    • Health Score metrics

  • Study alert rules:

    • CPU, memory, connections, VS down, pool member failure
  • Configure alert channels:

    • Email (SMTP)

    • SNMP traps

    • Webhooks or REST callbacks

  • Simulate an alert setup where a pool member failure notifies both SNMP and webhook endpoints

Day 4 – Logging and Analytics Configuration

Goal: Forward logs to external platforms and manage log storage settings.

Tasks:

  • Configure real-time log streaming:

    • HTTP logs

    • Health monitor logs

    • System event logs

  • Study integration with:

    • Syslog

    • Kafka

    • Logstash / Elasticsearch

    • vRealize Log Insight

  • Set log retention policies and log export options

  • Create a mock architecture where Avi → Kafka → ELK is used for centralized observability

  • Document the retention rules for each log type

Day 5 – Automation via API, SDK, and Tools

Goal: Understand and implement automation for operational workflows.
