Hi,  
I'm trying to parse a log using the following config:

> input {  
> udp {  
> port =\> 5555  
> type =\> "esetlog"  
> add\_field =\> {  
> "etl\_input\_port" =\> 5555  
> "etl\_input\_protocol" =\> "udp"  
> }
> 
> }  
> }
> 
> filter {  
> if [type] == "esetlog" {  
> grok {  
> match =\> {  
> "message" =\> "\<%{NONNEGINT:syslog\_pri}\>%{NONNEGINT:version} %{TIMESTAMP\_ISO8601:syslog\_timestamp} (?\<server\_name\>._){"event\_type":"%{WORD:event\_type}","ipv4":"%{IPV4:device\_ip}","hostname":"(?._)","source\_uuid":"%{UUID:uuid}","occured":"(?\<date\_of\_event\>%{MONTHDAY}[/-]%{MONTH}[/-]%{YEAR} %{TIME})","severity":"%{WORD:severity}","(event":"(?._)|threat\_type":"(?\<threat\_type\>._))","(source\_address":"%{IPV4:source\_address}|threat\_name":"(?\<threat\_name\>._))","(source\_address\_type":"%{WORD:source\_address\_type}|scanner\_id":"(?\<scanner\_id\>._))","(source\_port":%{NUMBER:source\_port}|scan\_id":"(?\<scan\_id\>._))(,"|",")(target\_address":"%{IPV4:target\_address}|engine\_version":"(?\<engine\_version\>._))","(object\_type":"%{WORD:object\_type}|target\_address\_type":"%{WORD:target\_address\_type})","(object\_uri":"(?._)|target\_port":%{NUMBER:target\_port})(,"|",")(action\_taken":"(?\<action\_taken\>._)|protocol":"%{WORD:protocol})","(threat\_handled":%{WORD:threat\_handled}|account":"(?._))(,"|",")(need\_restart":%{WORD:need\_restart}|process\_name":"(?\<process\_name\>._))(,"|",")(username":"(?._)|inbound":%{WORD:inbound})(,"|",")(processname":"%{WINPATH:processname}|threat\_name":"(?\<threat\_name\>._))","(circumstances":"(?._).","|aggregate\_count":%{NUMBER:aggregate\_count})(hash":"(?._)")?(})%{GREEDYDATA:error}"  
> }  
> }  
> }  
> }

This is the error is receive:

`[ERROR][logstash.agent] Failed to execute action {:id=>:main, :action_type=>LogStash::ConvergeResult::FailedAction, :message=>"Expected one of [\\t\\r\\n], \"#\", \"{\", \"}\" at line 19, column 147 (byte 469) after filter {\n if [type] == \"esetlog\" {\n grok {\n match => {\n \"message\" => \"<%{NONNEGINT:syslog_pri}>%{NONNEGINT:version} %{TIMESTAMP_ISO8601:syslog_timestamp} (?<server_name>.*){\\\"event_type\"", :backtrace=>["/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:41:in `compile\_imperative'", "/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:49:in `compile_graph'", "/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:11:in `block in compile\_sources'", "org/jruby/RubyArray.java:2580:in `map'", "/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:10:in `compile\_sources'", "org/logstash/execution/AbstractPipelineExt.java:161:in `initialize'", "org/logstash/execution/JavaBasePipelineExt.java:47:in `initialize'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline\_action/reload.rb:37:in `execute'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:326:in `block in converge\_state'"]}`

Your data in the message field has `"` in it and it thinks the string is ending and then goes wacko.

Try wrapping the data in a `'` instead.

```auto
"message" => 'data goes here and can gave a " in it'

```

If that doesn't work then you just need to escape all of them `/`.
