I recently downloaded LogStash 6.6.2, and I am currently working through the tutorial here.
I created a first-pipeline.conf file inside my Logstash directory:
input {
beats {
port => "5044"
}
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}"}
}
geoip {
source => "clientip"
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
}
}
When I run the command logstash -f first-pipeline.conf --config.reload.automatic, I see the following output:
Sending Logstash logs to C:/Users/M/Downloads/logstash-6.6.2/logs which is now configured via log4j2.properties

(For the purpose of the tutorial, ignoring the pipelines.yml file is acceptable -- or so it is claimed in the tutorial itself.)
What should I do to fix the mapper_parsing_exception?
