Monitoring toner levels in network printers
In this tutorial, we will set up a SNMP monitor to watch the amount of toner remaining in a printer.

Setting up monitoring parameters
We assume you have followed all the steps to create SNMP monitor already. Now select monitor’s Main parameters tab to continue.
Launch the MIB browser (see above how to do that) to proceed. If you haven’t loaded proper MIB files (you would need IANA-PRINTER-MIB and Printer-MIB v2), MIB browser will not show you much useful information (most OID tree entries will be marked Unknown). Download the mentioned MIB files, click on “MIBs” button (lower left corner of the MIB browser) and look whether the required MIBs are loaded already.
|If IANA-PRINTER-MIB and Printer-MIB are both present in the list, just skip this step. Otherwise, make sure the downloaded MIB files are placed into %ProgramData%\IPHost Network Monitor\mibs and click “Import” button. Select one of MIB files and click “Open”. Import the other MIB file in the same way, if required.|
|Now refresh MIB browser main view by clicking “Refresh” button. To find OIDs related to measuring toner amount, enter word “Supplies” to the right of “Find” label. The browser will only display those entries with the mentioned word present in their names.
We will use “prtMarkerSuppliesLevel(9)” entry. Note: the whole OIDs tree and values of the entries may be different in your case.
Select the mentioned entry and click “OK” to return to monitor Main parameters tab.
|Now let’s set up monitor so that it triggered an alarm wherever the supplies level (toner amount) is depleting too low.
Open State conditions tab in Parameters/Results pane.
Warning state condition is used when the monitored parameter isn’t already acceptable, but the value isn’t that wrong to raise an alarm. Down state condition is used when it is time to raise a real alarm.
Please consult your network printer reference for accurate values. In our example, we will trigger a warning when there are less than 20 units of toner supplies left, and make the monitor change to Down state when there’s less than 5. You should choose whatever values are relevant in your case.
