thanks.

I'm missing where this will be in the engine dialog (in new/edit
vm), and that engine should probably get the log event on the
watchdog event, not only vdsm.

<font size="3"><font color="#000000">Watchdog</font></font> event is
very important for high reliability. It can tell what's wrong on the
guest.<br>
<br>
I'm considering a new patch after this patch was merged. It can
support a new API or channel to notify the <font size="3"><font color="#000000">watchdog</font></font> event to the engine. <br>
<br>
Seems there is not an asynchronous event channel for engine. <br>
<br>
Maybe a new API for the engine. Engine can poll it to check the <font size="3"><font color="#000000">watchdog</font></font> event.<br>
<br>
I will discuss it on the ovirt IRC channel with the engine expert.
<br>

Currently, we do not have any plans to implement the engine side
of the feature. <br>
But I will add a watchdog feature page to describe how engine
enable this feature. It's definitely great if any engine guy
would like to take the engine part. I will be glad to provide
help if needed.</font></font></blockquote>Hi Sheldon,<br>Any news on the engine side?<br>Currently the vdsm side is merged, while the engine side still missing.<br>The wiki page also lacks the engine side.
