我正在用tomcat安装logstash并且有问题抓住java堆栈跟踪调用，以下是我的配置
input {
udp {
type => "tomcat"
port => "514"
format => "plain"
}
}
filter{
multiline {
pattern => "(^.+Exception.*)|(^\s+at .+)|(^\s+... \d+ more)|(^\s*Caused by:.+)"
what => "previous"
}
}
这是tomcat的示例日志

我累了所有的组合，没有工作:(我不知道它是如何为其他人工作..
我试过跟随它也没有用
pattern => "^%{TIMESTAMP_ISO8601}"
negate => true
以下是结果

我在调试模式下使用udp协议运行logstash和一些奇怪的数字<139>进来@messages看到以下输出调试，如果我使用nc命令发送样本日志它的工作但不知何故与tomcat syslog它不工作

是否所有日志都以日期时间开头？
您可以将其用作模式。例如，
input {
stdin {
}
}
filter {
multiline {
pattern => "^%{TIMESTAMP_ISO8601} "
negate => true
what => previous
}
}
output {
stdout {debug => true}
}
这个过滤器在我的日志上工作。希望它可以帮助你:)
