Troubleshooting

​

Check is Source Created?

A Source object is required for Odigos to instrument the workload or namespace, such as:

apiVersion: odigos.io/v1alpha1
kind: Source
metadata:
  name: example
  namespace: foo
spec:
  workload:
    name: myapp
    namespace: foo
    kind: StatefulSet

If you expect to see data from a workload but don’t, check if the Source object exists:

kubectl get sources -n <namespace>

​

Check is Language Detected?

After a Source object is created, Odigos will attempt to detect the programming language of the containers in the workload pods, and write the detected language to an InstrumentationConfig object in the same namespace.

The resulting language is used to determine which instrumentation to apply.

If a Source object exists, verify that the InstrumentationConfig also exists:

kubectl get instrumentationconfigs -n <namespace>

If an InstrumentationConfig object exists, verify that the status.runtimeDetailsByContainer array contains the expected languages, for example:

apiVersion: odigos.io/v1alpha1
kind: InstrumentationConfig
metadata:
  name: example
  namespace: foo
spec:
  serviceName: example
status:
  runtimeDetailsByContainer:
  - containerName: example
    language: go
    runtimeVersion: 1.21.2

​

Check is Device Instrumented?

Once an InstrumentationConfig object is created, and the supported language is detected, Odigos will wait until a destination is added, and OpenTelemetry Collectors are deployed to the cluster (which will receive the telemetry data).

To inject the instrumentation agents into the pods, Odigos will patch the workload template containers with a resource based on the detected language.

If an InstrumentationConfig object exists, and the languages are detected, verify that the Deployment object contains the expected instrumentation devices:

kubectl get deployments -n <namespace>

It should look something like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: example
  namespace: foo
spec:
  template:
    spec:
      containers:
      - resources:
          limits:
            instrumentation.odigos.io/go-ebpf-community: "1"

The instrumentation.odigos.io/go-ebpf-community resource-limit instructs Odigos on how to mount the relevant OpenTelemetry agents and environment variables into the container, and which processes should be instrumented with eBPF.
