Jaeger Tracing

Ceph uses Jaeger as its tracing backend. In order to use tracing, we need to deploy those services.

For further details on tracing in Ceph, see :ref:Ceph tracing documentation <jaegertracing>.

Deployment

Jaeger tracing consists of 3 services:

#. Jaeger Agent #. Jaeger Collector #. Jaeger Query

Jaeger requires a database for the traces. We use Elasticsearch (version 6) by default.

To deploy Jaeger services when not using your own Elasticsearch (deploys all 3 services with a new Elasticsearch container):

.. prompt:: bash #

ceph orch apply jaeger

To deploy Jaeger services with an existing Elasticsearch cluster and an existing Jaeger query (deploys agents and collectors only):

.. prompt:: bash #

ceph orch apply jaeger --without-query --es_nodes=ip:port,...
