# Icinga Template Library <a id="icinga-template-library"></a>

The Icinga Template Library (ITL) implements standard templates
and object definitions.

There is a subset of templates and object definitions available:

* [Generic ITL templates](10-icinga-template-library.md#itl-generic-templates)
* [CheckCommand definitions for Icinga 2](10-icinga-template-library.md#itl-check-commands) (this includes [icinga](10-icinga-template-library.md#itl-icinga),
[cluster](10-icinga-template-library.md#itl-icinga-cluster), [cluster-zone](10-icinga-template-library.md#itl-icinga-cluster-zone), [ido](10-icinga-template-library.md#itl-icinga-ido), etc.)
* [CheckCommand definitions for Monitoring Plugins](10-icinga-template-library.md#plugin-check-commands-monitoring-plugins)
* [CheckCommand definitions for Icinga 2 Windows Plugins](10-icinga-template-library.md#windows-plugins)
* [CheckCommand definitions for NSClient++](10-icinga-template-library.md#nscp-plugin-check-commands)
* [CheckCommand definitions for Manubulon SNMP](10-icinga-template-library.md#snmp-manubulon-plugin-check-commands)
* [Contributed CheckCommand definitions](10-icinga-template-library.md#plugin-contrib)

The ITL content is updated with new releases. Please do not modify
templates and/or objects as changes will be overridden without
further notice.

You are advised to create your own CheckCommand definitions in
`/etc/icinga2`.

## Windows Plugins for Icinga 2 <a id="windows-plugins"></a>

To allow a basic monitoring of Windows clients Icinga 2 comes with a set of Windows only plugins. While trying to mirror the functionalities of their linux cousins from the monitoring-plugins package, the differences between Windows and Linux are too big to be able use the same CheckCommands for both systems.

A check-commands-windows.conf comes with Icinga 2, it asumes that the Windows Plugins are installed in the PluginDir set in your constants.conf. To enable them the following include directive is needed in you icinga2.conf:

        include <windows-plugins>

One of the differences between the Windows plugins and their linux counterparts is that they consistently do not require thresholds to run, functioning like dummies without.


### Threshold syntax <a id="windows-plugins-thresholds"></a>

Threshold    | Meaning
:------------|:----------
"29"         | The threshold is 29.
"!29"        | The threshold is 29, but the negative of the result is returned.
"[10-40]"    | The threshold is a range from (including) 20 to 40, a value inside means the threshold has been exceeded.
"![10-40]"   | Same as above, but the result is inverted.

It can be enabled/disabled for example by setting them to "true" or "false", "1" or "0" would also work.  
Thresholds will always be "1".

> **Note**
>
> If they are enabled, performance data will be shown in the webinterface.

## Plugin Check Commands for NSClient++ <a id="nscp-plugin-check-commands"></a>

There are two methods available for querying NSClient++:

* Query the [HTTP API](10-icinga-template-library.md#nscp-check-api) locally or remotely (requires a running NSClient++ service)
* Run a [local CLI check](10-icinga-template-library.md#nscp-check-local) (does not require NSClient++ as a service)

Both methods have their advantages and disadvantages. One thing to
note: If you rely on performance counter delta calculations such as
CPU utilization, please use the HTTP API instead of the CLI sample call.

### nscp_api <a id="nscp-check-api"></a>

`check_nscp_api` is part of the Icinga 2 plugins. This plugin is available for
both, Windows and Linux/Unix.

Verify that the ITL CheckCommand is included in the [icinga2.conf](04-configuring-icinga-2.md#icinga2-conf) configuration file:

    vim /etc/icinga2/icinga2.conf

    include <plugins>

`check_nscp_api` runs queries against the NSClient++ API. Therefore NSClient++ needs to have
the `webserver` module enabled, configured and loaded.

You can install the webserver using the following CLI commands:

    ./nscp.exe web install
    ./nscp.exe web password — –set icinga

Now you can define specific [queries](https://docs.nsclient.org/reference/check/CheckHelpers.html#queries)
and integrate them into Icinga 2.

The check plugin `check_nscp_api` can be integrated with the `nscp_api` CheckCommand object:

`nscp_api_arguments` can be used to pass required thresholds to the executed check. The example below
checks the CPU utilization and specifies warning and critical thresholds.

```
check_nscp_api --host 10.0.10.148 --password icinga --query check_cpu --arguments show-all warning='load>40' critical='load>30'
check_cpu CRITICAL: critical(5m: 48%, 1m: 36%), 5s: 0% | 'total 5m'=48%;40;30 'total 1m'=36%;40;30 'total 5s'=0%;40;30
```


### nscp-local <a id="nscp-check-local"></a>

Icinga 2 can use the `nscp client` command to run arbitrary NSClient++ checks locally on the client.

You can enable these check commands by adding the following the include directive in your
[icinga2.conf](04-configuring-icinga-2.md#icinga2-conf) configuration file:

    include <nscp>

You can also optionally specify an alternative installation directory for NSClient++ by adding
the NscpPath constant in your [constants.conf](04-configuring-icinga-2.md#constants-conf) configuration
file:

    const NscpPath = "C:\\Program Files (x86)\\NSClient++"

By default Icinga 2 uses the Microsoft Installer API to determine where NSClient++ is installed. It should
not be necessary to manually set this constant.

Note that it is not necessary to run NSClient++ as a Windows service for these commands to work.

The check command object for NSClient++ is available as `nscp-local`.

## Plugin Check Commands for Manubulon SNMP <a id="snmp-manubulon-plugin-check-commands"></a>

The `SNMP Manubulon Plugin Check Commands` provide configuration for plugin check
commands provided by the [SNMP Manubulon project](http://nagios.manubulon.com/index_snmp.html).

**Note:** Some plugin parameters are only available in Debian packages or in a
[forked repository](https://github.com/dnsmichi/manubulon-snmp) with patches applied.

The SNMP manubulon plugin check commands assume that the global constant named `ManubulonPluginDir`
is set to the path where the Manubublon SNMP plugins are installed.

You can enable these plugin check commands by adding the following the include directive in your
[icinga2.conf](04-configuring-icinga-2.md#icinga2-conf) configuration file:

    include <manubulon>

contributed by community members.

These check commands assume that the global constant named `PluginContribDir`
is set to the path where the user installs custom plugins and can be enabled by
uncommenting the corresponding line in [icinga2.conf](04-configuring-icinga-2.md#icinga2-conf):

```
vim /etc/icinga2/icinga2.conf

include <plugin-contrib>
```

This is enabled by default since Icinga 2 2.5.0.

### Hardware <a id="plugin-contrib-hardware"></a>

This category includes all plugin check commands for various hardware checks.

#### hpasm <a id="plugin-contrib-command-hpasm"></a>

The [check_hpasm](https://labs.consol.de/de/nagios/check_hpasm/index.html) plugin
monitors the hardware health of HP Proliant Servers, provided that the `hpasm`
(HP Advanced Server Management) software is installed. It is also able to monitor
the system health of HP Bladesystems and storage systems.

The plugin can run in two different ways:

1. Local execution using the `hpasmcli` command line tool.
2. Remote SNMP query which invokes the HP Insight Tools on the remote node.

You can either set or omit `hpasm_hostname` custom attribute and select the corresponding node.

The `hpasm_remote` attribute enables the plugin to execute remote SNMP queries if set to `true`.
For compatibility reasons this attribute uses `true` as default value, and ensures that
specifying the `hpasm_hostname` always enables remote checks.

#### webinject <a id="plugin-contrib-command-webinject"></a>

The [check_webinject](https://labs.consol.de/de/nagios/check_webinject/index.html) plugin
uses [WebInject](http://www.webinject.org/manual.html) to test web applications
and web services in an automated fashion.
It can be used to test individual system components that have HTTP interfaces
(JSP, ASP, CGI, PHP, AJAX, Servlets, HTML Forms, XML/SOAP Web Services, REST, etc),
and can be used as a test harness to create a suite of HTTP level automated functional,
acceptance, and regression tests. A test harness allows you to run many test cases
and collect/report your results. WebInject offers real-time results
display and may also be used for monitoring system response times.

Custom attributes passed as [command parameters](03-monitoring-basics.md#command-passing-parameters):

Name                    | Description
------------------------|--------------
webinject_config_file   | **Optional.** There is a configuration file named 'config.xml' that is used to store configuration settings for your project. You can use this to specify which test case files to run and to set some constants and settings to be used by WebInject.
webinject_output        | **Optional.** This option is followed by a directory name or a prefix to prepended to the output files. This is used to specify the location for writing output files (http.log, results.html, and results.xml). If a directory name is supplied (use either an absolute or relative path and make sure to add the trailing slash), all output files are written to this directory. If the trailing slash is ommitted, it is assumed to a prefix and this will be prepended to the output files. You may also use a combination of a directory and prefix.
webinject_no_output     | **Optional.** Suppresses all output to STDOUT except the results summary.
webinject_timeout       | **Optional.** The value [given in seconds] will be compared to the global time elapsed to run all the tests. If the tests have all been successful, but have taken more time than the 'globaltimeout' value, a warning message is sent back to Icinga.
webinject_report_type   | **Optional.** This setting is used to enable output formatting that is compatible for use with specific external programs. The available values you can set this to are: nagios, mrtg, external and standard.
webinject_testcase_file | **Optional.** When you launch WebInject in console mode, you can optionally supply an argument for a testcase file to run. It will look for this file in the directory that webinject.pl resides in. If no filename is passed from the command line, it will look in config.xml for testcasefile declarations. If no files are specified, it will look for a default file named 'testcases.xml' in the current [webinject] directory. If none of these are found, the engine will stop and give you an error.
