1. Check that the Apache Kafka Event Source consumed the message and sent it to
its sink properly.
its sink properly. Since these logs are captured in debug level, edit the key `level` of `config-logging` configmap in `knative-sources` namespace to look like this:
```
data:
loglevel.controller: info
loglevel.webhook: info
zap-logger-config: |
{
"level": "debug",
"development": false,
"outputPaths": ["stdout"],
"errorOutputPaths": ["stderr"],
"encoding": "json",
"encoderConfig": {
"timeKey": "ts",
"levelKey": "level",
"nameKey": "logger",
"callerKey": "caller",
"messageKey": "msg",
"stacktraceKey": "stacktrace",
"lineEnding": "",
"levelEncoder": "",
"timeEncoder": "iso8601",
"durationEncoder": "",
"callerEncoder": ""
}
}
```
Now manually delete the kafkasource deployment and allow the `kafka-controller-manager` deployment running in `native-sources` namespace to redploy it. Debug level logs should be visible now.
```
$ kubectl logs --selector='knative-eventing-source-name=kafka-source'
