Any ideas?
A quick question - wouldn't it be more reasonable to have multiple snmp checkcommands, and only select them conditionally in service apply rules based on the host custom attribute? That would of course need some extra custom attributes as command parameters the. Though it is a more sensible approach if you decide to make use of the already existing ITL plugin check commands for snmp. http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/plugin-check-commands#plugin-check-command-snmp http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/plugin-check-commands#plugin-check-command-snmpv3 Apart from that - if you would just check in the service apply rule for the host.vars.snmp_version variable, and then set it into the service scope with "2" bevoming "2c" this would be eaven more easy. object Host "myhost" { ... vars.snmp_version = "2" } apply Service "snmp" { check_command = "snmp" if (host.vars.snmp_version == "2") { vars.snmp_version = "2c" } else { vars.snmp_version = "3" } //more snmp command attributes assign where host.vars.snmp_version != "" } Your idea with the check command isn't bad but I wouldn't go that route down there.
