OpenSearch Tackles Alert Sprawl With PPL and Unified Manager

Observability at enterprise scale presents a difficult choice: monitor comprehensively and face exponential bills, or constrain monitoring scope and accept operational blind spots. This hands-on session targets SREs and platform engineers struggling with runaway alert rules, alert fatigue from false positives, and fragmented notification systems. Two OpenSearch features—PPL (Piped Processing Language) and the Unified Alert Manager—directly solve these challenges, and both operate under Apache 2.0 licensing with no feature tiers, no licensing overhead, and no cost ceiling that makes alerting uneconomical.

Charles Humble, host at The New Stack, and Joshua Bright, an OpenSearch project maintainer at Amazon, will demonstrate both the technical design and day-to-day operational use of these tools. The session includes live Q&A for participants to pose their own alerting challenges.

What the Session Covers

• Building multi-step alert conditions through PPL's pipeline syntax—and seeing how cross-signal correlation detects failure modes that simple threshold alerts cannot
• Setting up the Unified Alert Manager for centralized rule management, alert routing, and alert suppression—and how this operational shift affects on-call rotations
• Creating cross-signal alert conditions that join logs, metrics, and traces in a single query without integrating multiple separate platforms
• Lowering false positive rates while preserving signal detection—using concrete suppression techniques where the most leverage exists
• Running OpenSearch alerting without a pricing ceiling: the practical implications of no feature restrictions on ingestion volume and alert rule scaling
