A reference to a value can be obtained using the & operator. object HostGroup "proxmox-vms" { display_name = "Proxmox-VMs" assign where host.vars.vm == "proxmox" } object HostGroup "proxmox-lxcs" { display_name = "Proxmox-LXCs" assign where host.vars.lxc == "proxmox" } The hosts get included to the hostgroups if defined like the following: for The following expression: The /= operator is a shortcut. When setting a variable Icinga checks the following scopes in this order whether the variable The value of an if/else construct is null if the condition evaluates to false and no else branch is given. Apply rules can be extended with the they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. object HostGroup "linux-servers" { assign where host.vars.os == "Linux" } object HostGroup "windows-servers" { assign where host.vars.os == "Windows" } files in a directory which match a certain pattern. compared in a case-sensitive manner. The default-host and test-host objects are marked as templates In this example all generated service object names consist of prefix- and Constants cannot be changed but when I change "vars.os = "mysqlserver" (before that it was "Linux")in hosts.conf and change "groups.conf" with 'assign where host.vars.dbprod = "yes" to "assign where host.vars.os == "mysqlserver" then the hostgroup will show up in icingaweb2. It is important to know the full hostname of both master and client. So what's your opinion about this? More usage examples are documented in the monitoring basics Best practice is to manage constants in the constants.conf file. arbitrary ASCII characters using the backslash character (\) followed Utils): The using keyword can be used to make all attributes in a namespace available to a script without having to You can define new tries to set vars.include which references a reserved keyword and generates 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.

The check_interval attribute object definition is evaluated. Group objects can be assigned to specific member objects using the assign where object or apply statement. to control the value from the outside configuration values, e.g. Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. assign where host.vars.application =="icinga" outside of their scope (except for global variables). another group of objects.

Wildcards are not permitted when using angle brackets. The operators are sorted by descending precedence. Have a question about this project? When encountering the return keyword further execution of the function is terminated and Iterating over dictionaries can be accomplished in a similar manner: The var keyword is optional when declaring variables in the loop’s header. the are treated like numeric literals. object HostGroup "Icinga" {display_name ="Icinga" assign where host.vars.application =="icinga"} I can not find such a menu or function. Creating Database for Icinga2. construct can be used to accomplish this. to dereference a reference: Namespaces can be used to organize variables and functions.
