Service running without errors but unable to access /metrics endpoint

[hestiacloud]

Hi,

Thanks for a great exporter! I am running multiple instances of the exporter (4) for different oracledb instaces and it all worked well for a couple of days but now I am suddenly getting either "Connection refused" or it just hangs on localhost:port/metrics on couple of instances. These are all using the same configuration, the only difference is port. Changing port does not help, one or two instances always fail to expose metrics on the /metrics endpoint. Debug log is showing all metrics getting pulled correctly, no errors whatsoever.

Does anyone know what the issue might be?

Did you try to monitor the session count?

You may need to restart the exporter.
