AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
Grafana Alloy is an OpenTelemetry-compatible collector that uses a unified configuration language to build telemetry pipelines. This skill provides guidance on using the Alloy CLI, configuring components for data collection and shipping, and managing pipelines for metrics, logs, traces, and profiles. It covers the Alloy configuration syntax, component discovery, relabeling, and integration with backends like Grafana Cloud, Prometheus, Loki, Tempo, and Pyroscope.
What it does
- Provides syntax and structure for config.alloy files using blocks and component references.
- Explains how to use discovery components for Kubernetes, Docker, and cloud infrastructure.
- Details the configuration of exporters and receivers for metrics, logs, and traces.
- Offers commands for validating and formatting configuration files.
- Describes how to use the Alloy UI to monitor component health and data flow.
- Covers advanced features like modules, clustering, and remote configuration management.
When to use it
- When setting up a telemetry pipeline to collect and ship observability data.
- When migrating from Grafana Agent or OpenTelemetry Collector to Alloy.
- When configuring scrape targets for Kubernetes pods or other infrastructure.
- When debugging issues with data ingestion or pipeline connectivity.
- When needing to transform or drop specific logs or metrics before they are shipped.
Advantages
- Unified binary for handling multiple telemetry signals.
- Native support for OpenTelemetry and Prometheus protocols.
- Built-in validation and formatting tools to ensure configuration correctness.
- Extensive component library for service discovery and data routing.
- Integrated web UI for inspecting component status and troubleshooting.
Usage examples
- “How do I set up a basic Prometheus scrape job in Alloy?”
- The agent provides a configuration block using prometheus.scrape to target an address and forward metrics to a remote_write component.
- “Help me debug why my Alloy logs aren't appearing in Loki.”
- The agent suggests checking the component health via the local UI at port 12345 and verifying the loki.source.file configuration.
- “How do I validate my config.alloy file?”
- The agent instructs to run the alloy validate command to perform a syntax check on the configuration file.
- “Write a configuration to receive OTLP traces and send them to Tempo.”
- The agent provides an otelcol.receiver.otlp block connected to an otelcol.exporter.otlp block with appropriate authentication.

Grafana Alloy
OpenTelemetry-compatible collector — one binary for metrics + logs + traces + profiles.
Prerequisites
alloyCLI installed (brew install grafana/grafana/alloy,apt install alloy, orgrafana/alloyDocker image)An endpoint to ship to (Grafana Cloud, Prometheus, Loki, Tempo, Pyroscope)
API key + username for that endpoint, exported as
GRAFANA_API_KEYetc.
Common Workflows
1. Write + validate a config locally
// config.alloy — metrics → Grafana Cloud
prometheus.scrape "app" {
targets = [{"__address__" = "localhost:9090"}]
forward_to = [prometheus.remote_write.cloud.receiver]
scrape_interval = "30s"
}
prometheus.remote_write "cloud" {
endpoint {
url = sys.env("PROMETHEUS_URL")
basic_auth {
username = sys.env("PROM_USER")
password = sys.env("GRAFANA_API_KEY")
}
}
}# 1. Format + syntax-check (catches typos before run)
alloy fmt config.alloy
alloy validate config.alloy
# 2. Run it
alloy run config.alloy
# or as a service: systemctl restart alloy
# 3. Verify all components are healthy via the UI on port 12345
curl -s http://localhost:12345/api/v0/web/components \
| jq '.[] | select(.health.state != "healthy") | {id, state:.health.state, msg:.health.message}'
# Expect: empty (nothing unhealthy). Otherwise the row shows the failing component + reason.
# 4. Verify samples are flowing
curl -s http://localhost:12345/metrics \
| grep -E '^prometheus_remote_storage_(samples_total|enqueue_retries_total)' | head
# samples_total should be > 0 and rising; retries should be 0.2. Add log shipping (file → Loki)
loki.source.file "app_logs" {
targets = [{ __path__ = "/var/log/app/*.log", job = "app" }]
forward_to = [loki.write.cloud.receiver]
}
loki.write "cloud" {
endpoint {
url = sys.env("LOKI_URL")
basic_auth {
username = sys.env("LOKI_USER")
password = sys.env("GRAFANA_API_KEY")
}
}
}# Verify in Grafana → Explore → Loki:
# {job="app"}
# Expect lines streaming. If empty:
# - check /var/log/app/*.log actually exists + readable by the alloy user
# - http://localhost:12345 → loki.source.file.app_logs → "Targets" tab3. Receive OTLP traces and ship to Tempo
otelcol.receiver.otlp "default" {
grpc { endpoint = "0.0.0.0:4317" }
http { endpoint = "0.0.0.0:4318" }
output { traces = [otelcol.exporter.otlp.tempo.input] }
}
otelcol.exporter.otlp "tempo" {
client {
endpoint = "tempo-xxx.grafana.net/tempo:443"
auth = otelcol.auth.basic.grafana_cloud.handler
}
}
otelcol.auth.basic "grafana_cloud" {
username = sys.env("TEMPO_USER")
password = sys.env("GRAFANA_API_KEY")
}# Verify in Grafana → Explore → Tempo → service.name = your-service
# At the Alloy level, watch the receiver:
curl -s http://localhost:12345/metrics | grep otelcol_receiver_accepted_spansFull pattern set (Kubernetes discovery + relabel, complete Cloud pipeline for all 4 signals): references/collection-patterns.md.
