Jaeger (core)

The Jaeger data source provides open-source, end-to-end distributed tracing.

Adding the data source

To access Jaeger settings, choose the Configuration (gear) icon, then choose Data Sources, and then choose Jaeger.

Name	Description
Name	The data source name. This is how you see the data source in panels, queries, and Explore.
Default	Default data source means that it will be pre-selected for new panels.
URL	The URL of the Jaeger instance; e.g., http://localhost:16686.
Access	Server (default) = URL must be accessible from the Grafana backend/server.
Basic Auth	Enable basic authentication to the Jaeger data source.
User	User name for basic authentication.
Password	Password for basic authentication.

Query traces

You can query and display traces from Jaeger via Explore. For more information, see Explore.

The Jaeger query editor allows you to query by trace ID directly or selecting a trace from trace selector. To query by trace ID, insert the ID into the text input.

Use the trace selector to pick particular trace from all traces logged in the time range you have selected in Explore. The trace selector has three levels of nesting: 1. The service you are interested in. 1. Particular operation is part of the selected service. 1. Specific trace in which the selected operation occurred, represented by the root operation name and trace duration.

Linking to the trace ID from logs

You can link to Jaeger trace from logs in Loki by configuring a derived field with internal link. For more information, see Derived fields.
