# OpenTelemetry Collector — Mezmo OTLP forwarder

#

# Chart:  open-telemetry/opentelemetry-collector

# Install:

#   helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts

#   helm repo update

#   helm upgrade --install otel-collector open-telemetry/opentelemetry-collector \

#     -n otel --create-namespace -f values.yaml

#

# What this does:

#   - Runs as a DaemonSet so every node tails /var/log/pods/*/*/*.log

#   - Exposes a ClusterIP Service at

#       otel-collector-opentelemetry-collector.otel.svc.cluster.local

#     accepting OTLP/gRPC (4317) and OTLP/HTTP (4318) for logs, metrics, traces

#   - Forwards everything to https://logs.use.dev.mezmo.it/otel via otlphttp

mode: daemonset

# contrib distribution — required for filelog, k8sattributes, etc.

image:... 

  # tag: "0.115.0"   # pin to a known-good release

# Stable in-cluster endpoint for other workloads to send OTLP to.

service:... 

# Trim chart-default ports we don't use; keep OTLP gRPC + HTTP.

ports:... 

resources:... 

# Pull the Mezmo ingestion key from the `mezmo-otlp` Secret (see secret.yaml).

extraEnvs:... 

# Presets do the Kubernetes plumbing for us:

#   logsCollection       -> mounts /var/log/pods, adds filelog receiver, wires it into the logs pipeline

#   kubernetesAttributes -> creates RBAC + adds k8sattributes processor to every pipeline
