Add layers for the Elasticsearch data
editAdd layers for the Elasticsearch data
editTo avoid overwhelming the user with too much data at once, you’ll add two layers for Elasticsearch data.
- The first layer will display individual documents. The layer will appear when the user zooms in the map to show smaller regions.
- The second layer will display aggregated data that represents many documents. The layer will appear when the user zooms out the map to show larger amounts of the globe.
Add a vector layer to display individual documents
editThis layer displays web log documents as points. The layer is only visible when users zoom in the map past zoom level 9.
- Click Add layer.
- Click the Documents layer.
- Set Index pattern to kibana_sample_data_logs.
- Click the Add layer button.

- Click Add under Tooltip fields.
- In the popover, select clientip, timestamp, host, request, response, machine.os, agent, and bytes and click Add.
- Set Fill color to #2200ff.

Click Save & close.
Your map now looks like this between zoom levels 9 and 24:
Add a vector layer to display aggregated data
editAggregations group Elasticsearch documents into grids. You can calculate metrics for each gridded cell.
You’ll create a layer for aggregated data and make it visible only when the map is zoomed out past zoom level 9. Darker colors will symbolize grids with more web log traffic, and lighter colors will symbolize grids with less traffic. Larger circles will symbolize grids with more total bytes transferred, and smaller circles will symbolize grids with less bytes transferred.
