# Jaeger data source
|
||
|
||
Grafana ships with built-in support for Jaeger, which provides open source, end-to-end distributed tracing.
|
||
Just add it as a data source and you are ready to query your traces in [Explore]({{< relref "../explore/_index.md" >}}).
|
||
|
||
## Add data source
|
||
|
||
To access Jaeger settings, click the **Configuration** (gear) icon, then click **Data Sources** > **Jaeger**.
|
||
|
||
| Name | Description |
|
||
| ------------ | ---------------------------------------------------------------------- |
|
||
| `Name` | The data source name in panels, queries, and Explore. |
|
||
| `Default` | The pre-selected data source for a new panel. |
|
||
| `URL` | The URL of the Jaeger instance. For example, `http://localhost:16686`. |
|
||
| `Basic Auth` | Enable basic authentication for the Jaeger data source. |
|
||
| `User` | Specify a user name for basic authentication. |
|
||
| `Password` | Specify a password for basic authentication. |
|
||
|
||
### Trace to logs
|
||
|
||
> **Note:** This feature is available in Grafana 7.4+.
|
||
|
||
This is a configuration for the [trace to logs feature]({{< relref "../explore/trace-integration" >}}). Select target data source (at this moment limited to Loki data sources) and select which tags will be used in the logs query.
|
||
|
||
- **Data source -** Target data source.
|
||
- **Tags -** The tags that will be used in the Loki query. Default is `'cluster', 'hostname', 'namespace', 'pod'`.
|
||
|
||
|
||
|
||
## Query traces
|
||
|
||
You can query and display traces from Jaeger via [Explore]({{< relref "../explore/_index.md" >}}).
|
||
|
||
{{< docs-imagebox img="/img/docs/v70/jaeger-query-editor.png" class="docs-image--no-shadow" caption="Screenshot of the Jaeger query editor" >}}
|
||
|
||
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.
|
||
|
||
{{< docs-imagebox img="/img/docs/v70/jaeger-query-editor-open.png" class="docs-image--no-shadow" caption="Screenshot of the Jaeger query editor with trace selector expanded" >}}
|
||
|
||
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 Trace ID from logs
|
||
|
||
You can link to Jaeger trace from logs in Loki by configuring a derived field with internal link. See the [Derived fields]({{< relref "loki.md#derived-fields" >}}) section in the [Loki data source]({{< relref "loki.md" >}}) documentation for details.
|
||
|
||
## Configure the data source with provisioning
|
||
|
||
You can set up the data source via configuration files with Grafana’s provisioning system. Refer to [provisioning docs page]({{< relref "../administration/provisioning/#datasources" >}}) for information on various settings and how it works.
|
||
|
||
Here is an example with basic auth and trace-to-logs field.
|
||
|
||
```yaml
|
||
apiVersion: 1
|
||
|
||
datasources:
|
||
- name: Jaeger
|
||
type: jaeger
|
||
uid: jaeger-spectra
|
||
access: proxy
|
||
url: http://localhost:16686/
|
||
basicAuth: true
|
||
basicAuthUser: my_user
|
||
editable: true
|
||
isDefault: false
|
||
jsonData:
|
||
tracesToLogs:
|
||
# Field with internal link pointing to a Loki data source in Grafana.
|
||
# datasourceUid value must match the `datasourceUid` value of the Loki data source.
|
||
datasourceUid: loki
|
||
tags:
|
||
- cluster
|
||
- hostname
|
||
- namespace
|
||
- pod
|
