I have the longtitude and latitude in database ,and the type is float.
I want to use kibana to draw coordinate Map,
how can I get the right form with the data.
filter {
mutate {
add_field => {
"[location][lon]" => "%{RDC_lon}"
"[location][lat]" => "%{RDC_lat}"
}
}
#logstash mutate {
# convert => { "[location][lat]" => "float" }
# convert => { "[location][lon]" => "float" }
# }
#mutate {
# convert => {"location" => "geo_point"}
#}
}
in elasticsearch, the location is "%{RDC_lon}", how can I get the true value in "RDC_lon" which is a column in database
