|
|
==== Space-deliminated URIs in list-type params
|
|
|
|
List-type URI parameters will automatically expand strings that contain multiple
|
|
whitespace-delimited URIs into separate entries. This behaviour enables the expansion
|
|
of an arbitrary list of URIs from a single Environment- or Keystore-variable.
|
|
|
|
These plugins and options support this functionality:
|
|
|
|
* <<plugins-inputs-elasticsearch-hosts,Elasticsearch input plugin - `hosts`>>
|
|
* <<plugins-outputs-elasticsearch-hosts,Elasticsearch output plugin - `hosts`>>
|
|
* <<plugins-filters-elasticsearch-hosts,Elasticsearch filter plugin - `hosts`>>
|
|
|
|
You can use this functionality to define an environment variable with
|
|
multiple whitespace-delimited URIs and use it for the options above.
|
|
|
|
**Example**
|
|
|
|
```
|
|
ES_HOSTS="es1.example.com es2.example.com:9201 es3.example.com:9201"
|
|
```
