Dell idrac not properly discovered?

I’ve got a Dell r710 with idrac module installed. The module is discovered in librenms, but I have no graphs of anything. I have attempted a rediscovery a couple of times. This is quite possibly newbie error. Are there any suggestions as to what I should try?
I’ve got a number of other devices that are properly discovered.

The following are my librenms details:

I have to admit that the first run of validate.php did return a number of error messages. I therefore ran through the installation and made some changes here and there (most relevant of which was probably /etc/snmp/snmp.conf).
I now do have two graphs called as follow: “This attribute defines the overall chassis status” and “This attribute defines type of a remote access card”.
I had hoped for graphs on temperature, fan speed, power and such like, but maybe that isn’t available? I’ve run a “Capture Debug Information” on the discovery of it, maybe it is of some relevance?

I’ve now configured librenms to poll the idrac using IPMI and I’m now getting the data I was after. Still somewhat surprised the data doesn’t seem to be exposed via SNMP.

Have you checked whether it is exposed over snmp for you?
