Yesterday evening at 5:30pm I replaced a switch. All was working fine afterwards - for a while. At 6:50pm four of our printers stopped reading the Total Pages Printed snmp setting. Just four of them - there are about a dozen other printers that are still reading that setting just fine. The ping sensor is working properly, I can get into the GUI of the printers, and doing a sensor discovery detects plenty of other snmp sensors I can add. But pages printed is not one of them.
Obviously this has something to do with swapping the switch out, but I have no clue what in the world it could be.
Any suggestions on where to start?
I further tested things out by walking the OIDs. While I could get a huge list of other OIDs the ones in the area of Total Pages Printed would not enumerate.
In the end I hard power cycled the printers and the sensors started working again. One of the oddest things I've run into.
