Warning: Instance didn't return any metrics

[mpidlisnyi]

Hi,

Recently we updated datadog-agent version (Amazon Linux rpm) from 5.31.0-1 to version 5.32.2 and got a wired issue with Apache Kafka integration:

    kafka (5.32.2)
    --------------
      - instance #kafka-localhost-9990 [WARNING] collected 0 metrics
          Warning: org.datadog.jmxfetch.tasks.TaskProcessException: Instance localhost:9990 didn't return any metrics
      - Collected 0 metrics, 0 events & 0 service checks

After the investigation we found that jmxfetch-0.26.1 checks the metrics number for each check period but metrics collection runs less frequently.
kafka.yaml file had min_collection_interval: 60 sec meanwhile jmxfetch runs with option check_period: 15000
When we remove min_collection_interval from kafka.yaml file and it become to default value (15 seconds) the issue is gone.
It was working properly till we changed datadog-agent version
Could you please confirm that there is an issue with min_collection_interval for jmxfetch?

Thank you
Best Regards
