<p><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">pyghmi is growing SDR, SEL, FRU, and other stuff.</span><span lang="EN-US"><br>
<br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I can add in-band so long as there is always python in there, however out-of-band does not need to be too bad. In the case of a baremetal guest, for example, gathering such
data in-band would require more cooperation of the tenant image, whereas out-of-band should always be workable in ipmi equipped systems.</span><span lang="EN-US"><br>
<br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">The biggest ding in out-of-band is that ipmitool is one-to-one and also has to retrieve SDR every time it wants to go read sensors. pyghmi will support an evolution of xCAT's
SDR caching scheme to avoid the hit (at least if the sensors objects are reused). We have had success completing a complete sensor read of 4,000 systems with a single system in about 15 seconds out of band in xCAT, and pyghmi optimizes away some overhead
that xCAT did not (though that overhead isn't as significant for something as verbose as sensor reading).</span><span lang="EN-US"><br>

<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:36.0pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif"">1. What kind of IPMI data will be collected? I assume that power, temperature or other sensor data is needed, right?</span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif""> </span><span lang="EN-US"><br>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif""> </span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif"">IIUC, ironic did not involve too much about IPMI for now, only used ipmitool and pyghmi module.
</span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif"">Using IPMItool to execute command and parsing the output is easy to understand. But seems not a good way for me. The pyghmi only supports out-of-band(net-payload) now. So,
I am wondering if we can extend the function of pyghmi to provide more interfaces?</span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif"">Be specifically, I think pyghmi can provide in-band IPMI interface including IPMB or system interface etc. and allowed to get IPMI data in the OS.</span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif""> </span><span lang="EN-US"><br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Calibri","sans-serif"">Is all this make sense to you?</span><span lang="EN-US"><br>
