An opentelemetry config example with transfer traces to jaeger

README.md

Generate cassandrea schema for jaeger

(https://www.jaegertracing.io/docs/1.18/deployment/)

Generate schema:

git clone https://github.com/jaegertracing/jaeger

MODE=prod DATACENTER=dc1 sh ./jaeger/plugin/storage/cassandra/schema/create.sh | cqlsh

RUN

docker-compose up

Hmm, when tired to run

MODE=prod DATACENTER=dc1 sh ./jaeger/plugin/storage/cassandra/schema/create.sh | cqlsh

Got this error:

➜ MODE=prod DATACENTER=dc1 sh ./jaeger/plugin/storage/cassandra/schema/create.sh | cqlsh
Using template file ./jaeger/plugin/storage/cassandra/schema/v003.cql.tmpl with parameters:
    mode = prod
    datacenter = dc1
    keyspace = jaeger_v1_dc1
    replication = {'class': 'NetworkTopologyStrategy', 'dc1': '2' }
    trace_ttl = 172800
    dependencies_ttl = 0
Connection error: ('Unable to connect to any servers', {'127.0.0.1:9042': error(61, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

Well, should update doc, to change steps. first. cassandra should be launched, schema created, then whole system

Really appreciate for your time @AndrewGrachov for helping!
Oh I posted the following up question at https://stackoverflow.com/questions/63485673/how-to-correctly-use-opentelemetry-exporter-with-opentelemetry-collector-in-clie
If you have time, it would be great! Thanks again!

I have figured with some further help, I posted my final working solution at https://stackoverflow.com/a/63489195/2000548

Good - glad you worked it out :)

Thanks for helping, @AndrewGrachov !
