Monitoring hexadecimal SNMP values

[pmgeahan]

Folks -

I'm using Zabbix Server 1.4.1 on Ubuntu. I'm using it, in part, to monitor some SNMP v1 switches and printers.

The HP printers on my network recognize the hrprinterdetectederrorstate object - in this case, giving information on the state of paper and toner in the system. THe object is described in the docs as such:

This object represents any error conditions detected by the printer.  The error conditions are encoded as bits in an octet string, with the
 following definitions:

                    Condition         Bit #    hrDeviceStatus

                    lowPaper          0        warning(3)

                    noPaper           1        down(5)

                    lowToner          2        warning(3)

                    noToner           3        down(5)

                    doorOpen          4        down(5)

                    jammed            5        down(5)

                    offline           6        down(5)

                    serviceRequested  7        warning(3)

Problem is, I can't figure out how to set up a trigger based on this information; I don't quite know how to set up the trigger and/or the item to recognize the hexadecimal values. If I cast the item as a character, the return is a superscript three; if I cast it as a number, Zabbix won't even give me the data.

Does anyone have an idea as to how I could process this value?

Thanks!
