Hi Vijay, thanks for your reply. If I understand correctly, the existing/planned collector in DCAE for now is only VES-collector, is it right? Do you publish those documents and demo cases material any where so that I can go through first and then discuss with you and DCAE team. Besides ‘measurementsForVfScalingFields’, is there any example for ’thresholdcrossingfields’?

Yes, DCAE can encompass different type of collectors. The ceilometers stats can be directly collector by specific mS but this was not something we have planned for R1. The VES specification does accommodate a broad type of events type. There are already some libraries distributed part of OPNV for vendors to onboard into VES. If The VNF/agent can send the stats “measurementsForVfScalingFields” then existing collector (VEScollector) can be leveraged. Specific to this topic – VES integration, we did meet with Xin Hui from VmVARE and members from Chinamobile recently and Alok from VES team have shared the documents and demo cases material. If you would like – we can arrange for separate meeting to discuss the same or cover this topic part of DCAE weekly call.

If this is doable, is there any example that I can follow? I notice that there are some fields in ves like thresholdcrossingfields that might be a good place to put ceilometer alarm datas, but I don’t find any example there.

One may exist (check with someone in the dcae project) but we chose ves for release 1 as it allows the vnfs to send things that would: not be monitorable in the VIM (app health for example),are receivable if one does not have access to the vim (ie on rackspace) or if one does not run on openstack (ie azure).

I notice that for now we are using ves client to send measurementsForVfScalingFields to DCAE collector, and DCAE will trigger a policy action to scale out a new instance. But ceilometer already do the calculation and will send out an alarm when metrics exceed some level of threshold, is it possible to let ceilometer directly send an alarm to DCAE and then trigger a policy action?
