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.
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.
