Nagios Support Forum

Dear Forum!

I have installed a Nagios Core on Ubuntu 16.04 .
I would like monitoring my printers (Xerox).
I follow this site steps: https://ittutorials.net/open-source/nag ... th-nagios/ , but when I check nagios site then i get this:
http://www.kepfeltoltes.eu/view.php?fil ... 9error.jpg

after i type this lines in printer.cfg:
define service{
use generic-service
hostgroup_name printers
service_description Check Model
check_command check_snmp_printer!public!"MODEL"
}

define service{
use generic-service
hostgroup_name printers
service_description Check Toner
check_command check_snmp_printer!public!"CONSUM ALL"!5!2
}
....but again i get a problem:
http://www.kepfeltoltes.eu/view.php?fil ... error2.jpg

If I type example this lines on the ubuntu then i get perfect answer.
./check_snmp_printer -H 10.0.0.5 -C public -t MODEL

./check_snmp_printer -h 10.0.0.5 -t


./check_snmp_printer -H 10.0.0.5 -C public -t "CONSUM ALL" -w 25 -c 10

./check_snmp_printer -H 10.0.0.5 -C public -t "CONSUM ALL" -w 25 -c 10./check_snmp_printer -H 10.0.0.5 -C public -t PAGECOUNT

snmpwalk -v 2c -c public 10.0.0.5

Please help me for this problem solved and please tell me step by step how to can I install the check_snmp_printer.

Thanks!

Can you post how you defined the check_snmp_printer command so we can check the Arguments to see if they line up with the service check?

Hello!

(/usr/local/nagios/etc/objects/commands.cfg)
I wrote in the commands.cfg :
define command {
command_name check_snmp_printer
command_line /usr/local/nagios/libexec/check_snmp_printer -H $HOSTADDRESS$ -C $ARG1$ -x $ARG2$ -w $ARG3$ -c $ARG4$
}

After i allowed the printer.cfg in /usr/local/nagios/etc/nagios.cfg . (uncomment this line: cfg_file=/usr/local/nagios/etc/objects/printer.cfg)

Finally i give wrote this lines in /usr/local/nagios/etc/objects/printer.cfg :
define host {
use generic-printer ; Inherit default values from a template
host_name xerox ; The name we're giving to this printer
alias xerox ; A longer name associated with the printer
address 192.168.1.30 ; IP address of the printer
hostgroups network-printers ; Host groups this printer is associated with
}
define hostgroup {

hostgroup_name network-printers ; The name of the hostgroup
alias Network Printers ; Long name of the group
}
define service{
use generic-service
host_name xerox
service_description Check Model
check_command check_snmp_printer!public!"MODEL"
}

define service{
use generic-service
host_name xerox
service_description Check Toner
check_command check_snmp_printer!public!"CONSUM ALL"!5!2
}
define service{
use generic-service
host_name xerox
service_description check-toners
check_command check_snmp_printer!public!”CONSUM Toners”!20!10
}

The settings look good to me. I created a check on my Nagios server and it all worked as expected.
In your examples, you use 2 different IP addresses, do both of the printer support polling of that data using SNMP?
