About ElastAlert 2
ElastAlert 2 continues the original yelp/elastalert project. It runs as a standalone service that queries Elasticsearch or OpenSearch on a schedule and sends notifications when the data matches rules you write, such as a spike in errors, a missing heartbeat or a new value in a field.
The repository includes a Dockerfile, a Helm chart for Kubernetes, example rules and documentation. It suits teams that already keep logs or metrics in Elasticsearch or OpenSearch and want rule-based alerts without a commercial alerting add-on.
