While doing some sensor analytics demo in Kibana, we often felt the need to fill the indexes with a large amount of sensor data. Doing this via Logstash was a little bit cumbersome, so we integrated Elasticsearch connector into our Database generation tool.
Using our DBTool, you could simply create a template for sensor readings and then quickly populate the ES index with up to 100K documents, which are generated from that template. We believe this tool could be used for a variety of other use cases as well for ES community.
We are looking forward to feedback from community and ideas for improvement. Please signup at https://iotify.io/ and give it a try.
