<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">I agree that the VM Heartbeat / Health-check looks like a good fit into Masakari.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Currently your instance monitoring looks like it is strictly black-box type monitoring thru libvirt events.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Is that correct ?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">i.e. you do not do any intrusive type monitoring of the instance thru the QUEMU Guest Agent facility<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"> correct ?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">I think this is what VM Heartbeat / Health-check would add to Masaraki.<o:p></o:p></span></p>
