Hi,
I'm trying to parse some logs into Ealsticsearch from Filebeat.
The logs has a new line in them and their format is as follows:
# error 123
failed attempt because blah blah
I am changing the filter in the ingest pipeline for the system module. I have done this before for nginx module for some costume nginx logs and it works fine.
I tried a number of filters. These work on both the online grok builder and the one in DevTools in Kibana.
# %{GREEDYDATA:response}\n%{GREEDYDATA:error}
%{GREEDYDATA:response}\n%{GREEDYDATA:error}
However, the filter will always fail when ran through Filebeat. Furthermore, it also treats the logs are two separate entries when it's sent to Kibana. The first # error 123 will be a record by it self and then failed attempt because blah blah will be a record by itself and then obviously the filter will fail for both of them.
I can't use Logstash to send the data as I already have multiple logs from modules and custom logs going from Filebeat to Elasticsearch.
I tried adding the multiline options to system.yml but without any success.
multiline.pattern: '^#'
multiline.negate: true
multiline.match: after
Should I add this to system.yml or filebeat.yml? and is it even right?
Hi Kaiyan, thank you for your help.
I tried adding it to filebeat.yml but without any success.
Here is my filebeat.yml
####################### Filebeat Configuration Example #########################
# This file is an example configuration file highlighting only the most common
# options. The filebeat.reference.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
# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.
#============================= Filebeat modules ===============================
filebeat.inputs:
#- type: log
# enable: true
# paths:
# - /etc/test/error.log
multiline.pattern: "^# "
multiline.negate: true
multiline.match: after
filebeat.config.modules:
# Glob pattern for configuration loading
path: /etc/filebeat/modules.d/*.yml
# Set to true to enable config reloading
#reload.enabled: false
# Period on which files under path should be checked for changes
#reload.period: 10s
filebeat.overwrite_pipelines: true
#==================== Elasticsearch template setting ==========================
#
#setup.template.name: "filebeat-prod"
#setup.template.pattern: "filebeat-*"
#setup.template.settings:
# index.number_of_shards: 0
# index.number_of_replicas: 0
#================================ Outputs =====================================
# Configure what output to use when sending the data collected by the beat.
#-------------------------- Elasticsearch output ------------------------------
output.elasticsearch:
# Array of hosts to connect to.
hosts: ["${HOST}"]
# Optional protocol and basic auth credentials.
#protocol: "https"
username: "${USR}"
password: "${PWD}"
# index: "filebeat-prod-%{[beat.version]}-%{+yyyy.MM.dd}"
#================================ Logging =====================================
# Sets log level. The default log level is info.
# Available log levels are: critical, error, warning, info, debug
#logging.level: info
# 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".
#logging.selectors: ["*"]
UPDATE:
it works when I specify the path on filebeat.yml. it sets the multiline flag and negates it too.
I had to enable paths and I had my spaces wrong.
But when I set the path on the system.yml file it still picks the logs as two lines and says that the grok filter has failed.
Is there a way to add a grok filter to the filebeat.inputs module? I can find system.yml /usr/share/filebeat but i had no luck doing the same for filebeat.input.
