Я использую эту реализацию стека ELK, которая довольно проста и проста в настройке.
Я могу протолкнуть ввод TCP через стек, используя netcat, например:
nc localhost 5000 < /Users/me/path/to/logs/appOne.log
nc localhost 5000 < /Users/me/path/to/logs/appOneStackTrace.log
nc localhost 5000 < /Users/me/path/to/logs/appTwo.log
nc localhost 5000 < /Users/me/path/to/logs/appTwoStackTrace.log
Но я не могу заставить Logstash прочитать пути к файлам, которые я указал в конфигурации:
input {
tcp {
port => 5000
}
file {
path => [
"/Users/me/path/to/logs/appOne.log",
"/Users/me/path/to/logs/appOneStackTrace.log",
"/Users/me/path/to/logs/appTwo.log",
"/Users/me/path/to/logs/appTwoStackTrace.log"
]
type => "log"
start_position => "beginning"
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
}
}
Вот вывод при запуске из стека относительно ввода logstash:
logstash_1 | [2019-01-28T17:44:33,206][INFO ][logstash.inputs.tcp ] Starting tcp input listener {:address=>"0.0.0.0:5000", :ssl_enable=>"false"}
logstash_1 | [2019-01-28T17:44:34,037][INFO ][logstash.inputs.file ] No sincedb_path set, generating one based on the "path" setting {:sincedb_path=>"/usr/share/logstash/data/plugins/inputs/file/.sincedb_a1605b28f1bc77daf785a8805c32f578", :path=>["/Users/me/path/to/logs/appOne.log", "/Users/me/path/to/logs/appOneStackTrace.log", "/Users/me/path/to/logs/appTwo.log", "/Users/me/path/to/logs/appTwoStackTrace.log"]}
Нет никаких признаков того, что у конвейера есть какие-либо проблемы с запуском.
Я также проверил, что файлы журнала были обновлены с момента отображения ввода TCP, и они имеют.Последний журнал, специфичный для Logstash, из стека ELK поступает либо из автозагрузки, либо со входа TCP.
Вот вся моя запись в журнал запуска Logstash на случай, если это будет полезно:
