Instructions on how to monitor onions w/ Nagios

Requirements

Working Nagios setup and the following packages.

tor / torsocks
- For Debian, follow Tor Project Debian Instructions summarized here:
  - echo deb http://deb.torproject.org/torproject.org jessie main > /etc/apt/sources.list.d/tor.list
  - echo deb-src http://deb.torproject.org/torproject.org jessie main >> /etc/apt/sources.list.d/tor.list
  - gpg --keyserver keys.gnupg.net --recv 886DDD89
  - gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add -
  - apt-get update
  - apt-get install tor torsocks deb.torproject.org-keyring

Nagios setup

Add the following new command to your Nagios configuration to monitor various types of onions:

define command {
    command_name        check_http_tor
    command_line        /usr/bin/torsocks /usr/lib/nagios/plugins/check_http -H '$HOSTADDRESS$' -I  '$HOSTADDRESS$' '$ARG1$'
    }
define command {
    command_name        check_ssh_tor
    command_line        /usr/bin/torsocks /usr/lib/nagios/plugins/check_ssh -H '$HOSTADDRESS$' '$ARG1$'
    }

define command {
    command_name        check_tcp_tor
    command_line        /usr/bin/torsocks /usr/lib/nagios/plugins/check_tcp -H '$HOSTADDRESS$' '$ARG1$'
    }

Apply the service check to a host:

define host {
    use                 generic-host            ; Name of host template to use
    host_name           samplea8s7df23jh7.onion
    alias               Sample Fake Onion
    address             samplea8s7df23jh7.onion
    check_command       check_http_tor!-p 8080
}


define service {
    use                 generic-service     ; name of template to use
    host_name           samplea8s7df23jh7.onion
    service_description SSH
    check_command       check_ssh_tor!-p 8492
}

define service {
    use                 generic-service     ; name of template to use
    host_name           samplea8s7df23jh7.onion
    service_description XMPP
    check_command       check_tcp_tor!-p 5222
}
