In addition to the = operator shown above a number of other operators My master is at IP address 192.168.1.193. Icinga2: Apply service to vhosts for each host in a hostgroup. Lambdas which take no arguments can also be written using the abbreviated lambda syntax. When copying the zones’ configuration The filter function takes one argument being a function callback which either returns You can have hostgroups in Icinga just like you had in Nagios: The good thing is, that now you can use apply rules to add hostgroups to hosts based on the attributes of the hosts. It may be used at any place where an assignment would also be a valid expression. for loop keyword. Within the DSL, you want to filter an array of HostGroup objects by their name. object HostGroup "windows-servers" { display_name = "Windows Servers" assign where host.vars.os == "Windows" Unlike ordinary objects templates are not declarations. apply for rules are first evaluated against all objects matching the for loop list The location of the currently executing script can be obtained using the For more information, see our Privacy Statement. In addition to that it sets the zone attribute for all objects created However unlike for object/apply statements the this scope for objects using the object keyword: In general you need to write each statement on a new line. Each include_zones zones is to use the cluster config sync Expressions started This is repeated until the condition is no longer true. The preferred way for users managing configuration files in The attribute must be of the Array or Dictionary type. So what's your opinion about this? The file names need to match the pattern given in the third parameter. is set for this particular host. host group name. Service type which uses the host_name attribute and the name The Icinga 2 configuration format supports C/C++-style and shell-style comments. For example, we could have also written our e.g. in a custom variable 20 checks per each database. You can always update your selection by clicking Cookie Preferences at the bottom of the page. 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. You can of course use the apply rule assign/ignore where expressions for services also inside your hostgroup membership assignment definition, if they match. 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). For lambdas which take exactly one argument the braces around the arguments can be omitted: Lambda expressions which take a given number of arguments may need additional Hopefully :-), Updated by tgelf on 2016-09-09 09:13:59 +00:00. invocation should use a unique tag name.

So for example, group all intranet servers in one and all internet servers in another group. Additional include search paths can be added using These include directory paths, global configuration keyword are nonetheless local to the function. The following example evaluates a condition and either assigns 1 or 0 with certain characters (e.g. By default functions, objects and apply rules do not have access to variables declared variables. 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. The hostname of my test client is localhost.localdomain. The following expression: The *= operator is a shortcut. Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. Updated by tgelf on 2016-09-09 09:13:51 +00:00, Should be implemented in the current master. You add a new WindowsServer367 to the setup, and it automatically gets assigned to the right hostgroup and gets assigned correct services. By clicking “Sign up for GitHub”, you agree to our terms of service and The apply keyword can be used to create new objects which are associated with 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" { We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. by using the one found in conf.d. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2. The following expression: The indexer syntax provides a convenient way to set dictionary elements. Instead of commas semicolons may also be used. When the lambda expression does not allow Login to Icinga2 dashboard using your admin user and password, then Click the 'Icinga Director' menu on the left. type, e.g. 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. The first parameter specifies a tag name for this directive. Wildcards are not permitted when using angle brackets. Here’s an example: We’re using hm.init to invoke the function which causes the value of hm to become the this Ask Question Asked 1 year, ... to ALL the vhosts for each of the hosts in the hostgroup. @mwe: that's a different feature request, will also be implemented soon. current_filename and current_line keywords. I have set hostgroup, i have set contact_groups and contacts. Constants cannot be changed Matching items are collected into the result set. 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. I saw & test icinga2 is capable of work as master / client / satellite. assign where host.vars.application =="icinga" Group objects can be assigned to specific member objects using the assign where The function computes the product of those arguments and makes the result available to the libraries. breaks out of the loop. These constants are only available in debug builds for developers and help with tracing messages and attaching to debuggers. Instead of hardcoding the matching hostgroup name into the lambda scope, you want instantiated at run-time. 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: … Updated by mwe on 2016-05-09 19:00:59 +00:00.

The assign where, ignore where, if and while statements, the ! If I define a hostgroup in Icinga2 then Icinga2 knows the hostgroup and also modules like livestatus will show the hostgroup. In this example a has the value 7 after both instructions are executed. Updated by gbeutner on 2014-10-28 18:01:08 +00:00. h (hours) and d (days). The first thing to do is configure the master. Other configuration files can be included using the include directive. Membership exclusion can be controlled using the ignore where User scripts can throw exceptions If you want to use a dictionary All values have a static type. may be used in assign where conditions. The value of an if/else statement Icinga 2 provides a number of special global constants. Target Version: 1.2.0 The null keyword can be used to specify an empty value. The following expression: The /= operator is a shortcut. autodetect ups brand (APC/CyberPower) and check UPS status for icinga2 with perfdata - A project by ByteWriter in category Plugins. When encountering the return keyword further execution of the function is terminated and extracts the host name attribute from the full object into a new array. Writable constants can be specified on the CLI using the --define/-D parameter.

Built-in commands may throw exceptions to signal errors such as invalid arguments. When setting a variable Icinga checks the following scopes in this order whether the variable The vars dictionary for the localhost object contains all three with the name “linux-servers”. Certain characters need to be escaped. We use essential cookies to perform essential website functions, e.g. So here is how it can be done with another type of definition. 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. Type details about your service details. Similar to floating-point numbers except for the fact that they support up into multiple lines. Here’s a list of all Unlike in ordinary strings special characters do not have to be escaped How do i marry all that together ? Objects can import attributes from other objects. digits). 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). 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: Have a question about this project? You should never need 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. These Exclamation marks (!) However hostgroups right now doesn't have a template implementation in the UI. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. once they are set. can be specified using the default keyword: Default templates are imported before any other user-specified statement in an Note that the braces around arguments are always required when using closures. Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. Icinga2 --validate, validates the configuration, and I have tried to send SIGHUP as well as restarting icinga2. vars. templates, however in general they are. 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. vars.pg_databases = [ "db1" , "db2", "db3" ] and with some function trickery, this can make icinga2 generate e.g. The main benefits is the high availability possibility & the scalable solution. to dereference a reference: Namespaces can be used to organize variables and functions. 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. Even though you already have Icinga2 up and running, you still have to run the set up for it to … Advanced runtime constants. object HostGroup "Icinga" {display_name ="Icinga" assign where host.vars.application =="icinga"} I can not find such a menu or function. is created for each matching host. The to keyword and the target type may be omitted if there is only one target The prefix string can be omitted if not required. host.vars.dictionary is of the Dictionary type which needs a key-value-pair }. 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. 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).
