Logstash——multiline 插件，匹配多行日志
本文内容
- 测试数据
- 字段属性
- 按多行解析运行时日志
- 把多行日志解析到字段
- 参考资料
在处理日志时，除了访问日志外，还要处理运行时日志，该日志大都用程序写的，比如 log4j。运行时日志跟访问日志最大的不同是，运行时日志是多行，也就是说，连续的多行才能表达一个意思。
本文主要说明，如何用 multiline 出来运行日志。
如果能按多行处理，那么把他们拆分到字段就很容易了。

测试数据
[16-04-12 03:40:01 DEBUG] model.MappingNode:- ['/store/shopclass'] matched over.
[16-04-12 03:40:02 DEBUG] impl.JdbcEntityInserter:- from product_category product_category
where product_category.PARENT_ID is null and product_category.STATUS = ? and product_category.DEALER_ID is null
order by product_category.ORDERS asc
[16-04-12 03:40:03 DEBUG] model.MappingNode:- ['/store/shopclass'] matched over.
[16-04-12 03:40:04 DEBUG] model.MappingNode:- ['/store/shopclass'] matched over.
[16-04-12 03:40:05 DEBUG] impl.JdbcEntityInserter:- from product_category product_category
where product_category.PARENT_ID is null and product_category.STATUS = ? and product_category.DEALER_ID is null
order by product_category.ORDERS desc
[16-04-12 03:40:06 DEBUG] impl.JdbcEntityInserter:- from product_category product_category
where product_category.PARENT_ID is null and product_category.STATUS = ? and product_category.DEALER_ID is null
order by product_category.ORDERS asc
[16-04-12 03:40:07 DEBUG] model.MappingNode:- ['/store/shopclass'] matched over.
测试是在7秒内发生的（当然是假数据）。可以看到，第二、五、六秒的日志是多行的，有条SQL语句。其他是单行的。
字段属性
对 multiline 插件来说，有三个设置比较重要：negate、pattern 和 what。
negate
类型是 boolean
默认为
false否定正则表达式（如果没有匹配的话）。
pattern
必须设置
类型为 string
没有默认值
要匹配的正则表达式。
what
必须设置
可以为
previous 或next没有默认值
如果正则表达式匹配了，那么该事件是属于下一个或是前一个事件？
按多行解析运行时日志
示例1：若配置文件如下所示，
input {
file{
path=>"/usr/local/elk/logstash/logs/c.out"
type=>"runtimelog"
codec=> multiline {
pattern => "^\["
negate => true
what => "previous"
}
start_position=>"beginning"
sincedb_path=>"/usr/local/elk/logstash/sincedb-access"
ignore_older=>0
}
}
output{
stdout{
codec=>rubydebug
}
}
说明：匹配以“[”开头的行，如果不是，那肯定是属于前一行的。
解析结果如下所示，能解析出6个JSON：
{
"@timestamp" => "2016-06-01T04:37:43.147Z",

解析时，最后一行日志，不会解析。只有当再追加一条日志时，才会解析最后一条日志。
示例2：若将配置文件修改为，
input {
file{
path=>"/usr/local/elk/logstash/logs/c.out"
type=>"runtimelog"
codec=>multiline {
pattern => "^\["
negate => true
what => "next"
}

sincedb_path=>"/usr/local/elk/logstash/sincedb-access"
ignore_older=>0
}
}
output{
stdout{
codec=>rubydebug
}
}
解析结果为，能解析出7个JSON：

把多行日志解析到字段

codec=>multiline {

negate => true
what => "previous"
}

filter {
grok {

}
}
output{
stdout{
codec=>rubydebug
