After updating the firehose_exporter from 7.0.0 to 7.1.0, all calls to it seemingly return a 404. The process seems to properly start and listens on the configured port (FIREHOSE_EXPORTER_LOG_LEVEL=debug, though no additional logging seems to be shown):

# netstat -pant|grep firehose

A curl to / on the machine from which it runs (same response when calling the default /metrics endpoint):

When the 7.0.0 binary is dropped in place (same VM, same config, only binary replaced), all calls are returning proper responses again:

Hi @lodener,

thank you for the issue. I fell over it as well and created a fix already. Currently waiting for it to get approved to make it available via the prometheus-boshrelease
