Hello, I have two questions about ceilometer (openstack version rocky). - First of all, it seems that ceilometer is sending metrics every hour and I don't understand why. - Next, I am not able to setup ceilometer to send metrics to prometheus pushgateway. Here is my configuration:

sources: - name: meter_file interval: 30 meters: - "*" sinks: - prometheus

sinks: - name: prometheus publishers: - prometheus://10.60.4.11:9091/metrics/job/ceilometer

Here is the error I received:
