They are, however, aware of the same information. The Brothers just don't use the "remaining space" version. That could potentially work, but would offer nothing to graph, etc. My understanding is that there is a low threshold, beyond which the printer returns a -2. That the printer knows that there is some supply/remaining space,Ĭlearly, the -3 is not unexpected.

On the Dells, that OID returns a number that represents the number of units left, whether that's pages, grams, impressions, whatever, but an actual number that counts down as the printer is used. There is a standard printer OID for supply levels that is working great on most of my printers. I've got Opsview working with all my Dell printers. I can hit the web interface of course, but I'm looking for something more automated. At the moment, the "alert" comes when someone can't print because the toner is out. The most immediate use for the system will be monitoring (or more to the point, alerting me about) printer toner levels. I'm setting up an Opsview (nagios) server for monitoring.
