Tracing Services

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 Ceph tracing documentation.

Deployment

Jaeger tracing consists of 3 services

1. Jaeger Agent

2. Jaeger Collector

3. 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)

ceph orch apply jaeger

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

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