Serverless Pipeline: FSx for ONTAP Logs to 9 Observability Backends
An AWS Builders technical article describes a single serverless architecture that ships Amazon FSx for ONTAP audit logs to nine observability platforms (Datadog, New Relic, Splunk, Grafana Cloud, Elastic, Dynatrace, Sumo Logic, Honeycomb, and an OTel Collector path). The team validated CloudFormation templates across 12 articles and three event sources, documented vendor-specific batch limits and auth models, and measured a ~90% AWS cost reduction versus an EC2-based collector. Key operational patterns include a 5-minute EventBridge Scheduler poll (due to FSx S3 Access Point limitations), checkpoint-after-delivery, credential caching with reload-on-401, a reserved concurrency of 1, and KMS-encrypted DLQs. The post recommends starting with an OTLP/OTel Collector path for multi-vendor evaluation and pins tested OTel Collector Contrib version v0.152.0. Publication date: 2026-05-31.
Practical, validated serverless architecture and multi-vendor integration guidance reduces operational cost and vendor lock-in for telemetry pipelines; highlights a persistent platform limitation (FSx S3 AP lacks event notifications) that affects ingestion design choices.

Key Takeaways & Evidence Grounding
- Built and E2E-verified a serverless architecture shipping FSx for ONTAP audit logs to nine observability platforms from one codebase.
- Reported ~90% monthly AWS cost reduction versus EC2-based collectors (~$66 → $5–8) for 10 GB/month telemetry ingestion.
- As of May 2026, FSx for ONTAP S3 Access Points do not support S3 Event Notifications; architecture uses a 5-minute EventBridge Scheduler poll.
- Only vendor-specific formatting + HTTP call changed across integrations; shared components include S3 AP access, checkpointing (SSM), DLQ (KMS), credential caching (Secrets Manager) and retry logic.
- OpenTelemetry (OTLP) recommended as a universal format; OTel Collector Contrib v0.152.0 was the verified collector build used in testing.

Serverless FSx for ONTAP Logs to Datadog Integration
This technical guide describes a serverless pattern to deliver FSx for ONTAP audit logs into Datadog Log Explorer. The solution deploys a single CloudFormation stack that provisions a Lambda function, EventBridge Scheduler, DLQ (SQS), IAM roles, CloudWatch alarms and a dashboard. The Lambda lists objects from an FSx for ONTAP S3 Access Point, reads EVTX/XML audit files, normalizes events, batches them within Datadog Logs API v2 limits, and ships with exponential backoff and jitter. Checkpoint semantics ensure the pipeline is at-least-once (checkpoint advances only after all batches succeed). The post includes Datadog field mappings, operational validation steps, troubleshooting notes (eg. VPC / S3 AP timeouts, gzip issue on AP1), day‑2 replay/reset procedures, and a cost estimate (~$2/month without VPC, ~$30–50+/month with VPC/NAT for a typical small deployment).
AI-Powered Metadata Catalog for FSx for ONTAP
An AWS Builders technical PoC demonstrates an AI-powered metadata catalog pattern that keeps raw unstructured files on FSx for ONTAP while storing queryable Iceberg metadata in S3 Tables. The verified AWS-native path (Athena + S3 Tables + Bedrock + OpenSearch + Lake Formation) completed an end-to-end demo in 42 seconds and cost $0.07 for the demo. The pattern uses Amazon Bedrock for AI classification and Titan embeddings for vector search (OpenSearch Serverless kNN). It substantially reduces discovery time (minutes–hours to <2 seconds at scale) and eliminates the need to bulk-copy raw files to S3, producing material projected cost savings versus full S3 copies. The article documents cross-platform compatibility tests (Databricks, Snowflake), governance via Lake Formation, known limitations, and operational considerations for production deployment.
Java Observability Pipeline: Metrics, Logs, Traces Guide
A technical guide that breaks Java observability into a four-phase pipeline: instrumentation, agents/collectors, storage backends, and visualization. The article maps common tools to each phase (e.g., Micrometer/OpenTelemetry and SLF4J/Logback for instrumentation; OpenTelemetry Collector and Grafana Alloy as universal routers; Prometheus/Mimir/Datadog for metrics; Tempo/Zipkin/Jaeger for traces; Loki/OpenSearch/Elasticsearch for logs; Grafana for unified visualization). It discusses push vs pull models (Prometheus scrapes/pull; Mimir/Datadog use push), practical workflows for metric/trace/log journeys, and architectural trade-offs when choosing the LGTM integrated stack versus custom best-of-breed stacks (Prometheus, Zipkin, OpenSearch, Fluent Bit). The guide emphasizes decoupling business logic from backend storage so backends can be swapped without changing application code.
