# OpenTelemetry Collector Traces Example
|
||||
|
||||
This example illustrates how to export traces from the otel-go sdk to the Open Telemetry Collector, and from there to a Jaeger instance.
|
||||
The complete flow is:
|
||||
|
||||
`otel-collector-demo -> otel-collector -> Jaeger`
|
||||
|
||||
# Prerequisites
|
||||
|
||||
The demo assumes you already have both OpenTelemetry Collector and Jaeger up and running. For setting these up, please follow the corresponding documentations:
|
||||
* Jaeger: https://www.jaegertracing.io/docs/1.17/getting-started/
|
||||
* OpenTelemetry Collector: https://opentelemetry.io/docs/collector/about/
|
||||
|
||||
Moreover, this demo is build against a microk8s cluster runnning both the OpenTelemetry Collector, and Jaeger. Therefor, the OpenTelemetry Collector configuration illustrated is a K8S ConfgurationMap. But the gist of it is there, so it shouldn't matter too much.
|
||||
|
||||
# Configuring the OTEL Collector
|
||||
|
||||
In order to enable our application to send traces to the OpenTelemetry Collector, we need to first open up the OTLP receiver:
|
||||
|
||||
```yml
|
||||
receivers:
|
||||
otlp: {}
|
||||
```
|
||||
|
||||
This will create the receiver on the collector side, and open up port `55680` for receiving traces.
|
||||
The rest of the configuration is quite standard, with the only mention that we need to create the Jaeger exporter:
|
||||
```yml
|
||||
exporters:
|
||||
jaeger:
|
||||
# Replace with a real endpoint.
|
||||
endpoint: "jaeger-service-url:14250"
|
||||
```
|
||||
|
||||
After this, apply the configuration to your OpenTelemetry Collector instance (with `k apply -f otel-controller-config.yaml` for k8s users). You should see that the collector creates the otlp receiver:
|
||||
```json
|
||||
{"level":"info","ts":1589184143.206609,"caller":"builder/receivers_builder.go:79","msg":"Receiver started.","component_kind":"receiver","component_type":"otlp","component_name":"otlp"}
|
||||
```
|
||||
and the Jaeger exporter:
|
||||
```json
|
||||
{"level":"info","ts":1589184143.1535392,"caller":"builder/exporters_builder.go:94","msg":"Exporter started.","component_kind":"exporter","component_type":"jaeger","component_name":"jaeger"}
|
||||
```
|
||||
|
||||
# Writing the demo
|
||||
|
||||
Having the OpenTelemetry Collector started with the OTLP port open for traces, and connected to Jaeger, let's look at the go app that will send traces to the Collector.
|
||||
|
||||
First, we need to create an exporter using the otlp package:
|
||||
```go
|
||||
exp, _ := otlp.NewExporter(otlp.WithInsecure(),
|
||||
// For debug purposes
|
||||
otlp.WithGRPCDialOption(grpc.WithBlock()))
|
||||
defer func() {
|
||||
_ = exp.Stop()
|
||||
}()
|
||||
```
|
||||
Feel free to remove the blocking operation, but it might come in handy when testing the connection. Also, make sure to close the exporter before the app exits.
|
||||
|
||||
The next steps are the same as for all other otel-go sdk uses:
|
||||
1) Create a trace provider from the `otlp` exporter:
|
||||
```go
|
||||
tp, _ := sdktrace.NewProvider(
|
||||
sdktrace.WithConfig(sdktrace.Config{DefaultSampler: sdktrace.AlwaysSample()}),
|
||||
sdktrace.WithBatcher(exp, // add following two options to ensure flush
|
||||
sdktrace.WithScheduleDelayMillis(5),
|
||||
sdktrace.WithMaxExportBatchSize(2),
|
||||
))
|
||||
```
|
||||
|
||||
2) Start sending traces:
|
||||
```go
|
||||
tracer := tp.Tracer("test-tracer")
|
||||
ctx, span := tracer.Start(context.Background(), "CollectorExporter-Example")
|
||||
defer span.End()
|
||||
```
|
||||
|
||||
The traces should now be visible from the Jaeger UI (if you have it installed).
|
||||
|
||||
# Notes
|
||||
|
||||
* There is an issue with the exporter/collector which causes Jaeger to throw errors when receiving spans from the OpenTelemetry Collector: https://github.com/open-telemetry/opentelemetry-collector/issues/815
