Re: [ceilometer] ceilometer metrics for list fields in event payloads

9 Jan 2026

      It's not about blazar or Openstack-Helm.

You can see it as, when Ceilometer gets an event notification, a payload is
received with a data set in json format as mentioned in the trailing mail.
My goal is to fetch a value from a list of "key:value" pairs for each
dictionary item in this list. This list is nested as a "value" of a "key"
in payload:

Payload: {
     key1: value1
     key2: value2
     key3: [
                 {
                    keyA: valueAa
*                    keyB: valuesBa  <<<<<==== I want to fetch this
valueBa  for creating a metric for keyB*
                    keyC: valueCa
                  },
                 {
                    keyA: valueAb
*                    keyB: valuesBb  <<<<<==== I want to fetch this
valueBb  for creating a metric for keyB*
                    keyC: valueCb
                  },
                 {
                    keyA: valueAc
*                    keyB: valuesBc  <<<<<==== I want to fetch this
valueBb  for creating a metric for keyB*
                    keyC: valueCc
                  }
      ]
}

*Is Ceilometer/Gnocchi able to fetch this type of data for creating metrics
and use for the "volume" field in the metric?*

Thanks & Best Regards,

*Could you please provide a solution for this!
I'm sorry, it doesn't work that way. I don't use blazar nor openstack-helm.
