Ansible CLI
Connector dependencies​
The following monitoring connectors will be installed when you install the Ansible CLI connector through the Configuration > Connectors > Monitoring Connectors menu:
Pack assets​
Templates​
The Ansible CLI monitoring connector doesn't have any host templates.
Discovery rules​
Host discovery​
| Rule name | Description |
|---|---|
| Ansible CLI | Discover hosts by requesting Ansible using CLI |
More information about discovering hosts automatically is available on the dedicated page.
Collected metrics & status​
No metrics or status for this monitoring connector.
Prerequisites​
To be able to execute this monitoring connector's host discovery, you should be able to execute the following CLI command:
ANSIBLE_LOAD_CALLBACK_PLUGINS=true ANSIBLE_STDOUT_CALLBACK=json ansible %(host_pattern) --module-name=setup
Installing the monitoring connector​
Pack​
The installation procedures for monitoring connectors are slightly different depending on whether your license is offline or online.
- If the platform uses an online license, you can skip the package installation instruction below as it is not required to have the connector displayed within the Configuration > Connectors > Monitoring Connectors menu. If the platform uses an offline license, install the package on the central server with the command corresponding to the operating system's package manager:
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11 & 12
- CentOS 7
dnf install centreon-pack-applications-ansible-cli
dnf install centreon-pack-applications-ansible-cli
apt install centreon-pack-applications-ansible-cli
yum install centreon-pack-applications-ansible-cli
- Whatever the license type (online or offline), install the Ansible CLI connector through the Configuration > Connectors > Monitoring Connectors menu.
Plugin​
Since Centreon 22.04, you can benefit from the 'Automatic plugin installation' feature. When this feature is enabled, you can skip the installation part below.
You still have to manually install the plugin on the poller(s) when:
- Automatic plugin installation is turned off
- You want to run a discovery job from a poller that doesn't monitor any resource of this kind yet
More information in the Installing the plugin section.
Use the commands below according to your operating system's package manager:
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11 & 12
- CentOS 7
dnf install centreon-plugin-Applications-Ansible-Cli
dnf install centreon-plugin-Applications-Ansible-Cli
apt install centreon-plugin-applications-ansible-cli
yum install centreon-plugin-Applications-Ansible-Cli
Troubleshooting​
Please find the troubleshooting documentation for Centreon Plugins typical issues.
Available modes​
In most cases, a mode corresponds to a service template. The mode appears in the execution command for the connector. In the Centreon interface, you don't need to specify a mode explicitly: its use is implied when you apply a service template. However, you will need to specify the correct mode for the template if you want to test the execution command for the connector in your terminal.
All available modes can be displayed by adding the --list-mode parameter to
the command:
/usr/lib/centreon/plugins/centreon_ansible_tower.pl \
--plugin=apps::automation::ansible::cli::plugin \
--list-mode
The plugin brings the following modes:
| Mode | Linked service template |
|---|---|
| discovery code | Used for host discovery |
Available options​
Generic options​
All generic options are listed here:
| Option | Description |
|---|---|
| --mode | Define the mode in which you want the plugin to be executed (see --list-mode). |
| --dyn-mode | Specify a mode with the module's path (advanced). |
| --list-mode | List all available modes. |
| --mode-version | Check minimal version of mode. If not, unknown error. |
| --version | Return the version of the plugin. |
| --custommode | When a plugin offers several ways (CLI, library, etc.) to get information the desired one must be defined with this option. |
| --list-custommode | List all available custom modes. |
| --multiple | Multiple custom mode objects. This may be required by some specific modes (advanced). |
| --pass-manager | Define the password manager you want to use. Supported managers are: environment, file, keepass, hashicorpvault and teampass. |
| --verbose | Display extended status information (long output). |
| --debug | Display debug messages. |
| --filter-perfdata | Filter perfdata that match the regexp. Example: adding --filter-perfdata='avg' will remove all metrics that do not contain 'avg' from performance data. |
| --filter-perfdata-adv | Filter perfdata based on a "if" condition using the following variables: label, value, unit, warning, critical, min, max. Variables must be written either %{variable} or %(variable). Example: adding --filter-perfdata-adv='not (%(value) == 0 and %(max) eq "")' will remove all metrics whose value equals 0 and that don't have a maximum value. |
| --explode-perfdata-max | Create a new metric for each metric that comes with a maximum limit. The new metric will be named identically with a '_max' suffix). Example: it will split 'used_prct'=26.93%;0:80;0:90;0;100 into 'used_prct'=26.93%;0:80;0:90;0;100 'used_prct_max'=100%;;;; |
| --change-perfdata --extend-perfdata | Change or extend perfdata. Syntax: --extend-perfdata=searchlabel,newlabel,target[,[newuom],[min],[max]] Common examples: =over 4 Convert storage free perfdata into used: --change-perfdata='free,used,invert()' Convert storage free perfdata into used: --change-perfdata='used,free,invert()' Scale traffic values automatically: --change-perfdata='traffic,,scale(auto)' Scale traffic values in Mbps: --change-perfdata='traffic_in,,scale(Mbps),mbps' Change traffic values in percent: --change-perfdata='traffic_in,,percent()' =back |
