Multiline error

Elastic Stack Beats

I have problem with filebeat multiline options.

/usr/bin/filebeat -version
filebeat version 5.5.1 (amd64), libbeat 5.5.1

Fragment of my server.log:

My filebeat config:

multiline:
      match: after
      negate: true
      pattern: ^[[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2}

This config don´t work.

I tested my config and log with this site https://play.golang.org/ and it works well.

package main

import (
	"fmt"
	"regexp"
	"strings"
)

var pattern = `^[[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2}`
var negate = true

var content = `10:25:14,694 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web]] (ajp-/172.16.15.61:8509-3)        servletPath=

  1. multiline settings are per prospector and not global level. From snippet you posted it seems like you didn't add the multiline settings into the correct section.

  2. You are recommend to quote regular expressions in yaml configurations. See: https://www.elastic.co/guide/en/beats/filebeat/current/regexp-support.html#regexp-support

Hi Steffens, today fix my error. I had to generate a grok pattern multiline.
MULTILINE (?s:.*).

Thanks!
