Hello, I am hoping someone might be able to provide some assistance with a Filebeat multiline issue I can't seem to resolve.
One server is running Novell Storage Services Auditing Client Logger (VLOG). Filebeat is installed on that same server configured to monitor the log file that's generated by VLOG. Each VLOG log entry is multiline (see example below) but can't seem to get Filebeat's multiline config to treat each entry as one. Instead it treats each line as a log entry in Elasticsearch. I am guessing my regex is not right but not sure. Any help would be appreciated. Thanks in advance!
Versions
- filebeat-6.3.2-1
- logstash-6.5.3-1
- elasticsearch-6.5.3-1

###################### Filebeat Configuration Example #########################
# This file is an example configuration file highlighting only the most common
# options. The filebeat.full.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html
#=========================== Filebeat prospectors =============================
filebeat.inputs:
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
- type: log
# Paths that should be crawled and fetched. Glob based paths.
paths:
#- /var/log/*.log
#- c:\programdata\elasticsearch\logs\*

# Include lines. A list of regular expressions to match. It exports the lines that are
# matching any regular expression from the list.
#include_lines: ["^ERR", "^WARN"]
# Exclude files. A list of regular expressions to match. Filebeat drops the files that

### Multiline options
# Mutiline can be used for log messages spanning multiple lines. This is common
# for Java Stack Traces or C-Line Continuation
# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#multiline.pattern: ^\[
#multiline.pattern: '^\<AUDIT'
multiline.pattern: '^\<AUDIT'
# Defines if the pattern set under pattern should be negated or not. Default is false.
multiline.negate: true
# Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
# that was (not) matched before or after or as long as a pattern is not matched based on negate.
# Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
multiline.match: after
multiline.flush_pattern: '</AUDIT>'
#================================ General =====================================
# The name of the shipper that publishes the network data. It can be used to group
# all the transactions sent by a single shipper in the web interface.
#name:
# The tags of the shipper are included in their own field with each
# transaction published.
#tags: ["service-X", "web-tier"]
# Optional fields that you can specify to add additional information to the
# output.
#fields:
# env: staging
#================================ Outputs =====================================
# Configure what outputs to use when sending the data collected by the beat.
# Multiple outputs may be used.
#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:
# Array of hosts to connect to.
# hosts: ["localhost:9200"]
# Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts
hosts: ["logstashserver:5044"]
# Optional SSL. By default is off.

#================================ Logging =====================================
# Sets log level. The default log level is info.
# Available log levels are: critical, error, warning, info, debug
#logging.level: debug
# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publish", "service".
