# Mandatory variables
Define the elastic repository version that will determine the version of filebeat:
```
elastic_major_version: "7.x"
```
Define the list of logstash endpoint where to send the logs:
Define the output for the logs, it can be either elasticsearch or logstash:
```
filebeat_output_elasticsearch_hosts:
  - host1
  - host2
```
or
```
filebeat_output_logstash_hosts:
  - host1
  - host2
```
If you use elasticsearch, the connection will use https and use the login/password of the server to authenticate itself.
You can change the protocol to http with:
```
filebeat_output_elasticsearch_protocol: "http"
```
# Optional variables
You can disable this filebeat role by setting this variable :
```yaml
filebeat_install: false
```

By default, filebeat will send the system logs to the index `logs-infra-system` and the other logs to `logs-{{ talas_project }}-{{ talas_group }}`.

Sometime, you want to send _all_ logs (even for the system), to the `logs-{{ talas_project }}-{{ talas_group }}` index.

If this is the case, you need to set this variable to false:
```
filebeat_separate_system_logs: false
```

You can define the loglevel of filebeat, the default is `warning`, possible values are error, warning, info, debug:
```
filebeat_logging_level: "warning"
```

You can add more module by creating this list:
```
