Logstash comes with two settings that simplify using modules with Elastic Cloud. The Elasticsearch and Kibana hostnames in Elastic Cloud may be hard to set in the Logstash config or on the commandline, so a Cloud ID can be used instead.
Cloud ID applies only when a Logstash module is enabled, otherwise
specifying Cloud ID has no effect. Cloud ID applies to data that gets sent via
the module, to runtime metrics sent via X-Pack monitoring, and to the endpoint
used by X-Pack central management features of Logstash, unless explicit
overrides to X-Pack settings are specified in
The Cloud ID, which can be found in the Elastic Cloud web console, is used by
Logstash to build the Elasticsearch and Kibana hosts settings.
It is a base64 encoded text value of about 120 characters made up of upper and
lower case letters and numbers.
If you have several Cloud IDs, you can add a label, which is ignored
internally, to help you tell them apart. To add a label you should prefix your
Cloud ID with a label and a
: separator in this format "<label>:<cloud-id>"
cloud.id will overwrite these settings:
This is optional. Construct this value by following this format "<username>:<password>". Use your Cloud username for the first part. Use your Cloud password for the second part, which is given once in the Cloud UI when you create a cluster. As your Cloud password is changeable, if you change it in the Cloud UI remember to change it here too.
cloud.auth when specified will overwrite these settings:
var.elasticsearch.username var.elasticsearch.password var.kibana.username var.kibana.password
These settings can be specified in the
logstash.yml settings file.
They should be added separately from any module configuration settings you may have added before.
# example with a label cloud.id: "staging:dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRub3RhcmVhbCRpZGVudGlmaWVy" cloud.auth: "elastic:YOUR_PASSWORD"
# example without a label cloud.id: "dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRub3RhcmVhbCRpZGVudGlmaWVy" cloud.auth: "elastic:YOUR_PASSWORD"
These settings can be also specified at the command line, like this:
bin/logstash --modules netflow -M "netflow.var.input.udp.port=3555" --cloud.id <cloud-id> --cloud.auth <cloud.auth>
