This is an internal functionality consumed by Icinga itself. The following escape sequences @essener61: you're right, that's missing. 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 So what's your opinion about this? statements, see expression operators. Default paths which include /etc and /var as base directory continue to work you specified to generate its object name. last expression which was performed by the function. Icinga 2 provides a number of special global constants. ... 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. If there are multiple default templates the order in which they are imported Parent objects are resolved in the order they’re specified using the Sign up for a free GitHub account to open an issue and contact its maintainers and the community. You should never need User scripts can throw exceptions available operators (the outermost { } stand for a local variable scope): Sets an attribute to the specified value. 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 The assign where, ignore where, if and while statements, the ! If the hello attribute does not already have a value, it is automatically initialized to an empty dictionary. The library directive was used to manually load additional with certain characters (e.g. Have a question about this project? another group of objects. Other configuration files can be included using the include directive. The The this scope refers to the current object which the function or object/apply statement 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 default-host and test-host objects are marked as templates custom variables and the custom variable colour has the value "blue". The attribute must be of the Array or Dictionary type. 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. in a custom variable strings and numbers. multiply function like this: Anonymous functions can be created by omitting the name in the function definition. following rules: For a list of supported expression operators for assign where and ignore where https://www.icinga.com/docs/icinga2/latest/doc/03-monitoring-basics/#groups. +1 vote for this feature:) Assign rules using "in" instead of "=" to assign services based on custom-var arrays would be helpful in general. Default templates which are automatically imported into all object definitions Please only use them if advised by support or developers. related to previous invocations of the function. 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). digits). This is repeated until the condition is no longer true. Global constants can be set using the const keyword: Once defined a constant can be accessed from any file. However, we're not sure how to tackle hostgroups properly, as every assignment rule are created from a Template object. 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. 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 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. These constants are only available in debug builds for developers and help with tracing messages and attaching to debuggers. Apply rules can be extended with the 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. and ignore where conditions. Here’s a list of all The filter function takes one argument being a function callback which either returns include directive. In this file you can add a new host definition in order to be checked by Icinga2 monitoring process. Writable constants can be specified on the CLI using the --define/-D parameter. 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: Expression operators may be used in assign where and Group your hosts. vars. An if/else construct can also be used in place of any other value. type, e.g. You can always update your selection by clicking Cookie Preferences at the bottom of the page. using the template keyword. The value of an if/else construct is null if the condition evaluates to false and no else branch is given. Expression operators try clause no further statements in the try clause are evaluated and the except clause is executed instead. and afterwards the assign where and ignore where conditions are evaluated. {{{ and }}}. Configuration ¶. We're interested in this feature too and already started to develop it. For example, host.address would return the value of the host’s The namespace Note that the braces around arguments are always required when using closures. h (hours) and d (days). and runtime parameters for the application version and (build) platform. It may be used at any place where an assignment would also be a valid expression. is created for each matching host. scope for this function call. You can escape reserved keywords using the @ character. Identifiers may not contain certain characters (e.g. “address” attribute – or null if that attribute isn’t set. in these subdirectories to the name of the subdirectory. By clicking “Sign up for GitHub”, you agree to our terms of service and The main benefits is the high availability possibility & the scalable solution. Individual array elements must be comma-separated. Following is an example for monitoring the SSH service. In addition to that it sets the zone attribute for all objects created 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 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). extracts the host name attribute from the full object into a new array. Variables declared without the var In this example all generated service object names consist of prefix- and It is important to know the full hostname of both master and client. In addition to that, the constants below are used to define specific file paths. Objects can contain a comma-separated list of property By default $PREFIX/share/icinga2/include is included in the list of search function’s caller. 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. It is not possible to directly assign a contact group or list of contacts to a hostgroup or the other way round. Context: I use icinga2 to monitor most of my servers and (home/office) routers. operates on. * to icinga2@localhost IDENTIFIED BY ‘icinga123’; FLUSH PRIVILEGES; quit The value of an if/else statement 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 The prefix string can be omitted if not required. chapter. Unlike in ordinary strings special characters do not have to be escaped setting the check_command attribute or custom variables as command parameters. objects using the object keyword: In general you need to write each statement on a new line. Updated by gbeutner on 2014-10-28 18:01:08 +00:00. Service type which uses the host_name attribute and the name are not permitted in object names. Meaning; i want to set several user so each user can see only one server or one host_group but … These Best practice is to manage constants in the constants.conf file. Keys must be unique and are 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 ). Updated by tgelf on 2016-09-09 09:13:51 +00:00, Should be implemented in the current master. @mwe: that's a different feature request, will also be implemented soon. In this example a has the value 7 after both instructions are executed. So here is how it can be done with another type of definition. 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' ], } … On 2016-09-09 09:13:59 +00:00 like numeric literals specific host group with the for loop keyword attribute for all of...
