# OpenTelemetry support
|
|
|
|
kOps is experimenting with initial support for OpenTelemetry, starting with tracing.
|
|
|
|
The support should be considered experimental; the trace file format and schema will likely change, and these initial experiments might be removed entirely.
|
|
|
|
kOps supports a "serverless" mode of operation, where it logs the OpenTracing output to a file. We do this because our e2e test runner (prow) doesn't yet have a destination for OpenTelemetry data.
|
|
|
|
To try this out:
|
|
|
|
`OTEL_EXPORTER_OTLP_TRACES_FILE=/tmp/trace go run ./cmd/kops get cluster`
|
|
|
|
You should now see that the /tmp/trace file is created.
|
|
|
|
Then we have an experimental tool to serve the trace file to jaeger:
|
|
|
|
```
|
|
cd tools/otel/traceserver
|
|
go run . --src /tmp/trace --run jaeger
|
|
```
|
|
|
|
Not everything is instrumented yet, and not all the traces are fully joined up (we need to thread more contexts through more methods),
|
|
but you should be able to start to explore the operations that we run and their performance.
