I have a bit of an odd one.
I have two printers in my observium install. One has been in for ages (an HP laser jet), the other I added a couple of weeks ago (A sharp MFD photocopier thingy).
By the looks of things, the HP has been collecting data correctly for ages, and graphing it nicely. I can see the pretty line that shows that the toner has reduced over time.
Oddly, it stopped collecting on the 7th July, and hasn’t graphed anything since then.
The Sharp, which has been in less time (since Thursday 7th), has never graphed its toner properly.
They are both showing the correct level of toner (well, the Sharp is showing two of them at -3, but I’ve checked the snmp output, and it’s returning -3, so that’s nothing to do with observium).
Even more weirdly, the toner level on the weekly graph is showing the correct number. The rest show -nan%
The Sharp:
The HP:
I don’t know much about how the graphing side of things works, so I don’t have much knowledge with which to do any debugging, but happy to send more debug info if required!
Thanks, Richard
