OpenTelemetry using Docker

This tutorial demonstrates configuring OpenTelemetry (OTEL) Collector to send your logs and metrics to Coralogix using Docker.

Prerequisites

• Docker installed

Configuration

STEP 1. Create a configuration file. Copy this template file and save it as config.yaml.

receivers:
  filelog:
    start_at: beginning
    include:
      - /example.log
    include_file_path: true
    multiline: {line_start_pattern: "\\n"}
	hostmetrics:
	    collection_interval: 30s
	    scrapers:
	      cpu:
	      memory:
exporters:
  coralogix:
    domain: "Domain"
    private_key: "Private key"
    application_name: "Application Name"
    subsystem_name: "Subsystem Name"
    timeout: 30s

service:
  pipelines:
    logs:
      receivers: [ filelog ]
      exporters: [ coralogix ]
    metrics:
      receivers: [ hostmetrics ]
      exporters: [ coralogix ]

Provide the following variables.

STEP 2. Save this log file as example.log.

2023-06-19 05:20:50 ERROR This is a test error message
2023-06-20 12:50:00 DEBUG This is a test debug message
2023-06-21 12:34:56 INFO This is a test info message

STEP 3. Pull a docker image and run the collector in a container. To load your custom configuration config.yaml and the log file example.log from your current working directory, mount the files as a volume into the container. Find out more here.

docker pull otel/opentelemetry-collector-contrib
docker run -d -v "$(pwd)"/config.yaml:/etc/otelcol-contrib/config.yaml -v "$(pwd)"/example.log:/example.log otel/opentelemetry-collector-contrib

Validation
