Hallo,
our office uses an HP Officejet Pro 8600 N911a and I'd like to query the ink levels with SNMP.
I can see all of the values when I'm using snmpwalk, but drilling down with snmpget I receive an error message at querying .4
# snmpwalk -v1 -c xxx 192.168.nnn.yyy 1.3.6.1.2.1.43.11.1.1.9.0
SNMPv2-SMI::mib-2.43.11.1.1.9.0.1 = INTEGER: 231
SNMPv2-SMI::mib-2.43.11.1.1.9.0.2 = INTEGER: 94
SNMPv2-SMI::mib-2.43.11.1.1.9.0.3 = INTEGER: 210
SNMPv2-SMI::mib-2.43.11.1.1.9.0.4 = INTEGER: 174
# snmpget -v1 -c xxx 192.168.nnn.yyy 1.3.6.1.2.1.43.11.1.1.9.0.4
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::mib-2.43.11.1.1.9.0.4
I have browsed the german and english forums for other posts about SNMP, but found ambiguous information. Some posts say that .4 would be magenta. Anyway: the ink levels do not resemble the numbers I get with snmpwalk.
How do I have to interpret or recalculate the numbers?
For the above numbers the ink levels were approx. (from the display)
M 75%
C 90%
Y 30%
K 25%
Are the values a percentage of 255? Is there some other more complex formula?
Please don't suggest using the webinterface. I tried it and it is awkward. The current 8600 web interface is a mess of JS code unlike the earlier G95 and L7780 which I could handle quite fine with wget queries. I want to automate the ink monitoring with Nagios, and I really need snmpget working.
Thanks,
Tschau...Thomas
