Tempo is a multitenant distributed tracing backend. It supports multitenancy through the use of a header: X-Scope-OrgID. This guide details how to setup multitenancy.

Multitenancy

If you’re interested in setting up multitenancy, please consult the multitenant example in the repo. This example uses the following settings to achieve multitenancy in Tempo:

• Configure the OTEL Collector to attach the X-Scope-OrgID header on push:

Copy

exporters:
  otlp:
    headers:
      x-scope-orgid: foo-bar-baz

Grafana 7.5.x and higher

• Configure the Tempo datasource in Grafana to pass the tenant with the same header.

Copy

- name: Tempo-Multitenant
  jsonData:
    httpHeaderName1: 'X-Scope-OrgID'
  secureJsonData:
    httpHeaderValue1: 'foo-bar-baz'

Grafana 7.4.x

• Configure the Tempo datasource in Grafana to pass the tenant as a bearer token. This is necessary because it is the only header that Jaeger can be configured to pass to its GRPC plugin.

Copy

- name: Tempo-Multitenant
  jsonData:
    httpHeaderName1: 'Authorization'
  secureJsonData:
    httpHeaderValue1: 'Bearer foo-bar-baz'

• Configure Jaeger Query to pass the bearer token to its backend.

Copy

--query.bearer-token-propagation=true

Important Notes

• Multitenancy on ingestion is currently only working with GPRC and this may never change. It is strongly recommended to use the OpenTelemetry Collector to support multitenancy as described above.
• The way the read path is configured is temporary and should be much more straightforward once the tempo-query dependency is removed.

Enabling Multitenancy

To enable multitenancy on Tempo backend, simply set the following config value on all Tempo components:

Copy

multitenancy_enabled: true

or from the command line:

Copy

--multitenancy.enabled=true

This option will force all Tempo components to require the X-Scope-OrgID header.
