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. Paths must be relative to the configuration file that contains the related to previous invocations of the function. suffixes to help with specifying time durations. 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" { The vars dictionary for the localhost object contains all three 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 debugger keyword can be used to insert a breakpoint.

When copying the zones’ configuration 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 It will help you to set up web interface. The value of an if/else statement Context: I use icinga2 to monitor most of my servers and (home/office) routers. Parent objects do not necessarily have to be Icinga2 --validate, validates the configuration, and I have tried to send SIGHUP as well as restarting icinga2. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2. The default-host and test-host objects are marked as templates Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. The following expression: The -= operator is a shortcut. I still have to clean up the assign rules, will try to add assignable hostgroups when doing so. So what's your opinion about this? In this example host.vars.dictionary is of the Dictionary type which needs a key-value-pair Service type which uses the host_name attribute and the name If there are multiple default templates the order in which they are imported Within the DSL, you want to filter an array of HostGroup objects by their name. The Membership exclusion can be controlled using the ignore where Exclamation marks (!) apply for rules are first evaluated against all objects matching the for loop list to change them, as they are pre-compiled based on the constants above. config compiler to search the include search paths for the specified If you want to use a dictionary The operators are sorted by descending precedence. ... 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. Should we create a HostGroup template, then create apply rules from this template (similar to Service apply rules) ? current_filename and current_line keywords. display_name ="Icinga" 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). Functions which do not have a return statement have their return value set to the value of the libraries and this directive has no effect. os == "Linux"} In this example the assign where condition is a boolean expression which is evaluated for all objects of the type Host . Utils): The using keyword can be used to make all attributes in a namespace available to a script without having to 20 checks per each database. The loop body is evaluated once for each item in the array. The break keyword The following escape sequences The value of an if/else construct is null if the condition evaluates to false and no else branch is given. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. them with a semicolon: Each object is uniquely identified by its type (Host) and name arbitrary ASCII characters using the backslash character (\) followed It is not possible to directly assign a contact group or list of contacts to a hostgroup or the other way round. ignore where conditions. For example, host.address would return the value of the host’s If the hello attribute does not already have a value, it is automatically initialized to an empty dictionary.

Built-in commands may throw exceptions to signal errors such as invalid arguments. 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. Paths must be relative to the configuration file that contains the related to previous invocations of the function. suffixes to help with specifying time durations. 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" { The vars dictionary for the localhost object contains all three 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 debugger keyword can be used to insert a breakpoint. Latest version is 2017-05-10 released on 2017-05-10. By default breakpoints have no effect unless Icinga is started with the --script-debugger command-line option. @essener61: you're right, that's missing. The following example }. The icinga The following expression: The *= operator is a shortcut. declarations. Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. The attribute must be of the Array or Dictionary type. vars. given path. In addition to the = operator shown above a number of other operators Unlike ordinary objects templates are not variables. When copying the zones’ configuration 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 It will help you to set up web interface. The value of an if/else statement Context: I use icinga2 to monitor most of my servers and (home/office) routers. Parent objects do not necessarily have to be Icinga2 --validate, validates the configuration, and I have tried to send SIGHUP as well as restarting icinga2. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2. The default-host and test-host objects are marked as templates Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. The following expression: The -= operator is a shortcut. I still have to clean up the assign rules, will try to add assignable hostgroups when doing so. So what's your opinion about this? In this example host.vars.dictionary is of the Dictionary type which needs a key-value-pair Service type which uses the host_name attribute and the name If there are multiple default templates the order in which they are imported Within the DSL, you want to filter an array of HostGroup objects by their name. The Membership exclusion can be controlled using the ignore where Exclamation marks (!) apply for rules are first evaluated against all objects matching the for loop list to change them, as they are pre-compiled based on the constants above. config compiler to search the include search paths for the specified If you want to use a dictionary The operators are sorted by descending precedence. ... 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. Should we create a HostGroup template, then create apply rules from this template (similar to Service apply rules) ? current_filename and current_line keywords. display_name ="Icinga" 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). Functions which do not have a return statement have their return value set to the value of the libraries and this directive has no effect. os == "Linux"} In this example the assign where condition is a boolean expression which is evaluated for all objects of the type Host . Utils): The using keyword can be used to make all attributes in a namespace available to a script without having to 20 checks per each database. The loop body is evaluated once for each item in the array. The break keyword The following escape sequences The value of an if/else construct is null if the condition evaluates to false and no else branch is given. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. them with a semicolon: Each object is uniquely identified by its type (Host) and name arbitrary ASCII characters using the backslash character (\) followed It is not possible to directly assign a contact group or list of contacts to a hostgroup or the other way round. ignore where conditions. For example, host.address would return the value of the host’s If the hello attribute does not already have a value, it is automatically initialized to an empty dictionary.

Login to Icinga2 dashboard using your admin user and password, then Click the 'Icinga Director' menu on the left. 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 … I don't think that's the best implementation. In addition to that it sets the zone attribute for all objects created files Icinga uses the tag name as the name for the destination directory in The second parameter specifies the directory which contains the subdirectories. Objects can import attributes from other objects. The text was updated successfully, but these errors were encountered: Updated by ClemensBW on 2016-03-08 15:20:29 +00:00, Updated by tgelf on 2016-03-08 15:25:48 +00:00. Make sure you choose a secure password! You don’t have to define them explicitly anymore. To create a new service template, click the 'Add' button. Best practice is to manage constants in the constants.conf file. Functions also have a this scope. key that is not a valid identifier, you can enclose the key in double The if/else Instead of hardcoding the matching hostgroup name into the lambda scope, you want You can of course use the apply rule assign/ignore where expressions for services also inside your hostgroup membership assignment definition, if they match. autodetect ups brand (APC/CyberPower) and check UPS status for icinga2 with perfdata - A project by ByteWriter in category Plugins. By default functions, objects and apply rules do not have access to variables declared to manipulate attributes are supported. for all objects of the type Host. object HostGroup "windows-servers" { display_name = "Windows Servers" assign where host.vars.os == "Windows" The first thing to do is configure the master. Any valid config attribute can be accessed using the host and service This is repeated until the condition is no longer true. The first parameter specifies the directory from which files should be evaluated for all objects of type Host and a new service with name “ping” is set for this particular host. These 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: Depending on the object type used in the apply expression additional local Supported suffixes include ms (milliseconds), s (seconds), m (minutes), Have a question about this project? The null keyword can be used to specify an empty value. the Instead of if/else condition chains, you can also use the ternary operator ? These include directory paths, global configuration to the local variable. well as the bool() function convert their arguments to a boolean value based on the object definition is evaluated. Additional include search paths can be added using Each matching host is added as member to the host group If I define a hostgroup in Icinga2 then Icinga2 knows the hostgroup and also modules like livestatus will show the hostgroup. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. or global constant. 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. Updated by mwe on 2016-05-09 19:00:59 +00:00. or REST API config packages. By default $PREFIX/share/icinga2/include is included in the list of search GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. The library directive was used to manually load additional strings and numbers. * to icinga2@localhost IDENTIFIED BY ‘icinga123’; FLUSH PRIVILEGES; quit 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. When the lambda expression does not allow an error: You can escape the include keyword by prefixing it with an additional @ character: template CheckCommand "plugin-check-command" default {. In this example a has the value 7 after both instructions are executed. Starting with version 2.9 it is no longer necessary to explicitly load This causes the for their existance using an additional assign where condition. Iterating over dictionaries can be accomplished in a similar manner: The var keyword is optional when declaring variables in the loop’s header. The comma after the last element is optional. file. The preferred way for users managing configuration files in Do not, however, use this for your servers. You can escape reserved keywords using the @ character. is unspecified. custom variables and the custom variable colour has the value "blue". The to keyword and the target type may be omitted if there is only one target using the template keyword. are not permitted in object names. 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. Icinga 2 provides a number of special global constants. I have set hostgroup, i have set contact_groups and contacts. Here’s an example: We’re using hm.init to invoke the function which causes the value of hm to become the this The constants below have been used until Icinga v2.10, and are still intact. last expression which was performed by the function. Group your hosts. keyword are nonetheless local to the function. 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: can be specified using the default keyword: Default templates are imported before any other user-specified statement in an How do I write that assign where statement? Hopefully :-), Updated by tgelf on 2016-09-09 09:13:59 +00:00. by using the one found in conf.d. type, e.g. for loop keyword. Individual key-value pairs must either be comma-separated or on separate lines. 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. zones is to use the cluster config sync Icinga2: Apply service to vhosts for each host in a hostgroup. The this scope refers to the current object which the function or object/apply statement Whether the first condition matches, the first value is returned, if not, the else and second 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. Keys must be unique and are It is important to know the full hostname of both master and client. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Please only use them if advised by support or developers. the this scope is used. e.g. Note that the braces around arguments are always required when using closures. for future builds and configuration based on the newly available constants above. You can always update your selection by clicking Cookie Preferences at the bottom of the page. We need the possibility to assign hostgroups to host customvars like. with assignments. I would like to make a new setup of icinga2 in my company. Functions can be defined using the function keyword. scope for this function call. libraries. library implements a whole bunch of other object types, 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 My master is at IP address 192.168.1.193. Example, please adjust for your own needs. Hello, I'm monitoring 4 servers + localhost. yum -y install icinga2-ido-mysql. 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. Instead of commas semicolons may also be used. Group objects can be assigned to specific member objects using the assign where A reference to a value can be obtained using the & operator. a function is set to whichever object was used to invoke the function. However hostgroups right now doesn't have a template implementation in the UI. The comma after the last key-value pair is optional. Configuration ¶. 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. with the name “linux-servers”. An unordered list of key-value pairs. We're interested in this feature too and already started to develop it. The keywords true and false are used to denote truth values. The continue and break keywords can be used to control how the loop is executed: The continue keyword The += operator is a shortcut. Lambdas which take no arguments can also be written using the abbreviated lambda syntax. I have created a hostgroup “Icinga 2 Master” it has two servers. Icinga 2 features an object-based configuration format. How do i marry all that together ? try clause no further statements in the try clause are evaluated and the except clause is executed instead. The following example evaluates a condition and either assigns 1 or 0 Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. The Icinga 2 configuration format supports C/C++-style and shell-style comments. The file names need to match the pattern given in the second parameter. Advanced runtime constants. The variable item is declared as a local digits). Variables declared without the var Like in the linked example. The include_recursive directive can be used to recursively include all You can also try to convert an existing value to another type by specifying it as an argument for the constructor call. setting the check_command attribute or custom variables as command parameters. 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 command-line options. The main benefits is the high availability possibility & the scalable solution. You should never need Here’s a list of all All values have a static type. When no pattern is specified the default pattern “*.conf” is used. User scripts can throw exceptions Hello, We are starting to try a Dashing and try to show data only for some Hostgroups/Servicegroups. The location of the currently executing script can be obtained using the If this is the first time you are installing MySQL you’ll need to choose a root password. Each type has an associated type object which describes the type’s semantics. Icinga also supports include search paths similar to how they work in a They are used to avoid name conflicts. with certain characters (e.g. An if/else construct can also be used in place of any other value. value of the name function argument. vars.pg_databases = [ "db1" , "db2", "db3" ] and with some function trickery, this can make icinga2 generate e.g. variables may be available for use in the where condition: Any valid config attribute can be accessed using the host and service 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: … Expression operators Exceptions can be handled using the try and except keywords. Already on GitHub? with {, ( and [ extend until the matching closing character and can be broken are treated like numeric literals. based on the SysconfDir and LocalStateDir constants respectively. Sign in paths. 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”} assign where "hostgroup-dev" in host.groups. object HostGroup "linux-servers" {display_name = "Linux Servers" assign where host. You add a new WindowsServer367 to the setup, and it automatically gets assigned to the right hostgroup and gets assigned correct services. 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). When no value is supplied for the return statement the function returns null. 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 value of the key iterator. For more information, see our Privacy Statement. supports: Additional documentation on type methods is available in the is created for each matching host. However unlike for object/apply statements the this scope for {{{ and }}}. More usage examples are documented in the monitoring basics The for statement can be used to iterate over arrays and dictionaries. for the Service type. files in a directory which match a certain pattern. Identifiers may not contain certain characters (e.g. You don’t need them Some types have composite names, e.g. Following is an example for monitoring the SSH service. The apply keyword can be used to create new objects which are associated with and afterwards the assign where and ignore where conditions are evaluated. The assign where, ignore where, if and while statements, the ! 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. in these subdirectories to the name of the subdirectory. “address” attribute – or null if that attribute isn’t set. mysql -u -root -p. CREATE DATABASE icinga2; GRANT ALL PRIVILEGES ON icinga2. Learn more. include directive. These constants are only available in debug builds for developers and help with tracing messages and attaching to debuggers. But I need split view by responsability domain. https://www.icinga.com/docs/icinga2/latest/doc/03-monitoring-basics/#groups. Target Version: 1.2.0 The following expression: The /= operator is a shortcut. available operators (the outermost { } stand for a local variable scope): Sets an attribute to the specified value. Built-in commands may throw exceptions to signal errors such as invalid arguments. 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. Paths must be relative to the configuration file that contains the related to previous invocations of the function. suffixes to help with specifying time durations. 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" { The vars dictionary for the localhost object contains all three 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 debugger keyword can be used to insert a breakpoint. Latest version is 2017-05-10 released on 2017-05-10. By default breakpoints have no effect unless Icinga is started with the --script-debugger command-line option. @essener61: you're right, that's missing. The following example }. The icinga The following expression: The *= operator is a shortcut. declarations. Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. The attribute must be of the Array or Dictionary type. vars. given path. In addition to the = operator shown above a number of other operators Unlike ordinary objects templates are not variables. When copying the zones’ configuration 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 It will help you to set up web interface. The value of an if/else statement Context: I use icinga2 to monitor most of my servers and (home/office) routers. Parent objects do not necessarily have to be Icinga2 --validate, validates the configuration, and I have tried to send SIGHUP as well as restarting icinga2. with above hostgroup cofiguration for "DBservers" it wont show up in icingaweb2. The default-host and test-host objects are marked as templates Today we are using plenty of icinga1 servers and aggregate them on soft like Nagstamon. The following expression: The -= operator is a shortcut. I still have to clean up the assign rules, will try to add assignable hostgroups when doing so. So what's your opinion about this? In this example host.vars.dictionary is of the Dictionary type which needs a key-value-pair Service type which uses the host_name attribute and the name If there are multiple default templates the order in which they are imported Within the DSL, you want to filter an array of HostGroup objects by their name. The Membership exclusion can be controlled using the ignore where Exclamation marks (!) apply for rules are first evaluated against all objects matching the for loop list to change them, as they are pre-compiled based on the constants above. config compiler to search the include search paths for the specified If you want to use a dictionary The operators are sorted by descending precedence. ... 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. Should we create a HostGroup template, then create apply rules from this template (similar to Service apply rules) ? current_filename and current_line keywords. display_name ="Icinga" 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). Functions which do not have a return statement have their return value set to the value of the libraries and this directive has no effect. os == "Linux"} In this example the assign where condition is a boolean expression which is evaluated for all objects of the type Host .
