<div class="WordSection1">
<p class="MsoNormal">Hi, I’d like to log IPMI SEL events for changes in the signals monitored by OpenBMC/host-error-monitor. I don’t have much experience with OpenBMC’s sensors yet so I’m not sure what the best approach is and am looking for some guidance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I haven’t found a good example yet of a IPMI discrete sensor and I don’t want to put IPMI specific information into host-error-monitor to directly add SEL events via phosphor-sel-logger.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here’s my understanding thus far :<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">* A module needs to instantiate dbus sensors representing the signals being monitored. This could be done in host-error-monitor or duplicate some of the functionality in dbus-sensors. Is there a benefit to extending one over the other?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">* One or more IPMI SDRs should be created for the IPMI sensors needed to group all the necessary discrete offsets. If I’m using entity-manager in my build, is that where I would define this sensor? If not, is there some other way to accomplish
this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">* phosphor-sel-logger then needs to monitor (match) dbus discrete sensor property changes to create appropriate IPMI and redfish logs for the events as they occur.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does that sound about right? Thanks in advance for your help.<o:p></o:p></p>
