How do I configure certificate expiration monitoring?

How do I configure certificate expiration monitoring?

Certificate expiration monitoring prevents service outages caused by expired TLS/SSL certificates. DataPower Gateway sends SNMP traps when certificates approach expiration, enabling proactive renewal.

DataPower Appliance Configuration

Step 1: Configure SNMP Settings

  1. Login to DataPower WebGUI (HTTPS://appliance-ip:9090)
  2. Navigate: Objects → SNMP Settings
  3. Create SNMP Trap Destination:
    • Name: Nodinite-Agent-Prod
    • Target IP address: Nodinite Agent IP (e.g., 10.20.1.15)
    • Port: 162 (standard SNMP trap port)
    • SNMP version: v2c or v3 (v3 recommended for encrypted traps)
    • Community string (v2c): nodinite-datapower (shared secret)
    • Security credentials (v3): Configure SNMPv3 user with authPriv protocol

Step 2: Create Notification Rule for Certificate Expiration

  1. Navigate: Objects → Logging Configuration → Notification

  2. Create Notification Rule:

    • Name: Certificate-Expiring-90days
    • Event type: "Certificate Expiring" (OID: oidCertificateExpiring)
    • Severity: Warning (not yet critical, proactive notification)
    • Days before expiration: 90 (configurable: 30, 60, 90, or 120 days)
    • Trap destination: Nodinite-Agent-Prod (created in Step 1)

  3. Associate notification rule with trap destination:

    • Edit SNMP Trap Destination → Add Notification Rule → Select "Certificate-Expiring-90days"

Step 3: Test SNMP Trap

  1. Navigate: Objects → Crypto Certificate
  2. Identify certificate expiring soon (certificate with expiration date <90 days from today)
  3. Trigger manual test: Some DataPower firmware versions support "Send Test Notification" button in Notification Rule configuration
  4. Verify: Check Nodinite Agent logs for received SNMP trap with OID oidCertificateExpiring

Note: If no certificates expire within 90 days, DataPower won't send traps immediately. Trap fires automatically when certificate crosses 90-day threshold.

Nodinite Configuration

Step 1: Create SNMP Notification Rule Resource

  1. Navigate: Nodinite Web Client → Repository → Monitoring Resources
  2. Create New Resource:
    • Resource type: SNMP Notification Rule
    • Name: DataPower Certificate Expiration Alerts
    • DataPower appliance: Prod-Primary (or appliance name)
    • OID filter: oidCertificateExpiring (filters only certificate expiration traps)

Step 2: Configure Threshold Alerts

  1. Set thresholds based on days remaining:

    • Warning (<90 days): Email operations team for planning (Subject: "DataPower Certificate Renewal Required - 90 days remaining")
    • Error (<30 days): Slack alert #datapower-alerts + email IT manager (urgency increasing)
    • Critical (<7 days): PagerDuty page on-call engineer (immediate action required, service outage risk)

  2. Threshold configuration example:

Warning:  DaysRemaining <90 AND >=30 → Email operations@company.com
Error:    DaysRemaining <30 AND >=7  → Slack #datapower-alerts + Email it-manager@company.com
Critical: DaysRemaining <7            → PagerDuty incident (severity: high, auto-escalate after 15 minutes)

Step 3: Create Monitor View for Certificate Dashboard

  1. Navigate: Nodinite Web Client → Monitor → Create Monitor View

  2. Monitor View configuration:

    • Name: DataPower Certificate Dashboard
    • Resource type filter: SNMP Notification Rule (certificate expiration only)
    • Group by: DataPower appliance name
    • Sort by: Expiration date (ascending - soonest expiration first)
    • Display columns: Certificate Common Name (CN), Subject Alternative Names (SAN), Issuer, Expiration date, Days remaining, Last alert severity

  3. Export to Excel for renewal planning:

    • Monitor View → Export button → Excel format
    • Operations team reviews quarterly: Identify certificates expiring in next 90 days, schedule renewals with PKI team, track renewal completion status

Alert Email Example

When certificate approaches 90-day threshold, operations team receives email:

Subject: DataPower Certificate Renewal Required - 90 days remaining

Body:

Alert: DataPower certificate expiring soon
Appliance: Prod-Primary
Domain: TradingPartner
Certificate Common Name: partner-a.example.com
Subject Alternative Names: api.partner-a.com, edi.partner-a.com
Issuer: DigiCert Secure Server CA
Valid Until: 2024-10-15 23:59:59 UTC
Days Remaining: 87 days

Action Required:
1. Contact PKI team to initiate certificate renewal request
2. Provide Certificate Signing Request (CSR) with updated SANs
3. Test renewed certificate in Dev environment before production deployment
4. Schedule production deployment during next maintenance window (Saturday 2-6 AM)

Scenario: E-Commerce Certificate Outage Prevention

Challenge: E-commerce company with 147 TLS certificates across 8 DataPower appliances (API gateways, payment gateways, partner EDI connections). Manual tracking in Excel spreadsheet failed when operations engineer on vacation.

Problem:

  • Nov 14, 2023: TLS certificate for payment gateway expired (CN=payments.retailer.com)
  • Customer payment authorizations failed (HTTPS handshake error: certificate expired)
  • Revenue impact: $85K lost sales during 6-hour outage (Black Friday preparation week)
  • Remediation cost: $25K emergency certificate renewal + Saturday overtime for 8 engineers

Solution:

  • Configured SNMP certificate expiration monitoring with 90/30/7 day thresholds
  • Created "DataPower Certificate Dashboard" Monitor View sorted by expiration date
  • Scheduled quarterly certificate renewal reviews (operations team + PKI team + application owners)

Results:

  • Zero certificate expiration outages since implementation (18 months)
  • $85K revenue protection (no payment gateway downtime)
  • $25K emergency cost avoidance (no emergency weekend renewals)
  • 147 certificates monitored continuously with proactive 90-day renewal alerts

Next Steps

  1. Deploy & Configure: Set up SNMP notification rules on your DataPower appliances following Step 1-3 above
  2. Create Alerts: Configure threshold-based alerts in Nodinite (Warning <90, Error <30, Critical <7 days)
  3. Monitor Dashboard: Create a Certificate Dashboard Monitor View for your operations team
  4. Quarterly Reviews: Schedule quarterly certificate renewal reviews with PKI team and application owners
