How to retrieve ceilometer statistics for the meter "network.incoming.bytes" for an instance

The ceilometer meter network.incoming.bytes takes a resource id in the format <os-ext-srv-attr:instance_name>-<instanceid>-<instancephysicalportname>

I have the instance ID and can retrieve OS-EXT-SRV-ATTR:instance_name using nova API.

Is it possible to fetch the instance physical port name also using any nova API ? I see that it is available in the table instance_info_caches in mysql, but couldnt find any api that retrieves it.

Or is there a better way of retrieving the resource ID to be used here using ceilometer API itself.

Using ceilometer resource list API and checking the resource ids is a overkill in my case as this list is becoming uncontrollably large.

Any help is appreciated.

Have you tried queries? Like search for resources with metadata.instance_id=<resource_id>?

you can query direct to database with SELECT, tap.network_info FROM instance_info_caches tap WHERE tap.deleted = 0 and tap.instance_uuid="vm_id". But this way is very crazy. I want to call using api openstack

I do not read carefully. With id port id: 1109ad82-a1ac-49bb-a451-eaa736125e25 then tap name is tap1109ad82-a1

if by physical port name you have something like tap844d2678-83 , its in fact tap<11_first_char_of_interface_id>

to get the full interface_id, you can call neutron with /v2.0/ports?device_id=<instance_id>, it will return all the port (interface) of the instance, there you can get the first 11 char of interface_id and create your chain.

On my part, i'm looking for a way to make the network.incoming.bytes call take interface_id as resource_id instead of the actual <os-ext-srv-attr:instance_name>-<instanceid>-<instancephysicalportname> because I dont want to add calls just to create this crappy resource_id chain ....

Hope this help, Marmoto
