ElastAlert 2 is a standalone Python tool that runs rule-based alerting on anomalies, spikes, and patterns in data stored in Elasticsearch or OpenSearch. It is a maintained community continuation of Yelp's original ElastAlert, deployable via Docker or a Helm chart on Kubernetes.

Use cases

• alert on error log spikes in elasticsearch
• get notified when a specific pattern appears in opensearch logs
• run scheduled anomaly detection queries against elasticsearch
• send slack or email alerts when log thresholds are exceeded
• replace yelp elastalert with a maintained fork
• deploy log alerting as a kubernetes microservice

When to choose

• you already store logs or metrics in Elasticsearch or OpenSearch and need rule-based alerting
• you have existing ElastAlert rules and want a maintained, backwards-compatible continuation
• you want a containerized alerting microservice with a Helm chart for Kubernetes

When to avoid

• your data lives in a database other than Elasticsearch or OpenSearch
• you need full observability suites with dashboards rather than a focused alerting tool
• you want real-time streaming alerting with sub-second latency
