Host data enrichments

Host metrics

The OpenTelemetry agent includes a built-in hostMetrics preset, which is enabled by default. This gives you:

• CPU, memory, disk, and network metrics from your hosts, including AWS EC2 instances and Azure Virtual Machines
• Visibility into system health without any additional setup

Extended metrics with AWS CloudWatch

For deeper metrics coverage, use the AWS CloudWatch Metrics Connector:

• Metrics are pulled every 10 minutes by default (adjustable for cost control)
• Metric definitions and tags are refreshed every 5 minutes
• Ideal for compliance, auditing, or environments with scale constraints

For near real-time updates, switch to a Firehose-based integration.

Note

AWS CloudWatch Metric ingestion counts toward your usage quota.

Host process

To see which processes are running on your hosts, enable this manually in your OpenTelemetry agent configuration:

hostMetrics:
  enabled: true
  process:
    enabled: true  # Enables collection of host processes

Next steps

Ensure your instrumented applications forward telemetry to the Coralogix agent by following Configure applications to send telemetry.
