# Prerequisites

Required:

- Have wget installed
- Have the apache server status module enabled

# Configuration

To install wget on centOS, we use the following command :

```
yum install wget
```

To check that it is installed we use:

```
rpm -qa | grep wget
```

We will also need to enable status in the apache configuration file, in centOS this is in :

```
cd /etc/httpd/conf
```

# Configuration in pandora

In the pandora terminal, once downloaded, we will move it to the /etc/pandora/plugins folder, which is where we place the agent plugins.

We will give permissions to the file with :

```
chmod 755 apache_plugin
```

Then we go to the pandora agent, located in /etc/pandora, open the conf and at the bottom we put :

```
module_plugin apache_plugin (apache_url_to_server_status)
```

In the enterprise version we will be able to do it by remote configuration.

Once this is done, we update the agent and the modules will be created:
