# 'receivers' specify configurations of receivers.
# See the README for more information about the receivers available for configuration.
receivers:
  # The hostmetrics receiver; this configuration will get cpu load metrics about the machine
  # the agent is running on every minute.
  # For more information on configuring the hostmetrics receiver, refer to the documentation here:
  # https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/hostmetricsreceiver
  hostmetrics:
    collection_interval: 1m
    scrapers:
      # Theses scrapers work on all operating systems
      load:
      filesystem:
      memory:
      network:
      # Remove these scrapers for macOS agents as they are not supported and will generate errors in the logs
      cpu:
      disk:

  # The syslog receiver; this configuration will listen on every network interface on port 514
  # for UDP syslog messages using the rfc3164 protocol.
  # For more information on configuring the syslog receiver, refer to the documentation here:
  # https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/syslogreceiver
  # syslog:
  #   protocol: "rfc3164"
  #   udp:
  #     listen_address: 0.0.0.0:514

# 'processors' specify configurations of processors.
# See the README for more information about the processors available for configuration.
processors:
  # The batch processor; This processor will aggregate incoming metrics into a batch, releasing them if
  # a certain time has passed or if a certain number of entries have been aggregated.
  # For more information on configuring the batch processor, refer to the documentation here:
  # https://github.com/open-telemetry/opentelemetry-collector/tree/main/processor/batchprocessor
  batch:

# 'exporters' specify configurations for certain exporters.
# See the README for more information on the exporters available for configuration.
exporters:
  # The logging exporter; This exporter logs to stdout.
  # For more information on configuring the logging exporter, refer to the documentation here:
  # https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/loggingexporter
  logging:
    verbosity: detailed

# 'service' specifies how to construct the data pipelines using the configurations above.
service:
  pipelines:
    # 'metrics' specifies a metrics pipeline; metrics are scraped using the 'hostmetrics' receiver,
    # which are aggregated into batches by the 'batch' processor,
    # and are exported using the 'logging' exporter, printing the metrics to stdout.
    metrics:
      receivers: [hostmetrics]
      processors: [batch]
      exporters: [logging]

    # `logs` specifies the logging pipeline; logs are received using the 'syslog' receiver,
    # which are then aggregated into batches by the 'batch' processor,
    # and are exported using the 'logging' exporter, printing the logs to stdout.
    # Both the batch configuration and logging configuration may be shared between the logs pipeline and
    # the metrics pipeline, as shown in this example.
    # logs:
    #   receivers: [syslog]
    #   processors: [batch]
    #   exporters: [logging]
