## What it is
Sensu Go is an open-source, agent-based monitoring and observability pipeline for ephemeral infrastructure and distributed applications, rewritten in Go with an embedded etcd datastore. It collects service health checks and telemetry via a publish-subscribe model, routes events through filters and handlers, and integrates with tools like Prometheus, Splunk, PagerDuty, and Elasticsearch.

## Use cases
- monitor server health across multi-cloud infrastructure
- alert on service failures in distributed systems
- collect metrics from ephemeral cloud instances
- monitor kubernetes clusters
- automate incident notifications with pagerduty or slack
- replace nagios with a scalable monitoring system
- monitoring as code with infrastructure automation

## When to choose
- you need scalable monitoring for dynamic, ephemeral cloud or Kubernetes environments
- you want monitoring-as-code workflows with self-service APIs
- you need to consolidate multiple monitoring tools into one observability pipeline
- you want an agent-based system with auto-discovery and extensible plugins

## When to avoid
- you only need simple single-host uptime checks
- you want a fully free solution beyond 100 nodes without commercial licensing
- you need a turnkey UI out of the box - the web UI is a separate standalone product
- you prefer lightweight push-based metrics without an agent footprint
