This curriculum spans the technical breadth of a multi-workshop program on ELK data ingestion, covering architecture planning, pipeline optimization, security hardening, and scalability engineering comparable to an internal capability build for large-scale log management.

Module 1: Understanding ELK Stack Architecture and Data Flow

  • Evaluate the role of each ELK component (Elasticsearch, Logstash, Kibana) in handling data ingestion and determine which components are mandatory based on data source and use case.
  • Design cluster topology (data, ingest, master nodes) to support expected data volume and query load during import operations.
  • Configure network ports and firewall rules to allow secure communication between Beats, Logstash, and Elasticsearch nodes.
  • Select appropriate transport protocols (HTTP, TCP, TLS) for data transmission based on security and performance requirements.
  • Assess the impact of sharding and replication settings on ingestion throughput and recovery time during bulk imports.
  • Implement health checks and monitoring for each ELK service to detect failures during data import pipelines.
  • Determine whether to use centralized Logstash or lightweight Beats based on resource constraints and data preprocessing needs.

Module 2: Data Source Identification and Classification

  • Classify data sources by structure (structured, semi-structured, unstructured) and update frequency (real-time, batch, event-driven) to inform ingestion strategy.
  • Map application logs, system metrics, and database exports to appropriate Beats (Filebeat, Metricbeat, Auditbeat) or custom Logstash inputs.
  • Identify sensitive data elements (PII, credentials) during source analysis to enforce early-stage masking or filtering.
  • Document schema expectations and field naming conventions per data source to ensure consistency across indices.
  • Assess log rotation policies on source systems to configure Filebeat harvesting settings (close_inactive, clean_inactive).
  • Validate timestamp formats across heterogeneous sources to prevent misalignment in Kibana time-series views.
  • Inventory third-party APIs and their rate limits when planning data pull intervals via Logstash HTTP input.

Module 3: Logstash Pipeline Configuration and Optimization

  • Structure Logstash configuration files into input, filter, and output sections with conditional logic for multi-source pipelines.
  • Use mutate and dissect filters to parse unstructured logs instead of grok when performance is critical and patterns are predictable.
  • Configure pipeline workers and batch sizes based on CPU core count and input throughput to avoid backpressure.
  • Implement dead-letter queues for failed events to enable post-failure analysis without data loss.
  • Use persistent queues on disk to prevent data loss during Logstash restarts or crashes.
  • Minimize filter complexity by offloading enrichment (e.g., GeoIP lookups) to ingest nodes in Elasticsearch when feasible.
  • Test pipeline performance using Logstash’s --config.test_and_exit and benchmark with sample production data.

Module 4: Filebeat and Metricbeat Deployment Strategies

  • Configure Filebeat prospectors to monitor specific log paths and exclude irrelevant files using ignore_older and close_eof settings.
  • Enable TLS encryption between Filebeat and Logstash or Elasticsearch to meet compliance requirements for data in transit.
  • Use Filebeat modules for common services (Nginx, MySQL) to leverage prebuilt parsers and dashboards, then customize as needed.
  • Set up Metricbeat to collect system and service metrics at defined intervals, adjusting period and metricsets per host load.
  • Manage Filebeat registry file size and cleanup to prevent disk exhaustion on long-running hosts.
  • Deploy Beats using configuration management tools (Ansible, Puppet) for consistent rollout across large fleets.
  • Configure output load balancing and failover to multiple Logstash instances or Elasticsearch nodes.

Module 5: Schema Design and Index Management

  • Define custom index templates with appropriate mappings to enforce data types and avoid dynamic mapping issues.
  • Use index aliases to decouple applications from physical index names, enabling rollover and reindexing operations.
  • Implement Index Lifecycle Management (ILM) policies to automate rollover, shrink, and deletion based on size or age.
  • Set up time-based indices (e.g., logs-2024-04-01) with daily or weekly rotation aligned with retention policies.
  • Prevent field mapping conflicts by validating new data against existing templates before full deployment.
  • Optimize keyword vs. text field usage in mappings based on search and aggregation requirements.
  • Estimate shard count per index based on data volume and retention to avoid oversized or undersized shards.

Module 6: Data Transformation and Enrichment

  • Use Logstash mutate filters to rename, remove, or convert fields to align with organizational naming standards.
  • Integrate external reference data (e.g., IP-to-location, user lookup tables) using Logstash JDBC or CSV filters.
  • Apply conditional filtering to drop irrelevant events (e.g., health checks, 200 status codes) before indexing.
  • Normalize timestamps into @timestamp field using date filters with multiple format fallbacks.
  • Flatten nested JSON structures to improve query performance and reduce index overhead.
  • Mask or remove sensitive fields (e.g., credit card numbers) using gsub or ruby filters prior to transmission.
  • Enrich events with static metadata (environment, region, team) using Logstash add_field directives.

Module 7: Security and Access Control in Data Ingestion

  • Configure Elasticsearch API keys or service accounts for Beats and Logstash instead of shared user credentials.
  • Enable Role-Based Access Control (RBAC) to restrict index creation and write permissions to specific ingestion roles.
  • Encrypt configuration files containing passwords using Elasticsearch keystore and reference values via ${} syntax.
  • Validate certificate chains when using TLS between Beats and Logstash to prevent man-in-the-middle attacks.
  • Audit ingestion pipeline changes using version control and change management processes.
  • Restrict Logstash plugin installations to approved sources to prevent malicious code execution.
  • Monitor for unauthorized index creation attempts or spikes in document ingestion rates.

Module 8: Monitoring, Troubleshooting, and Performance Tuning

  • Instrument Logstash with monitoring APIs to track event throughput, queue depth, and filter performance.
  • Analyze Elasticsearch ingest node CPU and memory usage to identify bottlenecks in pipeline processing.
  • Use Kibana’s Stack Monitoring to correlate ingestion delays with cluster health and resource saturation.
  • Interpret Filebeat logging output to diagnose harvester and publisher errors during log collection.
  • Adjust Logstash pipeline batch size and workers when event processing latency exceeds SLA thresholds.
  • Diagnose backpressure by examining Elasticsearch thread pool rejections and queue sizes.
  • Use Elasticsearch _bulk API response codes to detect indexing failures and implement retry logic.

Module 9: Scalability and High Availability Planning

  • Deploy multiple Logstash instances behind a load balancer to distribute ingestion load and eliminate single points of failure.
  • Configure Filebeat to use load-balanced outputs with sticky connections to maintain event ordering when required.
  • Size Elasticsearch ingest nodes separately from data nodes to isolate processing impact.
  • Plan for regional data collection by deploying edge Logstash instances and aggregating to central clusters.
  • Test failover scenarios by simulating Logstash node outages and verifying Beats’ retry behavior.
  • Scale index shard count and replica settings based on projected write volume and read query concurrency.
  • Implement automated pipeline deployment using CI/CD to ensure configuration consistency across environments.
