Monitor Setup

# === BetterUptime Configuration ===



# Monitor Types:

# 1. HTTP Monitor — ตรวจ Status Code + Response Time

# 2. TCP Monitor — ตรวจ Port เปิด

# 3. DNS Monitor — ตรวจ DNS Resolution

# 4. Heartbeat — ตรวจ Cron Job ทำงาน

# 5. Keyword — ตรวจ Keyword ใน Page



# API — Create Monitor

# curl -X POST https://betteruptime.com/api/v2/monitors \

#   -H "Authorization: Bearer TOKEN" \

#   -H "Content-Type: application/json" \

#   -d '{

#     "monitor_type": "status",

#     "url": "https://api.example.com/health",

#     "pronounceable_name": "API Health Check",

#     "check_frequency": 30,

#     "request_timeout": 15,

#     "confirmation_period": 3,

#     "regions": ["us", "eu", "ap"],

#     "expected_status_codes": [200],

#     "domain_expiration": 30,

#     "ssl_expiration": 14,

#     "follow_redirects": true,

#     "policy_id": "escalation-policy-id"

#   }'



# Terraform — Infrastructure as Code

#   monitor_type     = "status"

#   url              = "https://api.example.com/health"

SLA Management

# === SLA/SLO/SLI ===



# SLI (Service Level Indicator) — ตัววัด

# - Availability: % time service is up

# - Latency: p50, p95, p99 response time

# - Error Rate: % of 5xx responses

# - Throughput: requests per second



# SLO (Service Level Objective) — เป้าหมาย

# - Availability: 99.9%

# - Latency p99: < 500ms

# - Error Rate: < 0.1%



# SLA (Service Level Agreement) — สัญญา

# - 99.9% uptime = max 8h 45m downtime/year

# - Credit if SLA breached



@dataclass

class SLATarget:

    service: str

    sla_pct: float

    max_downtime_month: str

    current_uptime: float

    error_budget_remaining: str

    status: str



sla_targets = [

    SLATarget("API Gateway", 99.95, "21 min", 99.97, "65%", "Healthy"),

    SLATarget("Web App", 99.9, "43 min", 99.95, "80%", "Healthy"),

    SLATarget("Database", 99.99, "4 min", 99.995, "90%", "Healthy"),

    SLATarget("CDN", 99.9, "43 min", 99.85, "15%", "At Risk"),

    SLATarget("Auth Service", 99.95, "21 min", 99.93, "35%", "Warning"),

]



print("SLA Dashboard:")

for s in sla_targets:

    emoji = "OK" if s.status == "Healthy" else s.status.upper()

    print(f"  [{emoji}] {s.service}")

    print(f"    SLA: {s.sla_pct}% | Current: {s.current_uptime}%")

    print(f"    Max Down: {s.max_downtime_month}/mo | Budget: {s.error_budget_remaining}")



# Uptime Calculation

print(f"\n\nUptime Reference:")

uptimes = {

    "99%": "7h 18m/month, 3.65 days/year",

    "99.9%": "43m 50s/month, 8h 46m/year",

    "99.95%": "21m 55s/month, 4h 23m/year",

    "99.99%": "4m 23s/month, 52m 36s/year",

เคล็ดลับ

• Multi-region: Monitor จากหลาย Region ป้องกัน False Positive
• Confirmation: ตั้ง Confirmation Period ก่อน Alert
• Game Day: ซ้อม Incident Response ทุกเดือน
• Error Budget: ติดตาม Error Budget ไม่ให้หมด
• Status Page: สร้าง Status Page สำหรับลูกค้า
