Logstash error on new install

Elastic Stack Logstash
1

I installed logstash 7.13.2 and i'm getting a couple configuration errors that I cannot seem to find the cause.

</>
Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, :exception=>"LogStash::ConfigurationError"
, :message=>"Expected one of [ \t\r\n], "#", "input", "filter", "output" at line 3, column 1 (byte 38) after ", :backtrace=>["/usr/share/logstash/logstash-core/lib/logstash/comp

If I am reading these errors correct there is a missing character at line 3 in the compiler.rb config and/or java_pipeline.rb but I'm not seeing the error. I have included both files below.

</>
#compiler.rb

require 'logstash/compiler/lscl/lscl_grammar'

module LogStash; class Compiler
include ::LogStash::Util::Loggable

def self.compile_imperative(source_with_metadata, support_escapes)
if !source_with_metadata.is_a?(org.logstash.common.SourceWithMetadata)
raise ArgumentError, "Expected 'org.logstash.common.SourceWithMetadata', got #{source_with_metadata.class}"
end

grammar = LogStashCompilerLSCLGrammarParser.new
config = grammar.parse(source_with_metadata.text)

if config.nil?
raise ConfigurationError, grammar.failure_reason
end

config.process_escape_sequences = support_escapes
config.compile(source_with_metadata)
end
end; end

I am new to logstash so any recommendations or help is greatly appreciated!!

generally this error is in your config file.
post your config file if possible

3

I feel sheepish in asking this question. Which config file?

4

where is this error from? is it when you try to start logstash?

5

This backtrace is telling you that the compiler raised an exception at this line of code

raise ConfigurationError, grammar.failure_reason

The grammar.failure_reason

is telling you that there is a problem at line 3 of your configuration. You will have told logstash where to find this with one of

  • -e to specify a config string on the command line
  • -f to specify a filename on the command line
  • path.config in logstash.yml
  • path.config in pipelines.yml
  • config.string in pipelines.yml
