Jaeger Tracing
==============
Ceph uses Jaeger as the tracing backend. in order to use tracing, we need to deploy those services.
Further details on tracing in ceph:
`Ceph Tracing documentation <https://docs.ceph.com/en/latest/jaegertracing/#jaeger-distributed-tracing/>`_
Deployment
==========
Jaeger services consist 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 tracing service, when not using your own ElasticSearch:
#. Deploy jaeger services, with a new elasticsearch container:
.. prompt:: bash #
ceph orch apply jaeger
#. Deploy jaeger services, with existing elasticsearch cluster and existing jaeger query (deploy agents and collectors):
.. prompt:: bash #
ceph orch apply jaeger --without-query --es_nodes=ip:port,..
