this patch doesn't include any example output

it looks like the modification affects this api call:
http://api.openstack.org/api-ref-compute.html#limits

take the am I suppose to add

"totalVolumesUsed": 0,
"totalGigabytesUsed": 0

to the json response:
https://github.com/openstack/api-site/blob/master/api-ref/src/wadls/compute-api/src/api_samples/os-used-limits-for-admin/usedlimitsforadmin-get-resp.json

and add

    <limit name="totalVolumesUsed" value="0"/>
    <limit name="totalGigabytesUsed" value="0"/>

to the xml response:
/api_samples/os-used-limits-for-admin/usedlimitsforadmin-get-resp.xml

PS:
http://api.openstack.org/api-ref-compute.html#compute_limits_admins
this method also return response in the same format, so it points to the same example file as above, change the above file will affect both methods

can someone clarify on this?

a bit more investigation with Compute v2 api

GET {host}:8774/v2/{tenantID}/limits

{"limits": {"rate": [], "absolute": {"maxServerMeta": 128, "maxPersonality": 5, "maxImageMeta": 128, "maxPersonalitySize": 10240, "maxSecurityGroupRules": 20, "maxTotalKeypairs": 100, "totalRAMUsed": 0, "totalInstancesUsed": 0, "maxSecurityGroups": 10, "totalFloatingIpsUsed": 0, "maxTotalCores": 20, "totalSecurityGroupsUsed": 0, "maxTotalFloatingIps": 10, "maxTotalInstances": 10, "totalCoresUsed": 0, "maxTotalRAMSize": 51200}}}

Can not observe any of the following additional params

totalVolumesUsed
totalGigabytesUsed

I suspect that this fix is for API version 1? so maybe no longer valid?
