No IPMI Sensors are shown in the GUI


I’m trying to poll IPMI-Sensors, as most Linux’ or Windows Hypervisors are only providing SNMP Sensor readings via lots of additional configs. All of our BMCs supply the necessary Sensors via different CLI Tools.

However, the Sensors are not shown on any device, except the Dell iDrac Devices (but those are not the ones i wan’t to poll).

The Sensors are also polled and read correctly via the ./poller.php and ./discovery.php stuff.
The Data is also correctly read. However, the Data is not shown in the GUI.

This is also the case for 7 other Servers that have a very similar Setup (AST2500/AST2600 BMC, very similar to what Supermicro uses in newer models)

Is there something i can configure, without having to set all sensors manually for each device?

If you are having troubles with discovery/polling include the pastebin output of:

./discovery.php -h HOSTNAME -d | ./

./poller.php -h HOSTNAME -r -f -d | ./

Edit: I just noticed, that if i add the device via the GUI, put the IPMI Login-Data in and let it be - the IPMI Sensors never get populated. (Been over a Week)
However, if i then do a ./discovery.php the Sensors get added - but no Data. If i do another ./poller.php, the Data get’s populated.

Is this intentional or is this some kind of Bug?
