## <a id="cli-commands"></a> Icinga 2 CLI Commands
Icinga 2 ships its own integrated CLI commands supporting bash-autocompletion.
These CLI commands will allow you to use certain functionality
provided by and around the Icinga 2 daemon.
Each CLI command provides its own help and usage information, so please
make sure to always run them with the `--help` parameter.
Run `icinga2` without any arguments to get a list of all available global
options.

### <a id="cli-commands-autocompletion"></a> Icinga 2 CLI Bash Autocompletion
Bash Auto-Completion (pressing `<TAB>`) is provided only for the corresponding context.
While `--config` will suggest and auto-complete files and directories on disk,
`feature enable` will only suggest disabled features. `repository` will know
about object specific attributes, and so on. Try it yourself.
RPM and Debian packages install the bash completion files into
`/etc/bash_completion.d/icinga2`.
You will need to install the `bash-completion` package if not already installed.
RHEL/CentOS/Fedora:
# yum install bash-completion
SUSE:
# zypper install bash-completion
Debian/Ubuntu:
# apt-get install bash-completion
### <a id="cli-commands-global-options"></a> Icinga 2 CLI Global Options
#### Libraries
Instead of loading libraries using the [`library` config directive](13-language-reference.md#library)
you can also use the `--library` command-line option.
#### Constants
[Global constants](13-language-reference.md#constants) can be set using the `--define` command-line option.
#### <a id="config-include-path"></a> Config Include Path
When including files you can specify that the include search path should be
checked. You can do this by putting your configuration file name in angle
brackets like this:
include <test.conf>
This would cause Icinga 2 to search its include path for the configuration file
`test.conf`. By default the installation path for the Icinga Template Library
is the only search directory.
Using the `--include` command-line option additional search directories can be
added.
### <a id="cli-command-daemon"></a> CLI command: Daemon
The CLI command `daemon` provides the functionality to start/stop Icinga 2.
Furthermore it provides the [configuration validation](6-cli-commands.md#config-validation).
# icinga2 daemon --help
icinga2 - The Icinga 2 network monitoring daemon (version: v2.1.1-299-gf695275)
Usage:
icinga2 daemon [<arguments>]
Starts Icinga 2.
Global options:
-h [ --help ] show this help message
-V [ --version ] show version information
--color use VT100 color codes even when stdout is not a
terminal
-D [ --define ] arg define a constant
-l [ --library ] arg load a library
-I [ --include ] arg add include search directory
-x [ --log-level ] arg specify the log level for the console log
Command options:
-c [ --config ] arg parse a configuration file
-z [ --no-config ] start without a configuration file
-C [ --validate ] exit after validating the configuration
-e [ --errorlog ] arg log fatal errors to the specified log file (only works
in combination with --daemonize)
-d [ --daemonize ] detach from the controlling terminal
Report bugs at <https://dev.icinga.org/>
Icinga home page: <https://www.icinga.org/>
#### Config Files
Using the `--config` option you can specify one or more configuration files.
Config files are processed in the order they're specified on the command-line.
When no configuration file is specified and the `--no-config` is not used
Icinga 2 automatically falls back to using the configuration file
`SysconfDir + "/icinga2/icinga2.conf"` (where SysconfDir is usually `/etc`).
#### Config Validation
The `--validate` option can be used to check if your configuration files
contain errors. If any errors are found the exit status is 1, otherwise 0
is returned. More details in the [configuration validation](6-cli-commands.md#config-validation) chapter.
### <a id="cli-command-feature"></a> CLI command: Feature
The CLI commands for `enable` and `disable` feature support bash auto-completion
and will only suggest features for the corresponding context. Like disabling a
feature will only bring up all enabled features.
# icinga2 feature disable <tab>

### <a id="cli-command-object"></a> CLI command: Object
The `object` CLI command can be used to list all configuration objects and their
attributes. The command also shows where each of the attributes was modified.
That way you can also identify which objects have been created from your [apply rules](13-language-reference.md#apply).
More information can be found in the [troubleshooting](10-troubleshooting.md#list-configuration-objects) section.

## <a id="features"></a> Enabling/Disabling Features
Icinga 2 provides configuration files for some commonly used features. These
are installed in the `/etc/icinga2/features-available` directory and can be
enabled and disabled using the `icinga2 feature enable` and `icinga2 feature disable`
[CLI commands](6-cli-commands.md#cli-command-feature), respectively.
The `icinga2 feature enable` CLI command creates symlinks in the
`/etc/icinga2/features-enabled` directory which is included by default
in the example configuration file.
You can view a list of enabled and disabled features:
# icinga2 feature list
Disabled features: api command compatlog debuglog graphite icingastatus ido-mysql ido-pgsql livestatus notification perfdata statusdata syslog
Enabled features: checker mainlog notification
Using the `icinga2 feature enable` command you can enable features:
# icinga2 feature enable graphite
Enabling feature graphite. Make sure to restart Icinga 2 for these changes to take effect.
You can disable features using the `icinga2 feature disable` command:
# icinga2 feature disable ido-mysql livestatus
Disabling feature ido-mysql. Make sure to restart Icinga 2 for these changes to take effect.
Disabling feature livestatus. Make sure to restart Icinga 2 for these changes to take effect.
The `icinga2 feature enable` and `icinga2 feature disable` commands do not
restart Icinga 2. You will need to restart Icinga 2 using the init script
after enabling or disabling features.
## <a id="config-validation"></a> Configuration Validation
Once you've edited the configuration files make sure to tell Icinga 2 to validate
the configuration changes. Icinga 2 will log any configuration error including
a hint on the file, the line number and the affected configuration line itself.
The following example creates an apply rule without any `assign` condition.
apply Service "5872-ping4" {
import "generic-service"
check_command = "ping4"
//assign where match("5872-*", host.name)
}
Validate the configuration with the init script option `checkconfig`:
# /etc/init.d/icinga2 checkconfig
> **Note**
>
> Using [systemd](2-getting-started.md#systemd-service) you need to manually validate the configuration using
> the CLI command below.
Or manually passing the `-C` argument:
# /usr/sbin/icinga2 daemon -c /etc/icinga2/icinga2.conf -C
[2014-05-22 17:07:25 +0200] critical/ConfigItem: Location:
/etc/icinga2/conf.d/tests/5872.conf(5): }
/etc/icinga2/conf.d/tests/5872.conf(6):
/etc/icinga2/conf.d/tests/5872.conf(7): apply Service "5872-ping4" {
^^^^^^^^^^^^^
/etc/icinga2/conf.d/tests/5872.conf(8): import "test-generic-service"
/etc/icinga2/conf.d/tests/5872.conf(9): check_command = "ping4"
Config error: 'apply' is missing 'assign'
[2014-05-22 17:07:25 +0200] critical/ConfigItem: 1 errors, 0 warnings.
Icinga 2 detected configuration errors.
> **Tip**
>
> Icinga 2 will automatically detect the default path for `icinga2.conf`
> in `SysconfDir + /icinga2/icinga2.conf` and you can safely omit this parameter.
>
> `# icinga2 daemon -C`
If you encouter errors during configuration validation, please make sure
to read the [troubleshooting](10-troubleshooting.md#troubleshooting) chapter.
You can also use the [CLI command](6-cli-commands.md#cli-command-object) `icinga2 object list`
after validation passes to analyze object attributes, inheritance or created
objects by apply rules.
Find more on troubleshooting with `object list` in [this chapter](10-troubleshooting.md#list-configuration-objects).
Example filtered by `Service` objects with the name `ping*`:
# icinga2 object list --type Service --name *ping*
Object 'nbmif.int.netways.de!ping4' of type 'Service':
* __name = 'nbmif.int.netways.de!ping4'
* check_command = 'ping4'
% = modified in '/etc/icinga2/conf.d/services.conf', lines 17:3-17:25
* check_interval = 60
% = modified in '/etc/icinga2/conf.d/templates.conf', lines 28:3-28:21
* host_name = 'nbmif.int.netways.de'
% = modified in '/etc/icinga2/conf.d/services.conf', lines 14:1-14:21
* max_check_attempts = 3
% = modified in '/etc/icinga2/conf.d/templates.conf', lines 27:3-27:24
* name = 'ping4'
% = modified in '/etc/icinga2/conf.d/services.conf', lines 14:1-14:21
* retry_interval = 30
% = modified in '/etc/icinga2/conf.d/templates.conf', lines 29:3-29:22
* templates = [ 'ping4', 'generic-service' ]
% += modified in '/etc/icinga2/conf.d/services.conf', lines 14:1-14:21
% += modified in '/etc/icinga2/conf.d/templates.conf', lines 26:1-30:1
* type = 'Service'
* vars
% += modified in '/etc/icinga2/conf.d/services.conf', lines 18:3-18:19
* sla = '24x7'
% = modified in '/etc/icinga2/conf.d/services.conf', lines 18:3-18:19
## <a id="config-change-reload"></a> Reload on Configuration Changes
Everytime you have changed your configuration you should first tell Icinga 2
to [validate](6-cli-commands.md#config-validation). If there are no validation errors you can
safely reload the Icinga 2 daemon.
# /etc/init.d/icinga2 reload
> **Note**
>
> The `reload` action will send the `SIGHUP` signal to the Icinga 2 daemon
> which will validate the configuration in a separate process and not stop
> the other events like check execution, notifications, etc.
>
> Details can be found [here](12-migrating-from-icinga-1x.md#differences-1x-2-real-reload).
