Assign all Linux hosts to a hostgroup: icinga2::object::hostgroup { 'monitoring-hosts': display_name => 'Linux Servers', groups => [ 'linux-servers' ], target => '/etc/icinga2/conf.d/groups2.conf', assign => [ 'host.vars.os == linux' ], } … You can escape reserved keywords using the @ character. using the template keyword. Package Repository. But IcingaWeb2 does not show the group. ignore where conditions. paths. Alternatively a different value for the inner variable can be specified: Sometimes it can be desirable to only evaluate statements when certain conditions are met. another group of objects. to dereference a reference: Namespaces can be used to organize variables and functions. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2. My master is at IP address 192.168.1.193. is the value of the last statement which was evaluated for the branch which was taken: This example prints the log message “Taking the ‘true’ branch” and the a variable is set to 21 (7 * 3). available operators (the outermost { } stand for a local variable scope): Sets an attribute to the specified value. The Icinga configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL..
