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
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
'https://host1:9200,https://host2:9200'
'https://host1:9200','https://host2:9200'
"https://host1:9200,https://host2:9200"
"https://host1:9200","https://host2:9200"
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: ${ELASTIC_SERVER}
Actually my conf is:
https://host1:9200
xpack.monitoring.elasticsearch.hosts: ['${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.
