Logstash无法从文件输入中读取 [英] Logstash not reading from file input
问题描述
我正在运行 ELK堆栈的此实现,这非常简单明了配置.
I'm running this implementation of the ELK stack, which is pretty straightforward and easy to configure.
我可以使用netcat将TCP输入推入堆栈,如下所示:
I can push TCP input through the stack using netcat like so:
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:
But I cannot get the Logstash to read the file paths I specify in the config:
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:
Here is the startup output from the stack regarding logstash input:
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.
There is no indication the pipeline has any issues starting.
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.
I've also checked that the log files have been updated since the display of TCP input, and they have. The last Logstash-specific log from the ELK stack comes from either startup or the TCP input.
以下是我整个Logstash启动日志记录,以帮助您解决问题:

推荐答案
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.
I found the issue - I needed to map the log files from the host into the container(Docker noob). The local paths I was specifying in the Logstash config were fine for TCP, but were unavailable inside the container without volume mapping.
首先,我在Dockerfile中为Logstash创建了容器的内部日志目录:
First, I created the container's internal log directories in the Dockerfile for Logstash:
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:
Then I volume-mapped my host's log directories into them in the docker-elk/docker-compose.yml file where Logstash is configured:
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:
Finally, I replaced the paths in logstash/pipelines/logstash.config with the directories created in the Dockerfile:
file {
path => [
"/usr/share/appOneLogs",
"/usr/share/appTwoLogs",
]
}
值得注意的是,我删除了 start_position =>从文件输入定义开始"
,因为这会将默认行为覆盖为
Also of note, I removed start_position => "beginning"
from the file input definition as this overrides the default behavior to treat files like live streams and thus start at the end.
