-----------------------------------
Summary: Flink otel reporter doesnt report any metrics
Key: FLINK-39347
URL: https://issues.apache.org/jira/browse/FLINK-39347
Project: Flink
Issue Type: Bug
Components: Runtime / Metrics
Affects Versions: 2.2.0
Reporter: Sujit Joshi
Hi,
Im running Flink 2.2.0 in a Docker Compose setup. We'd like to include only
certain metrics exported to our otel collector. For this we are using
`metrics.reporter.otel.filter.includes` in our yaml file. But no matter what
format I use to export, the included metrics are never exported.
We have tried with following formats:
```
metrics.reporter.otel.filter.includes: flink.jobmanager.taskSlots.total
```
```
metrics.reporter.otel.filter.includes: >
flink.jobmanager.taskSlots.total
```
```
metrics.reporter.otel.filter.includes:
- 'flink.jobmanager.taskSlots.total'
```
```
metrics.reporter.otel.filter.includes: >
*.jobmanager.*
```
After enabling debug mode, I always see this log:
`2026-03-27T20:25:19.608364491Z 2026-03-27 20:25:19,608 DEBUG
