Hello All,
I'm a n00b, and I'm having trouble changing a field's datatype in
elasticsearch - so that kibana can use it.
I read in a CSV with logstash. Here is a sample of that CSV:
DateTime,Session,Event,Data/Duration
2014-05-12T21:51:44,1399945863,Pressure,7.00
Here is my logstash config:
input {
file {
path =>
"/elk/Samples/CPAP_07_14_2014/CSV/SleepSheep_07_14_2014_no_header.csv"
start_position => beginning
}
}
filter {
csv {
columns => ["DateTime","Session","Event","Data/Duration"]
}
}
output {
elasticsearch {
host => localhost
}
stdout { codec => rubydebug }
}
Whenever the data reaches elasticsearch, the mapping shows the
"Date/Duration" field as a string, not a float, preventing kibana from
using it for graphing. I tried to use PUT on elasticsearch to overwrite
the mapping, but it wont let me.
Where should I configure this datatype? In the CSV filter, in the output,
in elasticsearch?
Thanks,
Barry
