<div dir="ltr"><div>How frequent do you imagine these notifications being? There's a wide variation here between the 'blue moon' case where disk space is low and frequent notifications of things like OS performance, which you might want to display in Horizon or another monitoring tool on an every-few-seconds basis, or instance state change, which is usually driven by polling at present.<br>
<br>I'm not saying that we should necessarily design notifications for the latter cases, because it introduces potentially quite a lot of user-demanded load on the Openstack components, I'm just asking for a statement of intent.<br>
