What is this?

Logging captures structured events — who did what, when, and outcome — for troubleshooting and audit.

Why should you care?

CloudVerse centralizes logs from apps, K8s, and firewalls into one searchable store.

See it live — copy this example

Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.

# Fluent Bit → Log Analytics (CloudVerse)
apiVersion: v1
kind: ConfigMap
metadata:
  name: fluent-bit-config
data:
  fluent-bit.conf: |
    [INPUT]
        Name              tail
        Path              /var/log/containers/*payments*.log
    [OUTPUT]
        Name              azure
        Match             *
        Workspace_Id      ${WORKSPACE_ID}
        Shared_Key        ${SHARED_KEY}

What happened?

  • Use structured JSON logs with correlation IDs.
  • Retention and immutability matter for compliance.

Practice next

  1. Add JSON logging to one API.
  2. Ship container logs to central workspace.
  3. Search by correlationId.
  4. Add audit log stream for admin actions.
  5. Enable log immutability vault.

Remember

Structured logs. Central aggregation. Correlation IDs.

Outcome: correlationId finds API + DB logs in one query.
