   - use-node-label - If false local node cache will get nodelabel for nodeid. If true will use remote nodelabel (default: false)
   
   If you are uploading events from the local machine on which you are running this command, you should use
  
positive.code: The _mandatory_ parameters are
  
  - limit  - Limit of number of events to send 
          
  - offset - Offset for starting list of events

  | Parameter                 | Default               | Description
  |`elasticsearchUrl`         | http://localhost:9200 | URL of _Elasticsearch_ ReST interface
  |`esusername`               |                       | Username to access _Elasticsearch_
  |`espassword`               |                       | Username to access _Elasticsearch_
  |`logEventDescription`      | true                  | Whether to forward the event description field to _Elasticsearch_. It can be disabled because it contains a long text field that can be redundant with the rest of the metadata included in the event.
  |`archiveRawEvents`         | true                  | Archive events.
  |`archiveAlarms`            | true                  | Archive alarms.
  |`archiveAlarmChangeEvents` | true                  | Archive alarm change events.
  |`archiveOldAlarmValues`    | true                  | For alarm change events, we can choose to archive the detailed alarm values but this is expensive. Set false in production.
  |`archiveNewAlarmValues`    | true                  | 
  |`logAllEvents`             | false                 | If changed to true, then archive all events even if they have not been persisted in the OpenNMS database.
  |`batchSize`                | 1                     | Increase this value to enable batch inserts into Elasticsearch. This is the maximum size of a batch of events that is sent to Elasticsearch in a single connection.
  |`batchInterval`            | 0                     | This value specifies the maximum time interval between batch events (recommended: 500ms).

  Once you are sure everything is correctly configured, you can activate the _Elasticsearch_ forwarder by logging into the _OSGi_ console and installing the feature.
