Step 1: install filebeat

Reference: https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-installation.html

Step 2: filebeat directory description

Type Description Locationhome Home of the Filebeat installation. {extract.path} bin The location for the binary files. {extract.path} config The location for configuration files. {extract.path} data The location for persistent data files. {extract.path} / datalogs The location for the logs created by Filebeat. {extract.path} / logs

Step 3: filebeat configuration

The default profile is filebeat.yml

The content is:

# # 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 inputs = =

Filebeat.inputs:

# Each-is an input. Most options can be set at the input level, so

# you can use different inputs for various configurations.

# Below are the input specific configurations.

Type: log

# Change to true to enable this input configuration.

Enabled: false

# Paths that should be crawled and fetched. Glob based paths.

Paths:

/ var/log/.log

#-c:\ programdata\ elasticsearch\ logs\

# Exclude lines. A list of regular expressions to match. It drops the lines that are

# matching any regular expression from the list.

# exclude_lines: ['^ DBG']

# 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

# are matching any regular expression from the list. By default, no files are dropped.

# exclude_files: ['.gz $']

# Optional additional fields. These fields can be freely picked

# to add additional information to the crawled log files for filtering

# fields:

# level: debug

# review: 1

Multiline options

# Multiline 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: ^ [

# Defines if the pattern set under pattern should be negated or not. Default is false.

# multiline.negate: false

# 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

# = = Filebeat modules = =

Filebeat.config.modules:

# Glob pattern for configuration loading

Path: ${path.config} / 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

# = Elasticsearch template setting = =

Setup.template.settings:

Index.number_of_shards: 3

# index.codec: best_compression

# _ source.enabled: false

# = = 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

# = = Dashboards = =

# These settings control loading the sample dashboards to the Kibana index. Loading

# the dashboards is disabled by default and can be enabled either by setting the

# options here, or by using the-setup CLI flag or the setup command.

# setup.dashboards.enabled: false

# The URL from where to download the dashboards archive. By default this URL

# has a value which is computed based on the Beat name and version. For released

# versions, this URL points to the dashboard archive on the artifacts.elastic.co

# website.

# setup.dashboards.url:

# = = Kibana = =

# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.

# This requires a Kibana endpoint configuration.

Setup.kibana:

# Kibana Host

# Scheme and port can be left out and will be set to the default (http and 5601)

# In case you specify and additional path, the scheme is required: http://localhost:5601/path

# IPv6 addresses should always be defined as: https://[2001:db8::1]:5601

# host: "localhost:5601"

# Kibana Space ID

# ID of the Kibana Space into which the dashboards should be loaded. By default

# the Default Space will be used.

# space.id:

# = = Elastic Cloud = =

# These settings simplify using filebeat with the Elastic Cloud (https://cloud.elastic.co/).

# The cloud.id setting overwrites the output.elasticsearch.hosts and

# setup.kibana.host options.

# You can find the cloud.id in the Elastic Cloud web UI.

# cloud.id:

# The cloud.auth setting overwrites the output.elasticsearch.username and

# output.elasticsearch.password settings. The format is:.

# cloud.auth:

# = = 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: ["localhost:9200"]

# Optional protocol and basic auth credentials.

# protocol: "https"

# username: "elastic"

# password: "changeme"

#-Logstash output--

# output.logstash:

# The Logstash hosts

# hosts: ["localhost:5044"]

# Optional SSL. By default is off.

# List of root certificates for HTTPS server verifications

# ssl.certificate_authorities: ["/ etc/pki/root/ca.pem"]

# Certificate for SSL client authentication

# ssl.certificate: "/ etc/pki/client/cert.pem"

# Client Certificate Key

# ssl.key: "/ etc/pki/client/cert.key"

# = = Procesors = =

# Configure processors to enhance or manipulate events generated by the beat.

Processors:

Add_host_metadata: ~ add_cloud_metadata: ~

# = = Logging = =

# Sets log level. The default log level is info.

# Available log levels are: 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".

# logging.selectors: ["]

# = = Xpack Monitoring = =

# filebeat can export internal metrics to a central Elasticsearch monitoring

# cluster. This requires xpack monitoring to be enabled in Elasticsearch. The

# reporting is disabled by default.

# Set to true to enable the monitoring reporter.

# xpack.monitoring.enabled: false

# Uncomment to send the metrics to Elasticsearch. Most settings from the

# Elasticsearch output are accepted here as well. Any setting that is not set is

# automatically inherited from the Elasticsearch output configuration, so if you

# have the Elasticsearch output configured, you can simply uncomment the

# following line.

# xpack.monitoring.elasticsearch:

Step 4: filebeat grabs each service log and creates an index to store it in es with the name of the service

Write a filebeat-123.yml file as follows: filebeat.config: prospectors: path: / data/software/filebeat-6.5.1/conf/*.yml reload.enabled: true reload.period: 10soutput.elasticsearch: hosts: ["IP:9200"] index: "% {[fields] [out_topic]}" setup.template.name: "customname" setup.template.pattern: "customname-*" setup.template.overwrite: truelogging : level: debug combines the file ceshi.yml- type: logpaths:- / var/log/zookeeper/zookeeper.logtags: ["zookeeper"] exclude_files: [".gz $"] scan_frequency: 1sfields:server_name: hostname out_topic: "zookeeper_log" multiline:pattern: "^\\ S" match: after- type: logpaths:- / var/log/nginx/access.logtags: ["nginx"] exclude_files under the custom path : [".gz $"] scan_frequency: 1sfields:server_name: hostname out_topic: "nginx_log" multiline:pattern: "^\ S" match: after

In the above section, we crawled the zookeeper log and nginx log, and defined the index names as zookeeper_log and nginx_log, respectively.

Step 5: start filebeat and view the generated index in es

. / filebeat- e-c filebeat-123.yml

Check the index in es

Nginx_log and zookeeper_log indexes have been generated in es, and we look at the contents of the index in kibana

I see that there is already a real-time log running in the zookeeper_log index, so how to automatically update it.

Then we can see that the log is updated in real time 1 minute later on kibana.
