Hi I am sending information from Logstash to Elasticsearch. The Elasticsearch is working fine but when I try to send it information to it from a log file it created the index for it but does not receive any of the information not sure why, help would be greatly appreciated.

this is the error I receive

[2017-11-06T14:09:16,033][WARN][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=\>400, :action=\>["index", {:\_id=\>nil, :\_index=\>"testing1234", :\_type=\>"OldLog", :\_routing=\>nil}, 2017-11-06T20:09:15.729Z xlrd23 10.04.14 20:07:02.53 (5211) FM 5037 [17 Oct 03], Bfed:23, what: 0, fdfdf: 0], :response=\>{"create"=\>{"\_index"=\>"testing1234", "\_type"=\>"OldLog", "\_id"=\>"AV-S840O3TjZGp2ACWuq", "status"=\>400, "error"=\>{"type"=\>"mapper\_parsing\_exception", "reason"=\>"failed to parse", "caused\_by"=\>{"type"=\>"illegal\_state\_exception", "reason"=\>"Mixing up field types: class org.elasticsearch.index.mapper.core.LongFieldMapper$LongFieldType != class org.elasticsearch.index.mapper.ip.IpFieldMapper$IpFieldType on field host"}}}}}

Looks like you have a conflict, where the `host` field is a long but you want to change it to an IP somewhere.

What is the current mapping of that field in the index?

Hey Warkolm thank you for replying.  
Im not sure what you mean by what is the mapping in the index sorry I am new to the ELK stalk.  
but for the host field it appears as the following in stdout.

"host" =\> "xlrd23 "

that is our server host name of where I have logstash installed

FYI we’ve renamed ELK to the Elastic Stack, otherwise Beats and APM feel left out! 😉

Run this - `curl -XGET ESHOSTIP:9200/testing1234/_mapping` and then paste the output. Please use the `</>` button to format it in the post as well 🙂

Ok, so you have this already defined in the mapping;

> [@magdieldominguez](#):
>
> "host" : {  
> "type" : "ip"  
> },

But the output is a string;

> [@magdieldominguez](#):
>
> "host" =\> "xlrd23 "

Hence the error.

To fix this you need to delete the index, update the mapping so that field is a `keyword` and then run Logstash again.

I have been beating myself trying to solve this for almost a week now thank you so much Warkolm! sucks but I cannot update the mappings the elasticsearch instance is administered by another group within our organization but all I did was remove the host field in my Logstash config file. Using the following

filter {  
mutate { remove\_field =\> ["host"] }  
}

but without your help I would have never figured out that that was the problem. Thank you for all your help!
