OpenTelemetry Logs

The OpenTelemetry plugin by Netdata makes viewing, exploring and analyzing OpenTelemetry logs simple and efficient.

It receives OTLP-formatted log data and indexes it for fast querying. The logs are explored from the "Logs" tab of the Netdata UI, using the same powerful exploration interface used for systemd journal logs.

Visualization

You can start exploring OpenTelemetry logs on the "Logs" tab of the Netdata UI.

Key features

• Views logs ingested via OpenTelemetry OTLP/gRPC protocol.
• Allows filtering on any log field or field value, for any time-frame.
• Allows full text search (grep) on all log fields, for any time-frame.
• Provides a histogram for log entries over time, with a breakdown per field-value, for any field and any time-frame.
• Uses fast indexed lookups with pre-built indexes for performance.
• Supports faceted search across log fields (severity, hostname, service, etc.).
• In PLAY mode shows new log entries immediately after they are received.

Setup

Prerequisites

• A Netdata Cloud account (the otel-logs view is access-gated and requires a Netdata Cloud sign-in).
• The otel.plugin enabled, with its OTLP/gRPC endpoint configured in otel.yaml (see the plugin's README).
• An OpenTelemetry exporter (an OTel Collector or an SDK) pointed at that endpoint to send OTLP logs.

Configuration

There is no configuration needed for this integration.
