GitHub user ub-3 closed a discussion: There is no topic in the output of metrics
I noticed that some topics don't show up in the metrics
```shell
$ curl -s localhost:8080/metrics/ | grep "my-topic-partition-2"
```
But if I check from the shell, they exist
```shell
$ sudo -u pulsar /opt/apache-pulsar/bin/pulsar-admin persistent stats
persistent://tenant/core/my-topic-partition-2
