[Telemetry] Error when sending to prometheus pushgateway

3 Jul 2020

      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:
...
