sdk api and follow question / bug
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I'm using API to get stats about the VM using the FOLLOW syntax described in http://ovirt.github.io/ovirt-engine-api-model/4.2/#documents/003_common_ concepts/follow In my case I list all VM with FOLLOWING - 'statistics', - 'nics.statistics', - 'disk_attachments.disk.statistics' On my env with about 50 VM the query took about 12s but the paring for the monitoring system is easy.

Hi,
I'm using API to get stats about the VM using the FOLLOW syntax described in http://ovirt.github.io/ovirt-engine-api-model/4.2/#documents/003_common_ concepts/follow
In my case I list all VM with FOLLOWING - 'statistics', - 'nics.statistics', - 'disk_attachments.disk.statistics'
On my env with about 50 VM the query took about 12s but the paring for the monitoring system is easy.
The question is, it's better to split the code and use more queries as the note in the API docs recommends? Not sure it will be faster and less cpu intensive on the engine side.
It won't. It's better just in terms of network load, not engine load.
Also the disk_attachments.disk.statistics on VMs seems to be broken, I'm not getting the data on 4.2.2 installation. /using json syntax, not xml/
Can you please describe what exactly isn't working? You won't get that for any VM? Can describe the steps how to reproduce it? Do you get HTTP 404 or 500?
regards Peter
