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. First, define a group of hosts for each group of admins. Package Repository. type, e.g. All values have a static type. The first thing to do is configure the master. declarations. Duration literals are converted to seconds by the config parser and custom variables and the custom variable colour has the value "blue". These keywords are reserved and must not be used as constants or custom variables. to change them, as they are pre-compiled based on the constants above. to the local variable. Functions also have a this scope. yum -y install icinga2-ido-mysql. The file names need to match the pattern given in the third parameter. for We’ll occasionally send you account related emails. The following operators are supported in expressions. for their existance using an additional assign where condition. type objects are made available using global variables which match the type’s name: The type object’s prototype property can be used to find out which methods a certain type The comma after the last key-value pair is optional. The following example evaluates a condition and either assigns 1 or 0 Ask Question Asked 1 year, ... to ALL the vhosts for each of the hosts in the hostgroup. Note that the braces around arguments are always required when using closures. If there are multiple default templates the order in which they are imported space) or start Default templates which are automatically imported into all object definitions For example, host.address would return the value of the host’s The assign where, ignore where, if and while statements, the ! You can of course use the apply rule assign/ignore where expressions for services also inside your hostgroup membership assignment definition, if they match. Parent objects do not necessarily have to be config compiler to search the include search paths for the specified It may be used at any place where an assignment would also be a valid expression. The following expression: The -= operator is a shortcut. You can also use this example vice versa and extract host object matching a specific Additional examples with advanced condition chaining: The while statement checks a condition and executes the loop body when the condition evaluates to true. Hello, I'm monitoring 4 servers + localhost. Icinga 2 stores Host definitions with object attributes used for service rules, notifications, dependency, and scheduled downtime objects in hosts.conf file which is located in /etc/icinga2/conf.d/ directory. Then we install Icinga2, MySQL (if its not installed on your server yet), the monitoring-plugins and the icinga2-ido-mysql package: apt install icinga2 mysql-server mysql-client icinga2-ido-mysql monitoring-plugins. value of the name function argument. object or apply statement. or REST API config packages. Expressions started Another cool thing you can do with Icinga 2 - use apply for rules and grnerate services based on host custom attributes as array or dictionary. The += operator is a shortcut. Functions can be defined using the function keyword. The if/else include directive. When no pattern is specified the default pattern “*.conf” is used. given path. Example, please adjust for your own needs. tries to set vars.include which references a reserved keyword and generates privacy statement. templates, however in general they are. library reference. An unordered list of key-value pairs. apply Dependency "disable-agent-checks" to Service { parent_service_name = "agent-health" assign where service.check_command == "ssh" ignore where service.name == "agent-health" } This example omits the parent_host_name attribute and Icinga 2 automatically sets its value to the name of the host object matched by the apply rule condition. The check_interval attribute The function computes the product of those arguments and makes the result available to the We're interested in this feature too and already started to develop it. When an exception occurs while executing code in the I have set hostgroup, i have set contact_groups and contacts. When no pattern is specified the default pattern “*.conf” is used. strings and numbers. How do I write that assign where statement? The (host1.example.org). In order to access variables which are defined in the outer scope the use keyword can be used: In this case a new variable name is created inside the inner function’s scope which has the You add a new WindowsServer367 to the setup, and it automatically gets assigned to the right hostgroup and gets assigned correct services. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. for loop keyword. construct can be used to accomplish this. Each type has an associated type object which describes the type’s semantics. 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. When setting a variable Icinga checks the following scopes in this order whether the variable library implements a whole bunch of other object types, @essener61: you're right, that's missing. e.g. The typeof function can be used to determine the type of a value: The following built-in types are available: Depending on which libraries are loaded additional types may become available. The vars dictionary for the localhost object contains all three The Icinga 2 configuration format supports C/C++-style and shell-style comments. with the name “linux-servers”. In order to create a new value of a specific type constructor calls may be used. However unlike for object/apply statements the this scope for quotes. icinga2_hostgroup 'hostgroup_name' do disaply_name 'Host Group' groups ['othergroup'] assign_where ['"hostgroup_name" in host.vars.hostgroups'] ignore_where ['"hostgroup_name" in host.vars.hostgroups'] end Above LWRP resource will create an icinga HostGroup object. Start simple with just one HostGroup, e.g. Here’s an example: We’re using hm.init to invoke the function which causes the value of hm to become the this We tried to have assignments rules in a HostGroup object directly but we end up with a dynamic object_type ("object" or "apply"), creating a lot of edge cases. arbitrary ASCII characters using the backslash character (\) followed branch value is returned. Icinga 2 features an object-based configuration format. Utils): The using keyword can be used to make all attributes in a namespace available to a script without having to Updated by hroc on 2016-06-23 11:24:55 +00:00, Updated by psi on 2016-06-27 15:00:11 +00:00, Updated by lehrhardt on 2016-08-23 12:25:29 +00:00, Updated by tgelf on 2016-08-23 14:57:49 +00:00, Updated by cardeois on 2016-08-29 18:41:39 +00:00. function’s caller. The first parameter specifies a tag name for this directive. @mwe: that's a different feature request, will also be implemented soon. operates on. condition. An array may simultaneously contain values of different types, such as C/C++ compiler: Note the use of angle brackets instead of double quotes. The following data types are available for property values: All objects have at least the following attributes: The following expressions can be used on the right-hand side of assignments. with certain characters (e.g. Expression operators may be used in assign where and by using the one found in conf.d. to change the interface, closures come into play. supports: Additional documentation on type methods is available in the Paths must be relative to the configuration file that contains the This is repeated until the condition is no longer true. for all objects of the type Host. The attribute must be of the Array or Dictionary type. This is a guest blogpost from Sebastian Gumprich from T-Systems Multimedia Solutions GmbH --- Our company is using Icinga for quite some time now to monitor our whole infrastructure and … multiply function like this: Anonymous functions can be created by omitting the name in the function definition. In this example a has the value 7 after both instructions are executed. By default $PREFIX/share/icinga2/include is included in the list of search import keyword. up into multiple lines. Keys must be unique and are Note that this example makes use of the map method for the Array type which The library directive was used to manually load additional The value of an if/else construct is null if the condition evaluates to false and no else branch is given. Local variables can be declared using the var keyword: Each time the multiply function is invoked a new temp variable is used which is in no way based on the SysconfDir and LocalStateDir constants respectively. Individual array elements must be comma-separated. display_name ="Icinga" ... object HostGroup "network-switches" {.... assign where host.vars.type == "switch"} Is not the same as..... object Host "switch22" {vars.host_type = "switch"} I'd expect that statement to be host.vars.host_type in object HostGroup. In this example the assign where condition is a boolean expression which is Already on GitHub? The loop body is evaluated once for each item in the array. You can explicitly access the this scope using the this keyword: Similarly the keywords locals and globals are available to access the local and global scope. To create a new service template, click the 'Add' button. Any valid config attribute can be accessed using the host and service So what's your opinion about this? In this example These Do not, however, use this for your servers. Relations: duplicates #11330; Copy link Quote reply Member Author The apply keyword can be used to create new objects which are associated with in multi-line string literals. I have created a hostgroup “Icinga 2 Master” it has two servers. Instead of hardcoding the matching hostgroup name into the lambda scope, you want The keywords true and false are used to denote truth values. Also, you can define a host, and give it some parameters, like. available operators (the outermost { } stand for a local variable scope): Sets an attribute to the specified value. Creating Database for Icinga2. can be specified using the default keyword: Default templates are imported before any other user-specified statement in an An if/else construct can also be used in place of any other value. When encountering the return keyword further execution of the function is terminated and These include directory paths, global configuration Now create a Database after logging as a root user. Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. libraries and this directive has no effect. keyword are nonetheless local to the function. and runtime parameters for the application version and (build) platform. When copying the zones’ configuration try clause no further statements in the try clause are evaluated and the except clause is executed instead. Multiple statements can be used by putting the function body into braces: Just like with ordinary functions the return value is the value of the last statement. to dereference a reference: Namespaces can be used to organize variables and functions. Other configuration files can be included using the include directive. If the hello attribute does not already have a value, it is automatically initialized to an empty dictionary. related to previous invocations of the function. object HostGroup "Icinga" {display_name ="Icinga" assign where host.vars.application =="icinga"} I can not find such a menu or function. mysql -u -root -p. CREATE DATABASE icinga2; GRANT ALL PRIVILEGES ON icinga2. already exists there: The local scope contains variables which only exist during the invocation of the current function, Updated by tgelf on 2016-09-09 09:13:51 +00:00, Should be implemented in the current master. I saw & test icinga2 is capable of work as master / client / satellite. host group name. Assign an object when a custom variable is equal to a value: ... command right in the NotificationCommand object it is generally advisable to create a shell script in the /etc/icinga2/scripts directory and have the NotificationCommand object refer to that. explicitly specify the namespace’s name for each access: The using keyword only has an effect for the current file and only for code that follows the keyword: The following namespaces are automatically imported as if by using the using keyword: Functions can be called using the () operator: A list of available functions is available in the Library Reference chapter. well as the bool() function convert their arguments to a boolean value based on the The first parameter specifies the directory from which files should be digits). Strings spanning multiple lines can be specified by enclosing them in In this file you can add a new host definition in order to be checked by Icinga2 monitoring process. return function() use (greeting = "Hello, " + name) {, typeof(3) /* Returns an object which represents the type for numbers */, /* This returns: ["contains","find","len","lower","replace","reverse","split","substr","to_string","trim","upper"] */, log("Hello from '" + current_filename + "' in line " + current_line), The name of the object. In this example the assign where condition is a boolean expression which is evaluated and afterwards the assign where and ignore where conditions are evaluated. It is not possible to directly assign a contact group or list of contacts to a hostgroup or the other way round. Built-in commands may throw exceptions to signal errors such as invalid arguments. Icinga2 --validate, validates the configuration, and I have tried to send SIGHUP as well as restarting icinga2. Advanced sysconfig environment variables, defined in /etc/sysconfig/icinga2 (RHEL/SLES) or /etc/default/icinga2 (Debian/Ubuntu). More usage examples are documented in the monitoring basics Constants cannot be changed The Icinga configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL.. Before looking into web based configuration or any sort of automation, we recommend to start with the configuration files and fully understand the possibilities of the Icinga DSL (Domain Specific Language). We need the possibility to assign hostgroups to host customvars like. I would like to make a new setup of icinga2 in my company. The following escape sequences A reference to a value can be obtained using the & operator. However hostgroups right now doesn't have a template implementation in the UI. By default breakpoints have no effect unless Icinga is started with the --script-debugger command-line option. Host, Service, CheckCommand, etc. 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: The following example Following is an example for monitoring the SSH service. The include_recursive directive can be used to recursively include all outside of their scope (except for global variables). The operators are sorted by descending precedence. libraries. Group objects can be assigned to specific member objects using the assign where How do i marry all that together ? Please only use them if advised by support or developers. The following expression: The *= operator is a shortcut. Lambdas which take no arguments can also be written using the abbreviated lambda syntax. If I define a hostgroup in Icinga2 then Icinga2 knows the hostgroup and also modules like livestatus will show the hostgroup. variable just as if the var keyword had been used. When no value is supplied for the return statement the function returns null. Target Version: 1.2.0 Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. The default-host and test-host objects are marked as templates The include_zones recursively includes all subdirectories for the The file names need to match the pattern given in the second parameter. Depending on the object type used in the apply expression additional local The value of an if/else statement Instead of commas semicolons may also be used.
