<p>OpenStack has the ability to set iops quotas with Teraform using <a href="https://registry.terraform.io/providers/terraform-provider-openstack/openstack/latest/docs/resources/blockstorage_qos_v3" rel="nofollow noreferrer"><code>openstack_blockstorage_qos_v3</code></a> which seems to correspond to <a href="https://docs.openstack.org/api-ref/block-storage/v3/" rel="nofollow noreferrer">Block Storage API 3</a> in OpenStack.</p>
<p>My question is on setting the <code>qos_specs</code></p>
<pre class="lang-yaml prettyprint-override"><code>specs = {

  write_iops_sec = &quot;40000&quot;
}
</code></pre>
<p>Can I use Horizons (the web interface) to find peak <code>iops</code> for a running  instance? If not, is this metric recorded somewhere that I can get with the API? I'd like to find his information out for a volume, and and an instance (with all the volumes backing it).</p>

OpenStack has the ability to set iops quotas with Teraform using openstack_blockstorage_qos_v3 which seems to correspond to Block Storage API 3 in OpenStack.
My question is on setting the qos_specs
specs = {
  read_iops_sec  = "40000"
  write_iops_sec = "40000"
}

Can I use Horizons (the web interface) to find peak iops for a running  instance? If not, is this metric recorded somewhere that I can get with the API? I'd like to find his information out for a volume, and and an instance (with all the volumes backing it).

It will depend on the provider of the underlying Openstack infrastructure.

You will need Monasca, Ceilometer to gather the data for you.
