I'm importing some old apache logs through logstash to ES, and one step is converting the ip address to coordinates.
Originally I did not update the index template of logstash to use geo_point for the coordinates-field so I deleted the index and started the import from beginning.
The index now seems to properly recognise tieh coordinates-field as a geo_point when inspecting the mappings:
"coordinates": {
"type": "geo_point",
"ignore_malformed": false,
"ignore_z_value": true
},
However when I go over to Kibana / Maps / Create map / Add layer / Heat map, the dropdown does not list the logstash index. If I manually type logstash in the index pattern text box, I get " logstash doesn't match any options".
Why doesn't the heat map creation identify the index which has geo_point entries?
