Tracing With OpenTelemetry Collector

Using OpenTelemetry Collector with Jaeger

The Jaeger Docker image includes OpenTelemetry Collector. So, you need not run OpenTelemetry Collector separately.

docker run --name jaeger -p 13133:13133 -p 16686:16686 -p 4317:55680 -d --restart=unless-stopped jaegertracing/opentelemetry-all-in-one

For example:

FLOGO_OTEL_TRACE=true FLOGO_OTEL_OTLP_ENDPOINT="localhost:4317" FLOGO_OTEL_TRACE_ATTRIBUTES="deployment=local,product=flogo" ./TimerOTel-darwin_amd64

Using OpenTelemetry Collector with Zipkin

Procedure
1. Start Zipkin as follows:

   docker run -it --rm -p 9411:9411 -d --name zipkin openzipkin/zipkin

2. Update the OpenTelemetry Collector configuration file for Zipkin, otel-zipkin-collector-config.yaml, as follows:

receivers:
otlp:
protocols:
http:

exporters:
zipkin:
# Change IP
endpoint: "http://xxx.xxx.x.x:xxxx/api/v2/spans"
format: proto

processors:
batch:

service:
pipelines:
traces:
receivers: [otlp]
processors: [batch]
exporters: [zipkin]

3. Start OpenTelemetry Collector with Zipkin Exporter as follows:

   docker run -d --rm -p 4318:4318 -v "${PWD}/otel-zipkin-collector-config.yaml":/otel-collector-config.yaml --name otelcol otel/opentelemetry-collector:0.35.0 --config otel-collector-config.yaml

For example:

FLOGO_OTEL_TRACE=true FLOGO_OTEL_OTLP_ENDPOINT="https://localhost:4318" FLOGO_OTEL_TRACE_ATTRIBUTES="deployment=local,product=flogo" ./TimerOTel-darwin_amd64

Using OpenTelemetry Collector with Zipkin (with TLS)

Procedure
1. Update server-cert-gen.sh as follows:

   openssl req -newkey rsa:2048 \
   -new -nodes -x509 \
   -days 3650 \
   -out cert.pem \
   -keyout key.pem \
   -extensions san \
   -config <(echo '[req]'; echo 'distinguished_name=req';
   echo '[san]'; echo 'subjectAltName=DNS:localhost,DNS:127.0.0.1') \
   -subj "/C=US/ST=California/L=Sunnyvale/O=TIBCO/OU=Flogo/CN=localhost" 

2. Start Zipkin.

   docker run -it --rm -p 9411:9411 -d --name zipkin openzipkin/zipkin

3. Update the OpenTelemetry Collector configuration file for Zipkin, otel-zipkin-collector-config.yaml, as follows:

   receivers:
   otlp:
   protocols:
   grpc:
   tls_settings:
   cert_file: /var/certs/cert.pem
   key_file: /var/certs/key.pem
   
   exporters:
   zipkin:
   endpoint: "http://xxx.xxx.x.x:xxxx/api/v2/spans"
   format: proto
   
   processors:
   batch:
   
   service:
   pipelines:
   traces:
   receivers: [otlp]
   processors: [batch]
   exporters: [zipkin]

4. Create a certs directory under the current directory and copy cert.pem and key.pem in the certs directory.
5. Start OpenTelemetry Collector with Zipkin Exporter as follows: 

   docker run -d --rm -p 4317:4317 -v "${PWD}/otel-zipkin-collector-config.yaml":/otel-collector-config.yaml -v "${PWD}/certs":/var/certs --name otelcol otel/opentelemetry-collector:0.35.0 --config otel-collector-config.yaml

For example:

FLOGO_OTEL_TRACE=true FLOGO_OTEL_OTLP_ENDPOINT="localhost:4317" 
FLOGO_OTEL_TLS_SERVER_CERT="file:///Users/dev/Installations/OpenTelemetry/zipkin/certs/cert.pem" 
FLOGO_OTEL_TRACE_ATTRIBUTES="deployment=local,product=flogo" ./TimerOTel-darwin_amd64
