Grafana Alloy Has a Free OpenTelemetry Collector — Replace Prometheus Agent and Fluentd in One Tool

Grafana Alloy Has a Free OpenTelemetry Collector You run Prometheus for metrics, Fluentd for logs, Jaeger agent for traces. Three agents on every server. Grafana Alloy replaces all three with one binary. What Alloy Does Grafana Alloy (formerly Grafana Agent) is a vendor-agnostic OpenTelemetry collector: Metrics — scrape Prometheus endpoints, push to Mimir/Prometheus Logs — tail files, parse, send to Loki Traces — receive OTLP, send to Tempo/Jaeger Profiles — continuous profiling with Pyroscope Single binary — one agent for all telemetry types River configuration — programmable, type-safe config language Quick Start // alloy config prometheus.scrape "default" { targets = [{"__address__" = "localhost:8080"}] forward_to = [prometheus.remote_write.mimir.receiver] } prometheus.remote_write "mimir" { endpoint { url = "http://mimir:9009/api/v1/push" } } loki.source.file "logs" { targets = [{"__path__" = "/var/log/*.log"}] forward_to = [loki.write.default.receiver] } loki.write "default" { end
