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?
