Hi All,
For anyone who comes across this thread, here's what I've tried.
Worked with SNMP to no avail. If I had an MIB, I'd reapproach this.
Attempted to set up SMTP. The relay host only accepts IPs and not FQDNs. We configured an internal server, but were unable to relay messages off of it successfully. Next steps here would be to find a log to review or a packet capture. For now, I've set this aside.
Installed IPMItool on a Debian host and ran this command:
ipmitool -I lanplus -H x.x.x.x -U user -P password sensor list
(Substitute your IPMI IP for x.x.x.x and your IPMI user/password.)
Success... a list of all BMC-supported sensors:
After successfully implementing item 3, we pointed Zabix at the IPMI IP and can now view all the sensors. I'm still testing triggers in Zabix, but it seems to have found a path forward.
I'd love to hear what others are doing.
