Я очень новичок в ELK, я установил ELK версии 5.6.12 на CentOS-сервер. Elasticsearch и Kibana отлично работает. Но я не могу подключить Logstash к Elastic search.
Я установил переменную среды как
export JAVA_HOME=/usr/local/jdk1.8.0_131
export PATH=/usr/local/jdk1.8.0_131/bin:$PATH
Я запускаю простой тест:
bin/logstash -e 'input { stdin { } } output { elasticsearch { host => localhost:9200 protocol => "http" port => "9200" } }'
Я получаю ошибку:
WARNING: Could not find logstash.yml which is typically located in
$LS_HOME/config or /etc/logstash. You can specify the path using --
path.settings. Continuing using the defaults
Could not find log4j2 configuration at path
/etc/logstash/logstash.yml/log4j2.properties. Using default config which
logs errors to the console
Простой «слеш», упомянутый в официальной документации Logstash, работает следующим образом:
$bin/logstash -e 'input { stdin { } } output { stdout {} }'

The stdin plugin is now waiting for input: {
"@version" => "1",
"host" => "localhost",
"@timestamp" => 2018-11-01T04:44:58.648Z,
"message" => "Hello" }
В чем может быть проблема?
