Why the host mapping is not wokring

Hi Team,

Need clarification on why this mapping is not working.
Logstash field,
"host" => "vzon-pdm-prod.gnm.dns.denc.nka.net"

Template mapping:
"host": {"type": "keyword" }

Its throwing below error while sending mapping to Elastic,

Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"lsh-usa_verizon_core2a_8650sdm_v4-2019.11.23", :_type=>"_doc", :_routing=>nil}, #LogStash::Event:0x7986175f], :response=>{"index"=>{"_index"=>"lsh-usa_verizon_core2a_8650sdm_v4-2019.11.23", "_type"=>"_doc", "_id"=>"B7aMlm4BIqQPqzL49rWu", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to find type parsed [string] for [host]"}}}}

If you use

output { stdout { codec => rubydebug } }

what do the [host] and [logtime] fields look like?

Hi Badger,

"host" => "vzon-pdm-prod.gnm.dns.denc.nka.net)"
I got rid of the host issue, am able to send host to the elastic.

However date mapping is giving me trouble,

logtime from grok stdout debug:

"logtime" => "2019-11-20 17:31:46"

Grok mapping:

Date parsing:
match => [ "logtime" ,"yyyy-MM-dd HH-mm-ss"]
timezone => UTC
target => "logtime"
Template mapping:
"logtime": {"type": "date", "format" : "yyyy-MM-dd HH-mm-ss"}

Error while sending to elastic:

A quick help reply on this will be great help for me please :slight_smile:

You have used a date filter to convert [logtime] to a LogStash::Timestamp. I don't think you need a template for the field once you have done that. elasticsearch will by default convert it to a date.
