OpenTelemetry Collector Processors

Resource Detection Processor

The resourcedetection processor can be used to detect resource information from the host and append or override the resource value in telemetry data with this information.

By default, the hostname is set to the FQDN if possible, otherwise, the hostname provided by the OS is used as a fallback. This logic can be changed from using using the hostname_sources configuration option. To avoid getting the FQDN and use the hostname provided by the OS, we will set the hostname_sources to os.

processors:
  batch:
  resourcedetection/system:
    detectors: [system]
    system:
      hostname_sources: [os]

If the workshop instance is running on an AWS/EC2 instance we can gather the following tags from the EC2 metadata API (this is not available on other platforms).

• cloud.provider ("aws")
• cloud.platform ("aws_ec2")
• cloud.account.id
• cloud.region
• cloud.availability_zone
• host.id
• host.image.id
• host.name
• host.type

We will create another processor to append these tags to our metrics.
