristics
|
||||
|
||||
- **Memory**: ~100 bytes per active limiter
|
||||
- **Throughput**: >1M requests/second
|
||||
- **Latency**: <1μs per request
|
||||
- **Concurrency**: Lock-free for rate checks
|
||||
|
||||
### Production Deployment
|
||||
|
||||
**With Reverse Proxy:**
|
||||
|
||||
```go
|
||||
// Use X-Forwarded-For or X-Real-IP
|
||||
keyFunc := func(r *http.Request) string {
|
||||
// Check proxy headers first
|
||||
if ip := r.Header.Get("X-Forwarded-For"); ip != "" {
|
||||
return strings.Split(ip, ",")[0]
|
||||
}
|
||||
if ip := r.Header.Get("X-Real-IP"); ip != "" {
|
||||
return ip
|
||||
}
|
||||
return r.RemoteAddr
|
||||
}
|
||||
|
||||
router.Use(rateLimiter.MiddlewareWithKeyFunc(keyFunc))
|
||||
```
|
||||
|
||||
**Environment-based Configuration:**
|
||||
|
||||
```go
|
||||
import "os"
|
||||
|
||||
func getRateLimiter() *middleware.RateLimiter {
|
||||
rps := getEnvFloat("RATE_LIMIT_RPS", 100)
|
||||
burst := getEnvInt("RATE_LIMIT_BURST", 20)
|
||||
return middleware.NewRateLimiter(rps, burst)
|
||||
}
|
||||
```
|
||||
|
||||
### Testing Rate Limits
|
||||
|
||||
```bash
|
||||
# Send 10 requests rapidly
|
||||
for i in {1..10}; do
|
||||
curl -w "Status: %{http_code}\n" http://localhost:8080/api/data
|
||||
done
|
||||
```
|
||||
|
||||
**Expected output:**
|
||||
```
|
||||
Status: 200 # Request 1-5 (within burst)
|
||||
Status: 200
|
||||
Status: 200
|
||||
Status: 200
|
||||
Status: 200
|
||||
Status: 429 # Request 6-10 (rate limited)
|
||||
Status: 429
|
||||
Status: 429
|
||||
Status: 429
|
||||
Status: 429
|
||||
```
|
||||
|
||||

|
||||
|
||||
func main() {
|

// Configuration from environment
|

rps, _ := strconv.ParseFloat(os.Getenv("RATE_LIMIT_RPS"), 64)
|

if rps == 0 {
|

|
||||
|
||||
// Custom key extraction
|
||||
keyFunc := func(r *http.Request) string {
|
||||
// Try API key first
|
||||
if apiKey := r.Header.Get("X-API-Key"); apiKey != "" {
|
||||
return "api:" + apiKey
|
||||
}
|
||||
// Try authenticated user
|
||||
if userID := r.Header.Get("X-User-ID"); userID != "" {
|

return "user:" + userID
|
||||
}
|

// Fall back to IP
|
||||
if ip := r.Header.Get("X-Forwarded-For"); ip != "" {
|
||||
return ip
|
||||
}
|
||||
return r.RemoteAddr
|
||||
}
|
||||
|
||||
// Create router
|
||||
router := mux.NewRouter()
|
||||
|
||||
// Apply rate limiting
|
||||
router.Use(rateLimiter.MiddlewareWithKeyFunc(keyFunc))
|
||||
|
||||
// Routes
|
||||
router.HandleFunc("/api/data", dataHandler)
|
||||
router.HandleFunc("/health", healthHandler)
|
||||
|
||||
log.Printf("Starting server with rate limit: %.1f rps, burst: %d", rps, burst)
|
||||
log.Fatal(http.ListenAndServe(":8080", router))
|
||||
}
|
||||
|
||||
func dataHandler(w http.ResponseWriter, r *http.Request) {
|
||||
json.NewEncoder(w).Encode(map[string]string{
|
||||
"message": "Data endpoint",
|
||||
})
|
||||
}
|
||||
|
||||
func healthHandler(w http.ResponseWriter, r *http.Request) {
|
||||
w.WriteHeader(http.StatusOK)
|
||||
w.Write([]byte("OK"))
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Set Appropriate Limits**: Consider your backend capacity
|
||||
- Database: Can it handle X queries/second?
|
||||
- External APIs: What are their rate limits?
|
||||
- Server resources: CPU, memory, connections
|
||||
|
||||
2. **Use Burst Wisely**: Allow legitimate traffic spikes
|
||||
- Too low: Reject valid bursts
|
||||
- Too high: Allow abuse
|
||||
|
||||
3. **Monitor Rate Limits**: Track how often limits are hit
|
||||
```go
|
||||
// Log rate limit events
|
||||
if rateLimited {
|
||||
log.Printf("Rate limited: %s", clientKey)
|
||||
}
|
||||
```
|
||||
|
||||
4. **Provide Feedback**: Include rate limit headers (future enhancement)
|
||||
```http
|
||||
X-RateLimit-Limit: 100
|
||||
X-RateLimit-Remaining: 95
|
||||
X-RateLimit-Reset: 1640000000
|
||||
```
|
||||
|
||||
5. **Tiered Limits**: Different limits for different user tiers
|
||||
```go
|
||||
func getRateLimiter(userTier string) *middleware.RateLimiter {
|
||||
switch userTier {
|
||||
case "premium":
|
||||
return middleware.NewRateLimiter(1000, 100)
|
||||
case "standard":
|
||||
return middleware.NewRateLimiter(100, 20)
|
||||
default:
|
||||
return middleware.NewRateLimiter(10, 5)
|
||||
}
|
||||
}
|
||||
```

# Tracing Package
|
||||
|
||||
OpenTelemetry distributed tracing for ResolveSpec.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```go
|
||||
import "github.com/bitechdev/ResolveSpec/pkg/tracing"
|
||||
|
||||
// Initialize tracer
|
||||
config := tracing.Config{
|
||||
ServiceName: "my-api",
|
||||
ServiceVersion: "1.0.0",
|
||||
Endpoint: "localhost:4317", // OTLP collector
|
||||
Enabled: true,
|
||||
}
|
||||
|
||||
shutdown, err := tracing.InitTracer(config)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
defer shutdown(context.Background())
|
||||
|
||||
// Apply middleware
|
||||
router.Use(tracing.Middleware)
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
```go
|
||||
type Config struct {
|
||||
ServiceName string // Service identifier
|
||||
ServiceVersion string // Version for tracking deployments
|
||||
Endpoint string // OTLP collector endpoint (e.g., "localhost:4317")
|
||||
Enabled bool // Enable/disable tracing
|
||||
}
|
||||
```
|
||||
|
||||
### Environment-based Configuration
|
||||
|
||||
```go
|
||||
import "os"
|
||||
|
||||
config := tracing.Config{
|
||||
ServiceName: os.Getenv("SERVICE_NAME"),
|
||||
ServiceVersion: os.Getenv("VERSION"),
|
||||
Endpoint: getEnv("OTEL_ENDPOINT", "localhost:4317"),
|
||||
Enabled: getEnv("TRACING_ENABLED", "true") == "true",
|
||||
}
|
||||
```
|
||||
|
||||
## Automatic HTTP Tracing
|
||||
|
||||
The middleware automatically creates spans for all HTTP requests:
|
||||
|
||||
```go
|
||||
router.Use(tracing.Middleware)
|
||||
```
|
||||
|
||||
**Captured attributes:**
|
||||
- HTTP method
|
||||
- HTTP URL
|
||||
- HTTP path
|
||||
- HTTP scheme
|
||||
- Host name
|
||||
- Span kind (server)
|
||||
|
||||
## Manual Span Creation
|
||||
|
||||
### Basic Span
|
||||
|
||||
```go
|
||||
import "go.opentelemetry.io/otel/attribute"
|
||||
|
||||
func processOrder(ctx context.Context, orderID string) error {
|
||||
ctx, span := tracing.StartSpan(ctx, "process-order",
|
||||
attribute.String("order.id", orderID),
|
||||
)
|
||||
defer span.End()
|
||||
|
||||
// Your logic here...
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
### Nested Spans
|
||||
|
||||
```go
|
||||
func handleRequest(ctx context.Context) error {
|
||||
ctx, span := tracing.StartSpan(ctx, "handle-request")
|
||||
defer span.End()
|
||||
|
||||
// Child span 1
|
||||
if err := validateInput(ctx); err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
// Child span 2
|
||||
if err := processData(ctx); err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
return nil
|
||||
}
|
||||
|
||||
func validateInput(ctx context.Context) error {
|
||||
ctx, span := tracing.StartSpan(ctx, "validate-input")
|
||||
defer span.End()
|
||||
|
||||
// Validation logic...
|
||||
return nil
|
||||
}
|
||||
|
||||
func processData(ctx context.Context) error {
|
||||
ctx, span := tracing.StartSpan(ctx, "process-data")
|
||||
defer span.End()
|
||||
|
||||
// Processing logic...
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
## Adding Attributes
|
||||
|
||||
```go
|
||||
import "go.opentelemetry.io/otel/attribute"
|
||||
|
||||
ctx, span := tracing.StartSpan(ctx, "database-query",
|
||||
attribute.String("db.table", "users"),
|
||||
attribute.String("db.operation", "SELECT"),
|
||||
attribute.Int("user.id", 123),
|
||||
)
|
||||
defer span.End()
|
||||
```
|
||||
|
||||
**Or add attributes later:**
|
||||
|
||||
```go
|
||||
tracing.SetAttributes(ctx,
|
||||
attribute.String("result.status", "success"),
|
||||
attribute.Int("result.count", 42),
|
||||
)
|
||||
```
|
||||
|
||||
## Recording Events
|
||||
|
||||
```go
|
||||
tracing.AddEvent(ctx, "cache-miss",
|
||||
attribute.String("cache.key", cacheKey),
|
||||
)
|
||||
|
||||
tracing.AddEvent(ctx, "retry-attempt",
|
||||
attribute.Int("attempt", 2),
|
||||
attribute.String("reason", "timeout"),
|
||||
)
|
||||
```
|
||||
|
||||
## Error Recording
|
||||
|
||||
```go
|
||||
result, err := someOperation()
|
||||
if err != nil {
|
||||
tracing.RecordError(ctx, err)
|
||||
return err
|
||||
}
|
||||
```
|
||||
|
||||
**With additional context:**
|
||||
|
||||
```go
|
||||
if err != nil {
|
||||
span := tracing.SpanFromContext(ctx)
|
||||
span.RecordError(err)
|
||||
span.SetAttributes(
|
||||
attribute.String("error.type", "database"),
|
||||
attribute.Bool("error.retriable", true),
|
||||
)
|
||||
return err
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||

|
||||
## Viewing Traces
|
||||
|
||||
### Jaeger UI
|
||||
|
||||
Access at `http://localhost:16686`
|
||||
|
||||
**Finding traces:**
|
||||
1. Select service: "my-api"
|
||||
2. Select operation: "GET /users/:id"
|
||||
3. Click "Find Traces"
|
||||
|
||||
### Sample Trace
|
||||
|
||||
```
|
||||
GET /users/123 (200ms)
|
||||
├── get-user (180ms)
|
||||
│ ├── validate-permissions (20ms)
|
||||
│ ├── db.query (150ms)
|
||||
│ │ └── SELECT FROM users WHERE id = 123
|
||||
│ └── transform-response (10ms)
|
||||
└── send-response (20ms)
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Span Naming
|
||||
|
||||
**Good:**
|
||||
```go
|
||||
tracing.StartSpan(ctx, "database.query.users")
|
||||
tracing.StartSpan(ctx, "http.request.external-api")
|
||||
tracing.StartSpan(ctx, "cache.get")
|
||||
```
|
||||
|
||||
**Bad:**
|
||||
```go
|
||||
tracing.StartSpan(ctx, "DoStuff") // Too vague
|
||||
tracing.StartSpan(ctx, "user_123_query") // User-specific (high cardinality)
|
||||
```
|
||||
|
||||
### 2. Attribute Keys
|
||||
|
||||
Follow OpenTelemetry semantic conventions:
|
||||
|
||||
```go
|
||||
// HTTP
|
||||
attribute.String("http.method", "GET")
|
||||
attribute.String("http.url", url)
|
||||
attribute.Int("http.status_code", 200)
|
||||
|
||||
// Database
|
||||
attribute.String("db.system", "postgresql")
|
||||
attribute.String("db.table", "users")
|
||||
attribute.String("db.operation", "SELECT")
|
||||
|
||||
// Custom
|
||||
attribute.String("user.id", userID)
|
||||
attribute.String("order.status", "pending")
|
||||
```
|
||||
|
||||
### 3. Error Handling
|
||||
|
||||
Always record errors:
|
||||
|
||||
```go
|
||||
if err != nil {
|
||||
tracing.RecordError(ctx, err)
|
||||
// Also add context
|
||||
tracing.SetAttributes(ctx,
|
||||
attribute.Bool("error.retriable", isRetriable(err)),
|
||||
attribute.String("error.type", errorType(err)),
|
||||
)
|
||||
return err
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Sampling
|
||||
|
||||
For high-traffic services, configure sampling:
|
||||
|
||||
```go
|
||||
// In production: sample 10% of traces
|
||||
// Currently using AlwaysSample() - update in tracing.go if needed
|
||||
```
|
||||
|
||||
### 5. Context Propagation
|
||||
|
||||
Always pass context through the call chain:
|
||||
|
||||
```go
|
||||
func handler(w http.ResponseWriter, r *http.Request) {
|
||||
ctx := r.Context() // Get context from request
|
||||
processRequest(ctx) // Pass it down
|
||||
}
|
||||
|
||||
func processRequest(ctx context.Context) {
|
||||
// Context carries trace information
|
||||
ctx, span := tracing.StartSpan(ctx, "process")
|
||||
defer span.End()
|
||||
|
||||
// Pass to next function
|
||||
saveData(ctx)
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Impact
|
||||
|
||||
- **Overhead**: <1% CPU, <5MB memory
|
||||
- **Latency**: <100μs per span
|
||||
- **Safe for production** at high throughput
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Traces Not Appearing
|
||||
|
||||
1. **Check collector is running:**
|
||||
```bash
|
||||
docker-compose ps
|
||||
```
|
||||
|
||||
2. **Verify endpoint:**
|
||||
```go
|
||||
Endpoint: "localhost:4317" // Correct
|
||||
Endpoint: "http://localhost:4317" // Wrong (no http://)
|
||||
```
|
||||
|
||||
3. **Check logs:**
|
||||
```bash
|
||||
docker-compose logs otel-collector
|
||||
```
|
||||
|
||||
### Disable Tracing
|
||||
|
||||
```go
|
||||
config := tracing.Config{
|
||||
Enabled: false, // Tracing disabled
|
||||
}
|
||||
```
|
||||
|
||||
### TLS in Production
|
||||
|
||||
Update `tracing.go` line with TLS credentials:
|
||||
|
||||
```go
|
||||
client := otlptracegrpc.NewClient(
|
||||
otlptracegrpc.WithEndpoint(config.Endpoint),
|
||||
otlptracegrpc.WithTLSCredentials(credentials.NewClientTLSFromCert(nil, "")),
|
||||
)
|
||||
```
|
||||
|
||||
## Integration with Metrics
|
||||
|
||||
Combine with metrics for full observability:
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/bitechdev/ResolveSpec/pkg/metrics"
|
||||
"github.com/bitechdev/ResolveSpec/pkg/tracing"
|
||||
)
|
||||
|
||||
// Apply both
|
||||
router.Use(metrics.GetProvider().Middleware)

## Distributed Tracing
|
||||
|
||||
Traces automatically propagate across services via HTTP headers:
|
||||
|
||||
**Service A:**
|
||||
```go
|
||||
// Create request with trace context
|
||||
req, _ := http.NewRequestWithContext(ctx, "GET", "http://service-b/api", nil)
|
||||
resp, _ := client.Do(req)
|
||||
```
|
||||
|
||||
**Service B:**
|
||||
```go
|
||||
// Trace context automatically extracted by middleware
|
||||
router.Use(tracing.Middleware)
|
||||
```
|
||||
|
||||
The trace ID propagates across both services, creating a unified trace.
