I have added a script to the wikithat uses mbmon to graph motherboard temperatures.

Let me know how it goes...

This doesn't seem to work. It shows the temps find as it adds them in to the DB. But there is nothing inside the image files.

Also is there anyway the two temps could be put in to one image file to save space?

Might be worth deleting the db files so they are recreated from scratch. (/var/lib/rrd/cputemp.rrd & mbtemp.rrd)

It sounds like a good idea but I'd personally like to keep the graphs all on a separate page as opposed to clogging up the index.html. You're free to tinker with the stuff as much as you want though and I'd love to see any new additions or revisions.

Now that rrdtools is in R5E50, I'd appreciate it if someone kept me updated on any changes.
