without a trace

Generating Kubernetes service maps, no trace required.

📓 Lightstep Notebook Example

requirements

• k8s cluster connected to kubectl
• running services in the cluster (active network traffic needed)

components

• collector - OpenTelemetry collector with a custom metrics receiver to inspect pod-level network traffic.
• synthetic_traceassembler - Python script that generates synthetic traces by querying the public Lightstep API for metrics sent by the collector (query_timeseries endpoint).

deploy collector to cluster

Deploy a collector to a Kubernetes cluster to get metrics to build traces.

See collector/readme.md for instructions.

run traceassembler locally

After the cluster is running, assemble synthetic traces from the metrics being sent into the account.

1. Install python dependencies: pip3 install -r requirements.txt

2. Make some synthetics traces from metrics:

    # these are different values!
    $ export LS_PROJ=your-ls-project-name
    $ export LS_ORG=your-ls-org-name
    $ export LS_API_TOKEN=your-api-token
    $ export LS_ACCESS_TOKEN=your_access_token
    $ python3 traceassembler.txt

3. Enjoy dependency maps without any trace instrumentation 🎉
