Shipper->Broker->Indexer->ES
1.input
input { stdin {} }
output {
stdout { codec=> rubydebug }
}
file {
codec => multiline {
pattern => "^\s"
what => "previous"
}
path => ["xx","xx"]
exclude => "1.log"
add_field => [ "log_ip", "xx" ]
tags => "tag1"
#设置新事件的标志
delimiter => "\n"
#设置多长时间扫描目录，发现新文件
discover_interval => 15
#设置多长时间检测文件是否修改
stat_interval => 1
#监听文件的起始位置，默认是end
start_position => beginning
#监听文件读取信息记录的位置
sincedb_path => "E:/software/logstash-1.5.4/logstash-1.5.4/test.txt"
#设置多长时间会写入读取的位置信息
sincedb_write_interval => 15
}
2.filter
filter {
multiline {
# 指定合并规则——所有不是以数字开头的行需要被合并
pattern => "^[^\d]"
# 合并到哪里——上一行
what => "previous"
}
filter {
multiline {
type => "type" #类型,不多说
pattern => "pattern, a regexp" #参数,也可以认为是字符,有点像grep ,如果符合什么字符就交给下面的 what 去处理
negate => boolean
what => "previous" or "next" #这个是符合上面 pattern 的要求后具体怎么处理,处理方法有两种,合并到上面一条日志或者下面的日志
}
}
filter {
grep {
match => [ "@message", "PHP Fatal error" ]
drop => false
add_tag => [fatal_error]
}
grep {
tags => [fatal_error]
match => [ "@message", ".*(xbox\.com|xbox\.mib\.com\.cn|supports\.game\.mib\.com\.cn)" ]
drop => false
add_tag => [xboxerror]
}
}
#过滤掉内容包含5.3.3与down以外日志
filter {

ruby {
code => "event.cancel"
}
}
}
#使用自带的过滤规则显示更多的字段
filter {
grok {
match => {"message" => "%{COMBINEDAPACHELOG}"}
}
}
#合并不是以[开头的日志
filter {
multiline {
pattern => "^[^[]"

3.output

#匹配内容包含paramiko与simplejson的日志通邮件发送
if [message] =~ /paramiko|simplejson/ {

替换
mutate {
type => "phplog"
gsub => [ "@message","'", "\"" ]
}
调试
