Hello,

I configured an input for receiving snmp traps. However non of them get stored in elasticsearch. When looking at the output of rubydebug errors showe up:

ailed action. {:status=\>400, :action=\>["index", {:\_id=\>nil, :\_index=\>"logstash-prtrap-2016.02.24", :\_type=\>"prtrap", :\_routing=\>nil}, #\<LogStash::Event:0x261fae28 @metadata\_accessors=#\<LogStash::Util::Accessors:0x692a5f5f @store={}, @lut={}\>, @cancelled=false, @data={"message"=\>"#\<SNMP::SNMPv2\_Trap:0x1fc329e6 @request\_id=658842679, @error\_index=0, @error\_status=0.....  
...  
:response=\>{"create"=\>{"\_index"=\>"logstash-prtrap-2016.02.24", "\_type"=\>"prtrap", "\_id"=\>"AVMSmlv7r0d0YpfXvMzQ", "status"=\>400, "error"=\>{"type"=\>"mapper\_parsing\_exception", "reason"=\>"Field name [RFC1065-SMI::enterprises.9.9.712.1.1.2.1.10.0] cannot contain '.'"}}}, :level=\>:warn}

logstash-2.2.0  
elasticsearch-2.2.0

Regards,

As of Elasticsearch 2.0, field names can't contain periods. Consider using the [de\_dot filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-de_dot.html).

Magnus, thank you. I was able to solve this by using the suggested filter.
