我使用带有bunyan的koajs将错误日志保存到我的服务器然后我使用filebeat将它们发送到我的logstash应用程序。
我的错误日志正在正确转发,但我现在想创建一个过滤器,它会在特定日志中添加标记。
{"name":"myapp","hostname":"sensu-node-dev","pid":227,"level":50,"err":{"message":"Cannot find module 'lol'","name":"Error","stack":"Error: Cannot find module 'lol'\n at Function.Module._resolveFilename (module.js:339:15)\n at Function.Module._load (module.js:290:25)\n at Module.require (module.js:367:17)\n at require (internal/module.js:16:19)\n at Object.<anonymous> (/srv/www/dev.site/app.js:27:6)\n at next (native)\n at Object.<anonymous> (/srv/www/dev.site/node_modules/koa-compose/index.js:29:5)\n at next (native)\n at onFulfilled (/srv/www/dev.site/node_modules/co/index.js:65:19)\n at /srv/www/dev.site/node_modules/co/index.js:54:5","code":"MODULE_NOT_FOUND"},"msg":"Cannot find module 'lol'","time":"2016-02-24T22:04:26.492Z","v":0}
现在,特定日志中有趣的部分是"err":{...}
和"name":"Error"
位。为简单起见,我只想创建一个过滤器,在日志中检测"name":"Error"
(如果存在),然后将标记add_tag => ["error"]
应用于日志。
这是我的/etc/logstash/conf.d/logstash.conf
文件:
input {
beats {
port => 5044
type => "logs"
}
}
filter {
grok {
type => "log"
pattern => "???" // <--- have no idea what to do here
add_tag => ["error"]
}
}
output {
elasticsearch {
hosts => "localhost:9200"
sniffing => true
manage_template => false
index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[@metadata][type]}"
}
http {
http_method => "post"
url => "<MY_URL>"
format => "message"
message => "{"text":"dis is workinz, you has error"}"
tags => ["error"]
}
}
我尝试了以下内容:
pattern => ""name":"Error""
但是出现了以下错误:
Error: Expected one of #, {, } at line 9, column 31 (byte 107) after filter {
grok {
match => { "message" => ""
You may be interested in the '--configtest' flag which you can
use to validate logstash's configuration before you choose
to restart a running system.
在任何地方都没有这种特定匹配类型的简单示例。
奖励:另外如何在logstash中逃脱,我无法找到关于这个主题的任何内容?
答案 0 :(得分:0)
如果您只想查看邮件中是否存在字符串,请尝试以下操作:
if [message] =~ /"name":"Error"/ {
mutate {
add_tag { ... }
}
}
如果你真的想将输入信息输入到字段中,请查看json编解码器或过滤器。
