• 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.

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

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