After upgrading to 23.01 Status/Monitoring Thermal Sensors not updating

[00sjsl]

For my SG-4100 while on pfsence version 22.05 if I selected Status/Monitoring and then System / Thermal Sensors then I got a nice graph of temperature over time just as one would expect. After updating to 23.01 the graph won't show any readings following 09:35 on the 17th Febuary (which is the time that I upgraded to 23.01)

@00sjsl I'm guessing that this is due to the removal of the cordbuc thermal sensor from the system. You can delete /var/db/rrd/system-sensors.rrd and it will be recreated with the correct number of elements.

Alternatively, if you are brave you can use rrd tune like so:

cp /var/db/rrd/system-sensors.rrd /tmp/sensors.rrd
rrdtool tune /tmp/sensors.rrd DEL:cordbuc_0
mv /var/db/rrd/system-sensors.rrd /var/db/rrd/system-sensors.rrd.save
mv /tmp/sensors.rrd /var/db/rrd/system-sensors.rrd

If you don't care about the historical data, it's easier to simply delete the file and let it be recreated.

Thanks.
I tried the rrdtool tune approach and the graph is now updating again nicely.

I'm curious as to why corbuc_0 (which seemed to convey real information) is gone, but thermal_tz0 which is always 26.9 C remains.

Sorry, I don't know the why, just the what.
