🚀 IV. Installing OpenTelemetry Collector: Kick-start Your Data Monitoring Journey

In this section, we will guide you on how to easily install OpenTelemetry Collector across different platforms! Whether you’re using Docker, Kubernetes, or directly installing it on your operating system, it’s all quite straightforward! 😊

🐳 Docker

For Docker users, installation and configuration require just a few simple commands.

1. Pull the Docker image: First, use the command below to pull the OpenTelemetry Collector image from Docker Hub. Remember to replace 0.116.1 with the version you need!

   docker pull otel/opentelemetry-collector-contrib:0.116.1
   docker run otel/opentelemetry-collector-contrib:0.116.1
   

   These two commands respectively download the image locally using docker pull and start the image as a container with docker run. Simple and quick! 👍

2. Load Custom Configuration: If you need to use a custom configuration file, you can load it into the container using the command below.

   docker run -v $(pwd)/config.yaml:/etc/otelcol-contrib/config.yaml otel/opentelemetry-collector-contrib:0.116.1
   

   The -v option is used to mount your local path to the specified path inside the container, with $(pwd)/config.yaml representing the config.yaml file in your current working directory. This way, the Collector can seamlessly use your custom configuration! 📂

📦 Docker Compose

If you prefer using Docker Compose to manage applications, here’s how to easily add OpenTelemetry Collector in docker-compose.yaml:

otel-collector:
  image: otel/opentelemetry-collector-contrib
  volumes:
    - ./otel-collector-config.yaml:/etc/otelcol-contrib/config.yaml
  ports:
    - 1888:1888 # pprof extension
    - 8888:8888 # Prometheus metrics exported by the Collector
    - 8889:8889 # Metrics from the Prometheus exporter
    - 13133:13133 # health_check extension
    - 4317:4317 # OTLP gRPC receiver
    - 4318:4318 # OTLP HTTP receiver
    - 55679:55679 # zpages extension

Here, we define an otel-collector service and set up multiple port mappings so external services can access the performance metrics collected by the Collector. With this configuration file, you can easily start and stop your Collector container! 😃

🐙 Kubernetes

If your application runs in a Kubernetes cluster, you can quickly deploy OpenTelemetry Collector with the command below:

kubectl apply -f https://raw.githubusercontent.com/open-telemetry/opentelemetry-collector/v0.116.1/examples/k8s/otel-config.yaml

This command will download the example configuration from GitHub and apply it to your Kubernetes cluster. It’s perfect for beginners looking to get started quickly, so give it a try! 📈

🐧 Linux

For Linux users, you can choose to install via DEB or RPM packages. Here are the specific commands:

DEB Installation

On Debian systems, execute the following commands to install:

# For AMD64
sudo apt-get update
sudo apt-get -y install wget
wget https://github.com/open-telemetry/opentelemetry-collector-releases/releases/download/v0.116.1/otelcol_0.116.1_linux_amd64.deb
sudo dpkg -i otelcol_0.116.1_linux_amd64.deb

In these commands, wget is used to download the specific DEB package, while dpkg is used for installation. Ensure you are connected to the internet! 🌐

RPM Installation

On Red Hat systems, you can use the following commands for installation:

# For AMD64
sudo yum update
sudo yum -y install wget systemctl
wget https://github.com/open-telemetry/opentelemetry-collector-releases/releases/download/v0.116.1/otelcol_0.116.1_linux_amd64.rpm
sudo rpm -ivh otelcol_0.116.1_linux_amd64.rpm

These steps ensure that the Collector is installed on your Red Hat system, specifically for AMD64 architecture. 🛠️

🍏 macOS

macOS users can also easily install OpenTelemetry Collector, here are the commands for extracting and installing:

# For Intel
curl --proto '=https' --tlsv1.2 -fOL https://github.com/open-telemetry/opentelemetry-collector-releases/releases/download/v0.116.1/otelcol_0.116.1_darwin_amd64.tar.gz
tar -xvf otelcol_0.116.1_darwin_amd64.tar.gz

At this step, use curl to download the Collector and tar -xvf to extract it. Give it a shot! 💻

💻 Windows

Windows users can install by downloading the gzipped tarball. After downloading, extract the files and run otelcol.exe to start the service easily. This process is very simple, just follow the standard extraction steps and enjoy running OpenTelemetry Collector on Windows 🍔.

⚙️ V. Sample Configuration: Build Your Data Processing Pipeline

After installation, configuring OpenTelemetry Collector’s behavior is essential! Here’s a simple yet practical configuration example:

receivers:
  otlp:
    protocols:
      grpc: {}
      http: {}

processors:
  batch:

exporters:
  logging:
    logLevel: debug

service:
  pipelines:
    traces:
      receivers: [otlp]
      processors: [batch]
      exporters: [logging]

In this configuration, we first set up an OTLP receiver that supports both gRPC and HTTP protocols. Next, we utilize the batch processor to optimize the processing flow. Finally, we export the results via the logging exporter as debug logs for easier troubleshooting and verification 📝.

We hope these steps help you successfully install and configure OpenTelemetry Collector, embarking on your exciting observability journey! 📊
