Hi,
In logstash 5, when we had a "Could not index event to Elasticsearch", logstash logged the event with the message that caused the exception.
Ex:
[2019-04-08T14:47:58,939][WARN][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=\>400, :action=\>["index", {:\_id=\>nil, :\_index=\>"indexZZZ", :\_type=\>"typeL", :\_routing=\>nil}, 2019-04-08T14:47:52.100Z SERVERX {"EventSeverity":"Verbose" ....}], :response=\>{"index"=\>{"\_index"=\>"indexZZZ", "\_type"=\>"typeL", "\_id"=\>"sdfsdfsdfsdf", "status"=\>400, "error"=\>{"type"=\>"illegal\_argument\_exception", "reason"=\>"mapper [field] of different type, current\_type [long], merged\_type [text]"}}}}
The messaged tried to insert in elasticsearch was "2019-04-08T14:47:52.100Z SERVERX {"EventSeverity":"Verbose" ....}"
In logstash 6, the same errors are logging in the following way:
Could not index event to Elasticsearch. {:status=\>400, :action=\>["index", {:\_id=\>nil, :\_index=\>"indexAAA", :\_type=\>"doc", :routing=\>nil}, #LogStash::Event:0x70f59e7f], :response=\>{"index"=\>{"\_index"=\>"indexAAA", "\_type"=\>"doc", "\_id"=\>"tmBE\_WkBDnuvom78Msig", "status"=\>400, "error"=\>{"type"=\>"mapper\_parsing\_exception", "reason"=\>"failed to parse [field]", "caused\_by"=\>{"type"=\>"illegal\_argument\_exception", "reason"=\>"For input string: "aaaaaaa""}}}}}
The log message cannot be retrieve from the log, it's "#LogStash::Event:0x70f59e7f". is it possible to force logstash to log the message? How?
Best Regards,
Filipe Ferreira.
