  • Well, can you show the services that **are running** in the `osm` namespace? Error says `kafka` isn't one of them. And do you really need both `KAFKA_EXPORTER_KAFKA_CONNECT` and `--kafka.server`? – OneCricketeer Jan 28 '23 at 02:05
  • Thanks for your reply.. actually there is no namespace called "osm" everything running on default namespace only .. and which one do u suggest "- --kafka.server=kafka.osm.svc.cluster.local:9092 - --web.listen-address=:9092" or - name: KAFKA_EXPORTER_KAFKA_CONNECT value: kafka-broker-644794f4ff-8gmxb:9092 for mentioning kafka server details so that i will go ahead and do the changes – Vijay Khanna Feb 01 '23 at 02:02
  • If there's no osm namespace, why are you using it as part of the DNS name? Where are those environment variables documented? I think you should remove both of them. Your web listen address also needs to be 9308, since that's your actual containerPort. And why not use Helm? https://github.com/danielqsj/kafka_exporter/tree/master/charts/kafka-exporter#helm-install – OneCricketeer Feb 01 '23 at 04:30

actually there is no namespace called "osm" everything running on default namespace

Refer kubernetes documentation.

As the error says, there's no service kafka in an osm namespace (whether that exists, or not), that can be reached. Remove .osm from that address, or change it to .default, assuming that there really is a Service named kafka available at port 9092
