2 day data toner level on scheduled SNMP printer sensor 0




I have several HP printers, that are in power-save during out-of-office hours. This gave me error's, so I put these printers on a Week-day Eight-to-Five schedule. This work fine.

Looking at the "Pages Printed" graphs, I only have short "uptime" of the sensor, but I get "the picture" in 2 / 30 / 365 day graphs.


The SNMP-Printer sensor give's me a ton if info. Page-Total count, Toner levels, waste-container levels, etc.

In the live-view, all is well, but in the 2 day / 30 day / 365 day, only Pages-Total count shows meaningfull info. All other counters show <zero>.

I would like historic toner level data.

Hi Thomas,

Please let me know whether you created a historic data report with "interval=No Interval (Raw Data)" in the "historic data" tab of the Sensor. In this way, you receive the list of raw data of the Sensor. If there is everything correct, the issue is only visual and should be solved via re-calculating the graph cache (Setup > System Administration > Administrative Tools > Recalculate PRTG Graph Data Cache"
