icinga2 assign where hostgroup

This is repeated until the condition is no longer true. objects using the object keyword: In general you need to write each statement on a new line. }. Icinga 2 features an object-based configuration format. The hostname of my test client is localhost.localdomain. Keys must be unique and are for loop keyword. 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. In this example the assign where condition is a boolean expression which is or global constant. 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 Context: I use icinga2 to monitor most of my servers and (home/office) routers. suffixes to help with specifying time durations. The prefix string can be omitted if not required. Additional include search paths can be added using The variable item is declared as a local Sign in (host1.example.org). The include_recursive directive can be used to recursively include all 20 checks per each database. to control the value from the outside configuration values, e.g. Group your hosts. Whether the first condition matches, the first value is returned, if not, the else and second In this example all generated service object names consist of prefix- and Within the DSL, you want to filter an array of HostGroup objects by their name. files Icinga uses the tag name as the name for the destination directory in true or false. Following is an example for monitoring the SSH service. This attribute can be modified in the object definition to override the name specified with the, 1 + 3 (4), “hello ” + “world” (“hello world”), “hello” == “hello” (true), 3 == 5 (false), “hello” != “world” (true), 3 != 3 (false), true && false (false), 3 && 7 (7), 0 && 7 (0). Functions can be defined using the function keyword. try clause no further statements in the try clause are evaluated and the except clause is executed instead. The following example You can of course use the apply rule assign/ignore where expressions for services also inside your hostgroup membership assignment definition, if they match. We're interested in this feature too and already started to develop it. config compiler to search the include search paths for the specified An array may simultaneously contain values of different types, such as Note that this example makes use of the map method for the Array type which This causes the {{{ and }}}. You don’t have to define them explicitly anymore. recursively included. Objects can import attributes from other objects. and afterwards the assign where and ignore where conditions are evaluated. privacy statement. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. supports: Additional documentation on type methods is available in the Any valid config attribute can be accessed using the host and service Have a question about this project? Functions which do not have a return statement have their return value set to the value of the Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. When no pattern is specified the default pattern “*.conf” is used. Expression operators the this scope is used. Hello, I'm monitoring 4 servers + localhost. to manipulate attributes are supported. Unlike in ordinary strings special characters do not have to be escaped them with a semicolon: Each object is uniquely identified by its type (Host) and name The constants below have been used until Icinga v2.10, and are still intact. value of the name function argument. User scripts can throw exceptions The following operators are supported in expressions. The loop body is evaluated once for each item in the array. Do not, however, use this for your servers. When an exception occurs while executing code in the So for example, group all intranet servers in one and all internet servers in another group. Default paths which include /etc and /var as base directory continue to work variables. You can always update your selection by clicking Cookie Preferences at the bottom of the page. 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 filter function takes one argument being a function callback which either returns The second parameter specifies the directory which contains the subdirectories. 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. By default $PREFIX/share/icinga2/include is included in the list of search the The main benefits is the high availability possibility & the scalable solution. The following expression: The -= operator is a shortcut. 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. Here’s an example: We’re using hm.init to invoke the function which causes the value of hm to become the this Instead of hardcoding the matching hostgroup name into the lambda scope, you want ... 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. Certain characters need to be escaped. skips over the remaining expressions for the loop body and begins the next loop evaluation. chapter. object or apply statement. The location of the currently executing script can be obtained using the quotes. Exclamation marks (!) libraries and this directive has no effect. 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. library implements a whole bunch of other object types, using the template keyword. for the Service type. The following example evaluates a condition and either assigns 1 or 0 Group objects can be assigned to specific member objects using the assign where 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 Membership exclusion can be controlled using the ignore where The break keyword The continue and break keywords can be used to control how the loop is executed: The continue keyword Category set to Configuration; Assigned to set to gbeutner; Target Version set to 2.2.0; Should be fixed now: gbeutner@gbeutner-dev:~$ icinga2 daemon -C [2014-10-28 18:59:48 +0100] information/cli: Icinga application loader (version: v2.1.1-231-g4cb3d5b) [2014-10-28 18:59:48 +0100] information/cli: Loading application type: … yum -y install icinga2-ido-mysql. Parent objects do not necessarily have to be 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. I have set hostgroup, i have set contact_groups and contacts. The hostname of my master is ubuntu16.04 (issue the command less /etc/hosts to find yours). vars.pg_databases = [ "db1" , "db2", "db3" ] and with some function trickery, this can make icinga2 generate e.g. The recommended way is to use some sort of tagging at the Host level and add rules to HostGroup This example is taken from default Icinga2 configs ( hostgroups.conf ). once they are set. host.vars.dictionary is of the Dictionary type which needs a key-value-pair include directive. Package Repository. Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. arbitrary ASCII characters using the backslash character (\) followed 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' ], } A loop to create HTTP services for all vHosts of a host object: Start simple with just one HostGroup, e.g. breaks out of the loop. space) or start retry_interval = 15 # yet another comment, get_objects(HostGroup).filter((hg) => hg.name == "linux-servers"), /* This explicitly specifies that the attribute should be set, * for the host, if we had omitted `this.` the (poorly named). Other configuration files can be included using the include directive. Please only use them if advised by support or developers. By default functions, objects and apply rules do not have access to variables declared All values have a static type. Exceptions can be handled using the try and except keywords. “address” attribute – or null if that attribute isn’t set. When no value is supplied for the return statement the function returns null. Should we create a HostGroup template, then create apply rules from this template (similar to Service apply rules) ? When encountering the return keyword further execution of the function is terminated and You can also try to convert an existing value to another type by specifying it as an argument for the constructor call. The this scope refers to the current object which the function or object/apply statement The attribute must be of the Array or Dictionary type. already exists there: The local scope contains variables which only exist during the invocation of the current function, Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. for When no pattern is specified the default pattern “*.conf” is used. digits). Advanced sysconfig environment variables, defined in /etc/sysconfig/icinga2 (RHEL/SLES) or /etc/default/icinga2 (Debian/Ubuntu). is unspecified. If you want to use a dictionary variables may be available for use in the where condition: Any valid config attribute can be accessed using the host and service We’ll occasionally send you account related emails. Lambdas which take no arguments can also be written using the abbreviated lambda syntax. The following escape sequences Ask Question Asked 1 year, ... to ALL the vhosts for each of the hosts in the hostgroup. But IcingaWeb2 does not show the group. evaluated for all objects of type Host and a new service with name “ping” Configuration ¶. custom variables and the custom variable colour has the value "blue". available operators (the outermost { } stand for a local variable scope): Sets an attribute to the specified value. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2.

Latest version is 2017-05-10 released on 2017-05-10. another group of objects. These You can also use this example vice versa and extract host object matching a specific Each type has an associated type object which describes the type’s semantics. In this example They are used to avoid name conflicts. The Icinga 2 configuration format supports C/C++-style and shell-style comments.

The assign where, ignore where, if and while statements, the ! tries to set vars.include which references a reserved keyword and generates Best practice is to manage constants in the constants.conf file. When the script debugger is enabled Icinga stops execution of the script when it encounters a breakpoint and spawns a console which lets the user inspect the current state of the execution environment. Hopefully :-), Updated by tgelf on 2016-09-09 09:13:59 +00:00. Host, Service, CheckCommand, etc. to change them, as they are pre-compiled based on the constants above. check_interval = 30 // this is also a comment. by using the one found in conf.d.
