我正在运行this的ELK堆栈实现，该实现非常简单且易于配置。
我可以使用netcat将TCP输入推入堆栈，如下所示：
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
但是我无法获取Logstash来读取我在配置中指定的文件路径：
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"
}
}
这是堆栈中有关logstash输入的启动输出：
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"]}
没有迹象表明管道开始出现任何问题。
我还检查了自显示TCP输入以来日志文件是否已更新，并且已经更新。 ELK堆栈中最后一个特定于Logstash的日志来自启动或TCP输入。
以下是我整个Logstash启动日志记录，以帮助您：

我发现了问题-我需要将日志文件从主机映射到容器（Docker noob）。我在Logstash配置中指定的本地路径对于TCP来说很好，但是在没有卷映射的容器中内部不可用。
首先，我在Dockerfile中为Logstash创建了容器的内部日志目录：
RUN mkdir /usr/share/appOneLogs
RUN mkdir /usr/share/appTwoLogs
然后我将配置了Logstash的docker-elk / docker-compose.yml文件中的主机日志目录卷映射到其中：
logstash:
build:
context: logstash/
args:
ELK_VERSION: $ELK_VERSION
volumes:
- ./logstash/config/logstash.yml:/usr/share/logstash/config/logstash.yml:ro
- ./logstash/pipeline:/usr/share/logstash/pipeline:ro
- /Users/me/path/to/appOne/logs:/usr/share/appOneLogs # this bit
- /Users/me/path/to/appTwo/logs:/usr/share/appTwoLogs # and this bit
ports:
- "5000:5000"
...
最后，我用在Dockerfile中创建的目录替换了logstash / pipelines / logstash.config中的路径：
file {
path => [
"/usr/share/appOneLogs",
"/usr/share/appTwoLogs",
]
}
还要注意，我从文件输入定义中删除了start_position => "beginning"，因为它覆盖了treat files like live streams and thus start at the end的默认行为。
