Logtash Grok Parse Error

Elastic Stack Logstash

Hi,

I want to parse CheckPoint Firewall syslog logs but logstash gives me an error.

Here is my error:

2019-05-09T15:12:18,565][ERROR][logstash.agent ] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, :exception=>"LogStash::ConfigurationError", :message=>"Expected one of #, => at line 65, column 13 (byte 1217) after filter {\nif [type] == "checkpoint" {\n grok {\n match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }\n\n dissect ", :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:2486:in map'", "/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:10:in compile_sources'", "org/logstash/execution/AbstractPipelineExt.java:149:in initialize'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:22:in initialize'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:90:in initialize'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline_action/create.rb:43:in block in execute'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:94:in block in exclusive'", "org/jruby/ext/thread/Mutex.java:148:in synchronize'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:94:in exclusive'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline_action/create.rb:39:in execute'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:327:in block in converge_state'"]}

Here is my CheckPoint syslog logs:

My filter:

filter {
  kv {
  }
  grok {
    match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}"           }

dissect { mapping => { "message" => "<%{level}>%{} %{ts} %{HostName} %{Device} %{DeviceID} - [%{kvString}" } }
date { match => [ "ts", "ISO8601" ] }
kv { source => "kvString" field_split => ";" value_split => ":" trim_key => " " }
  }
  mutate {
 gsub => ["timestamp"," "," "]
  }
  date {
     match => [ "timestamp", "ddMMMYYYY HH:mm:ss" ]
  }
}

how can i solve this issue?

My logstash version = 6.6.1
CheckPoint Version = R8020

Looks like you are missing a closing curly bracket for the grok block. If you indent properly this should be clearly visible.

4

we removed grok fields and just did with dissect

5

There is still a grok in the sample config.
