Hi i try monitoring logstash for detect why i have delay on the logs ingest.
But when i try put multiple hosts in the property `xpack.monitoring.elasticsearch.hosts` this fails .
The value is injected with the enviroment variable ELASTIC\_SERVER
This is an example
```auto
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: ${ELASTIC_USER}
xpack.monitoring.elasticsearch.password: ${ELASTIC_PASS}
xpack.monitoring.elasticsearch.hosts: ['${ELASTIC_SERVER}']
```
And the environment variable have this value
`https://host1:9200,https://host2:9200`
Logstash show this error:
`[2021-11-17T17:32:01,398][ERROR][logstash.licensechecker.licensereader] Unable to retrieve license information from license server {:message=>"URI is not valid - host is not specified"}`
I try different values for the environment variable and logstash.yml but i have same error, only works with one host, if i put more than one, fails.
Examples of values and logstash.yml
```auto
'https://host1:9200,https://host2:9200'
'https://host1:9200','https://host2:9200'
"https://host1:9200,https://host2:9200"
"https://host1:9200","https://host2:9200"
```
```auto
xpack.monitoring.elasticsearch.hosts: ['${ELASTIC_SERVER}']
xpack.monitoring.elasticsearch.hosts: [${ELASTIC_SERVER}]
xpack.monitoring.elasticsearch.hosts: ["${ELASTIC_SERVER}"]
xpack.monitoring.elasticsearch.hosts: '${ELASTIC_SERVER}'
xpack.monitoring.elasticsearch.hosts: '${ELASTIC_SERVER}'
xpack.monitoring.elasticsearch.hosts: ${ELASTIC_SERVER}
```
Actually my conf is:
```auto
https://host1:9200
xpack.monitoring.elasticsearch.hosts: ['${ELASTIC_SERVER}']
```
NOTE: Logstash **7.14.1** run as a pod inside openshift, is a custom image and for now i no have intention to add metricbeat inside to this image.
_Dockerfile fragment_
```auto
ADD logstash-${version}.tar.gz /opt/
ADD root /
ADD offline-plugins /opt/logstash-${version}/offline-plugins
COPY logstash.conf /opt/logstash-${version}/conf/logstash.conf
COPY run /opt/logstash-${version}/
COPY install_plugin /opt/logstash-${version}/
COPY logstash.yml /opt/logstash-${version}/config/
```

That is what I would expect. Related answer [here](https://discuss.elastic.co/t/filter-elements-based-on-array-constant-or-array-environment-variable/269074/2).

logstash.conf works,
logstash.yml no, it's for monitoring logstash.
