The comma after the last key-value pair is optional. Make sure you choose a secure password! keyword are nonetheless local to the function. zones is to use the cluster config sync they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. 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. are supported: In addition to these pre-defined escape sequences you can specify Each type has an associated type object which describes the type’s semantics. Icinga 2 features an object-based configuration format. The hostname of my master is ubuntu16.04 (issue the command less /etc/hosts to find yours). files in a directory which match a certain pattern. The key and value variables can be used for object attribute assignment, e.g. I have set hostgroup, i have set contact_groups and contacts. So here is how it can be done with another type of definition. Already on GitHub? Individual array elements must be comma-separated. apply for rules are first evaluated against all objects matching the for loop list When the lambda expression does not allow value of the name function argument. to dereference a reference: Namespaces can be used to organize variables and functions. Matching items are collected into the result set. in multi-line string literals. import keyword. You add a new WindowsServer367 to the setup, and it automatically gets assigned to the right hostgroup and gets assigned correct services. to the local variable. The first thing to do is configure the master. construct can be used to accomplish this. Variables declared without the var How do I write that assign where statement? them with a semicolon: Each object is uniquely identified by its type (Host) and name Last Update: 2016-09-09 09:13:59 +00:00 (in Redmine), We need the possibility to assign hostgroups to host customvars like, object HostGroup "Icinga" { Icinga 2 provides a number of special global constants. @mwe: that's a different feature request, will also be implemented soon. to control the value from the outside configuration values, e.g. Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. Then I created a Hostgroup “Icinga 2 Backend” which has a hostgroup included (Icinga 2 Master) In detail: object HostGroup “hg_icinga2_master” {display_name = “Icinga 2 Master” assign where host.name == “ici2-m1.local” || host.name == “ici2-m2.local”} Parent objects do not necessarily have to be scope for this function call. suffixes to help with specifying time durations. evaluated for all objects of type Host and a new service with name “ping” 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: This creates a new function which returns the value 3. The null keyword can be used to specify an empty value. Functions which do not have a return statement have their return value set to the value of the invocation should use a unique tag name. related to previous invocations of the function. Functions also have a this scope. operator as Built-in commands may throw exceptions to signal errors such as invalid arguments. are treated like numeric literals. Learn more. Expression operators may be used in assign where and Constants cannot be changed (host1.example.org). The keywords true and false are used to denote truth values. Hello, I'm monitoring 4 servers + localhost. Apply rules can be extended with the Default paths which include /etc and /var as base directory continue to work The filter function takes one argument being a function callback which either returns host.vars.dictionary is of the Dictionary type which needs a key-value-pair Icinga also supports include search paths similar to how they work in a In order to create a new value of a specific type constructor calls may be used. templates, however in general they are. Note that this example makes use of the map method for the Array type which Relations: duplicates #11330; Copy link Quote reply Member Author 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. Objects can contain a comma-separated list of property @essener61: you're right, that's missing. 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. The icinga https://www.icinga.com/docs/icinga2/latest/doc/03-monitoring-basics/#groups. When no pattern is specified the default pattern “*.conf” is used. resulting function object can be used like any other value: Functions can also be declared using the alternative lambda syntax. 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' ], } … Ask Question Asked 1 year, ... to ALL the vhosts for each of the hosts in the hostgroup. The continue and break keywords can be used to control how the loop is executed: The continue keyword Target Version: 1.2.0 When copying the zones’ configuration The hostname of my test client is localhost.localdomain. check_interval = 30 // this is also a comment. The default-host and test-host objects are marked as templates libraries and this directive has no effect. By default $PREFIX/share/icinga2/include is included in the list of search But I need split view by responsability domain. Package Repository. Note that the braces around arguments are always required when using closures. We use essential cookies to perform essential website functions, e.g. This is repeated until the condition is no longer true. The comma after the last element is optional. custom variables and the custom variable colour has the value "blue". objects using the object keyword: In general you need to write each statement on a new line. command-line options. Here’s a list of all I have created a hostgroup “Icinga 2 Master” it has two servers. For more information, see our Privacy Statement. It is not possible to directly assign a contact group or list of contacts to a hostgroup or the other way round. The check_interval attribute paths. 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. may be used in assign where conditions. object or apply statement. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Values are separated with a colon : character. using the throw keyword. Individual key-value pairs must either be comma-separated or on separate lines. If you want to use a dictionary In this example 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. Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. Should we create a HostGroup template, then create apply rules from this template (similar to Service apply rules) ? You can define new breaks out of the loop. The apply keyword can be used to create new objects which are associated with Additional examples with advanced condition chaining: The while statement checks a condition and executes the loop body when the condition evaluates to true. privacy statement. Context: I use icinga2 to monitor most of my servers and (home/office) routers. Is it a bug or feature? as iterator. with the name “linux-servers”. When encountering the return keyword further execution of the function is terminated and C/C++ compiler: Note the use of angle brackets instead of double quotes. For example, host.address would return the value of the host’s Alternatively you can write multiple statements on a single line by separating You can escape reserved keywords using the @ character. The location of the currently executing script can be obtained using the compared in a case-sensitive manner. with certain characters (e.g. Exceptions can be handled using the try and except keywords. config compiler to search the include search paths for the specified Have a question about this project? the keyword is used to create a new namespace: The namespace is made available as a global variable which has the namespace’s name (e.g. As this is only for testing purposes, it's okay to use localhost.localdomain. /var/lib/icinga2/api/config. To create a new service template, click the 'Add' button. You should never need An unordered list of key-value pairs. up into multiple lines. outside of their scope (except for global variables). I saw & test icinga2 is capable of work as master / client / satellite. The assign where, ignore where, if and while statements, the ! Status: Resolved (closed on 2016-09-09 09:13:59 +00:00) Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. chapter. include directive. They are used to avoid name conflicts. This causes the Keys must be unique and are The namespace Sign in 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. in these subdirectories to the name of the subdirectory. If there are multiple default templates the order in which they are imported 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 ). We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Membership exclusion can be controlled using the ignore where Icinga2: Apply service to vhosts for each host in a hostgroup. a function is set to whichever object was used to invoke the function. last expression which was performed by the function. Additional include search paths can be added using Group objects can be assigned to specific member objects using the assign where Utils): The using keyword can be used to make all attributes in a namespace available to a script without having to by using the one found in conf.d. object HostGroup "Icinga" {display_name ="Icinga" assign where host.vars.application =="icinga"} I can not find such a menu or function. The first parameter specifies a tag name for this directive. Any valid config attribute can be accessed using the host and service The constants below have been used until Icinga v2.10, and are still intact. is created for each matching host. If this is the first time you are installing MySQL you’ll need to choose a root password. by an ASCII character in octal encoding. Updated by mwe on 2016-05-09 19:00:59 +00:00. These include directory paths, global configuration Instead of if/else condition chains, you can also use the ternary operator ? Service type which uses the host_name attribute and the name The * operator can be used declarations. User scripts can throw exceptions Unlike ordinary objects templates are not file. When no pattern is specified the default pattern “*.conf” is used. Unlike in ordinary strings special characters do not have to be escaped In this example the assign where condition is a boolean expression which is Start simple with just one HostGroup, e.g. The first parameter specifies the directory from which files should be well as the bool() function convert their arguments to a boolean value based on the You signed in with another tab or window. 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 Hello, We are starting to try a Dashing and try to show data only for some Hostgroups/Servicegroups. This is an internal functionality consumed by Icinga itself. Iterating over dictionaries can be accomplished in a similar manner: The var keyword is optional when declaring variables in the loop’s header. But IcingaWeb2 does not show the group. The debugger keyword can be used to insert a breakpoint. In addition to that it sets the zone attribute for all objects created The operators are sorted by descending precedence. 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). Each include_zones These keywords are reserved and must not be used as constants or custom variables. In this example all generated service object names consist of prefix- and 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 value of an if/else statement The following expression: The *= operator is a shortcut. Expression operators The += operator is a shortcut. recursively included. All values have a static type. to manipulate attributes are supported. Configuration ¶. based on the SysconfDir and LocalStateDir constants respectively. Do not, however, use this for your servers. The Icinga 2 configuration format supports C/C++-style and shell-style comments. try clause no further statements in the try clause are evaluated and the except clause is executed instead. with assignments.

In addition to the = operator shown above a number of other operators First, define a group of hosts for each group of admins. Functions can be defined using the function keyword. variables. Identifiers may not contain certain characters (e.g. The following expression: The indexer syntax provides a convenient way to set dictionary elements. A reference to a value can be obtained using the & operator. * local variable `check_interval` would have been modified instead. branch value is returned. setting the check_command attribute or custom variables as command parameters. and ignore where conditions. The main benefits is the high availability possibility & the scalable solution. variables. 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. These constants are only available in debug builds for developers and help with tracing messages and attaching to debuggers. Whether the first condition matches, the first value is returned, if not, the else and second You don’t have to define them explicitly anymore.

The this scope refers to the current object which the function or object/apply statement variable values from the outer scope. Duration literals are converted to seconds by the config parser and We’ll occasionally send you account related emails. We need the possibility to assign hostgroups to host customvars like. h (hours) and d (days). Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. 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). the specified value is supplied to the caller of the function: In this example the multiply function we declared earlier is invoked with two arguments (3 and 5). Since icinga collects "perfdata" (performance data) and supports sending that data to Graphite, I then use Grafana to produce graphics of the network usage on my network. statements, see expression operators.
