Hi,

I installed logstash on centos via rpm and installed via system-install as service.

When starting logstash I get the following warning:

```
**WARNING** You have enabled encryption but DISABLED certificate verification.
**WARNING** To make sure your data is secure change :ssl_certificate_verification to true

```

My output config looks like this:

```
output
{
  elasticsearch
  {
    #hosts => ["${ES_HOST}:${ES_PORT}"]
    hosts => ["${ES_HOSTS}"]
    ssl => "${USE_ES_SSL}"
    cacert => "${ES_CA_CERT_PATH}"
    ssl_certificate_verification => "${USE_ES_OUTPUT_SSL_CERT_VERIFICATION}"

    # credentials are fetched from envrionment or logstash-keystore

    user => "${LOGSTASH_USER}"
    password => "${LOGSTASH_PASSWORD}"

    index => "%{[@metadata][indexName]}"
  }
}

```

The Environment variable USE\_ES\_OUTPUT\_SSL\_CERT\_VERIFICATION is set via /etc/sysconfig/\<service\_name\>:

```
cat /etc/sysconfig/logstash-plx-0 | grep USE_ES_OUTPUT_SSL_CERT_VERIFICATION
USE_ES_OUTPUT_SSL_CERT_VERIFICATION=true

```

Using logstash 7.4.1

Any idea? Since I condigure cacert I would like to have the certificate checked.

Thanks, Andreas
