Yes, the same data can be fetched via an API Get request, for example: {blazar_endpoint}/v1/leases.

Ceilometer notification does not handle list objects; therefore, there is nothing to do and/or troubleshoot (unless, if you want to extend/add that support). That is why I am asking if you have other means to get the same data via an API GET request. If there is, you could use the Dynamic pollsters for such a task.

Hello Nitin,

Is the data you want to handle via events (in Ceilometer notification) accessible via API in Blazar?

I'm sorry, it doesn't work that way. I don't use blazar nor openstack-helm.
