thanks Dan and Jay,  we don't need add new scheduler for that  :-),<br>
what about provide cpu frequency to  api  /os-hypervisors, that  means<br>
we can<br>
report this value automatically,  the value can be used in high level<br>
mange tools.<br>
</blockquote>
<br>
Meh, I'm not too big of a fan of the os-hypervisors extension.<br>
Actually, one might say I despise that extension :)<br>
<br>
That said, I suppose it should be possible to include the output of<br>
the CPU frequency in the cpu_info field there...<br>
<br>
</blockquote>
<br>
Well, IMHO I don't like to have the Hypervisors API to be a Nagios-like<br>
view of the hypervisors world and I don't really much benefits of pusing<br>
the metrics up to the API.<br>
<br>
On the other hand, those monitor metrics are already sent as<br>
notifications on the bus [1] so a 3rd party tool can easily fetch them<br>
without necessarly needing to extend the API.<br>
</blockquote>
<br>
Yeah, the difference here is that CPU frequency really isn't a metric... it's a static thing that doesn't change over time. Which is why I think it's OK to put it in cpu_info.<br>
<br>
</blockquote>
<br></span>
Oh, you're right, it's a very static thing. If it's not a metric, then I would like to see it removed from the CPU monitor and provided in cpu_info then.</blockquote><div><br></div><div>Max CPU frequency may be static, but the the CPU frequency being used can be dynamic: <a href="https://en.wikipedia.org/wiki/SpeedStep">https://en.wikipedia.org/wiki/SpeedStep</a></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><span class=""><font color="#888888"><br>
