I am trying to monitor my HP printers toner (percentage) levels (other than just an up/down status). I tried to import the HP MIB with no luck. Is there a way to do this via SNMP?
There was another entry in the knowledge base that asked basically the same question with no response.

Hi Ken
this is something I have wondered about too. I should warn you that I am not an expert on PRTG or SNMP; you will guess this when you read my response.
I had a quick scan on the Internet for any help on what the oid values might be and I couldn't find anything. So I used SNMPwalk to get a list of all the oids on my HP CM3530 printer. I then looked at the values returned and matched these against the values I could see for % remaining on the printers supplies status page. These then are the oid values for % remaining for
black:1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.1.37.1.0 cyan:1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.1.37.2.0 magenta:1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.1.37.3.0 yellow:1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.1.37.4.0
So, you can create SNMP Custom sensors in PRTG using these oid values and get the % remaining for each of the cartridges.
A big warning goes with this that they may be different on your printer, and maybe someone with better knowledge of PRTG and SNMP will say my method is flawed.
There are also values in there for pages printed and pages remaining for each cartridge. The pages remaining figure is problematical for monitoring as it is only calculated after 25% of the toner has been used. Until then it is blank. This blank value puts the Sensor in to an alarm state if you use a SNMP Custom sensor. You can use a SNMP Custom String sensor but the value is then in the message and the value graphed by PRTG is the response time.
I hope this may be of some help. Joseff
