Nagios Support Forum

I need your help please with this issue:
When i am trying to use this snmp service i am receiving the following error: UNKNOWN: check_snmp_printer: No usable 'bc' binary in '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

Here you can find the config for host and command:
HOST

• define host{
  use linux-server ; Name of host template to use
  ; This host definition will inherit all variables that are defined
  ; in (or inherited by) the linux-server host template definition.
  host_name bizhubc284e
  notes_url http://private ip
  alias bizhubc284e
  address private ip

  check_command check-host-alive
  contacts nagiosadmin
  notification_interval 60

  }
  define service {
  host_name bizhubc284e
  use generic-service
  service_description CONSUM_ALL
  check_command check_snmp_printer!public!"CONSUM ALL"!20!10
  normal_check_interval 10
  retry_check_interval 1
  }

COMMANDS

• define command {
  command_name check_snmp_printer
  command_line $USER1$/check_snmp_printer -H $HOSTADDRESS$ -C $ARG1$ -x $ARG2$ -w $ARG3$ -c $ARG4$
  }

Could you please advise?

Are you using Nagios Core or Nagios XI? I'd like to move this to the appropriate forum.

And while I'm asking, could you give us version numbers and the OS on which Nagios is running too? Thanks!

I am using Nagios Core 4.2.1 with plugins 2.1 and is installed on ubuntu server 16.04.

Your system is missing the BC package and it needs to be installed by running the following on your server. Try that and let us know if this works.

Let's try apt-get -y install bc

If that doesn't do it, then we'll have to add it to your path manually.

Thank you for you kind support guys!! Now is ok. Really thank you!!!

Whoops, didn't see @tgriep's response. But hey, at least we were on the same page!

This seems resolved. Ready to close?
