Sample filebeat.yml file for Prospectors ,Logstash Output and Logging Configuration


You can copy same file in filebeat.yml  and run  after making below change as per your environment directory structure and follow steps mentioned for Filebeat Download,Installation and Start/Run

  • Change on Prospectors section for your logs file directory and file name
  • Configure Multiline pattern as per your logs format as of now set as generic hopefully will work with all pattern
  • Change on Logstash Output section for Host ,Port and other settings if required
  • Change on logging directory as per you machine directory.

Sample filebeat.yml file

#=============Filebeat prospectors ===============

filebeat.prospectors:

# Here we can define multiple prospectors and shipping method and rules  as per #requirement and if need to read logs from multiple file from same patter directory #location can use regular pattern also.

#Filebeat support only two types of input_type log and stdin

##############input type logs configuration#####################

- input_type: log

# Paths of the files from where logs will read and use regular expression if need to read #from multiple files
paths:
- /opt/app/app1/logs/app1-debug*.log*
# make this fields_under_root as true if you want filebeat json out for read files in root.
fields_under_root: true

### Multiline configuration for handeling stacktrace, Object, XML etc if that is the case #and multiline is enabled with below configuration will shipped output for these case in #multiline

# The regexp Pattern that has to be matched. The example pattern matches all lines #starting with [DEBUG,ALERT,TRACE,WARNING log level that can be customize #according to your logs line format
#multiline.pattern: '^\[([Aa]lert|ALERT|[Tt]race|TRACE|[Dd]ebug|DEBUG|[Nn]otice|NOTICE|[Ii]nfo|INFO|[Ww]arn?(?:ing)?|WARN?(?:ING)?|[Ee]rr?(?:or)?|ERR?(?:OR)?|[Cc]rit?(?:ical)?|CRIT?(?:ICAL)?|[Ff]atal|FATAL|[Ss]evere|SEVERE|EMERG(?:ENCY)?|[Ee]merg(?:ency)?)'

# Default is false.Defines if the pattern match  should be negated or not.
#multiline.negate: true

# multiline.match define if pattern not match with above pattern where these line need #to append.Possible values  are "after" or "before".

#multiline.match: after

# if you will set this max line after these number of multiline all will ignore
#multiline.max_lines: 50
#=========Logstash Output Configuration=======================
output.logstash:
# Below enable flag is for enable or disable output module will discuss more on filebeat #module section.
#enabled: true

#  Here mentioned all your logstash server host and port to publish events. Default port #for logstash is 5044 if Logstash listener start with different port then use same here.
#hosts: ["logstashserver:5044"]

# It shows no of worker will run for each configure Logstash host.
#worker: 1

#Filebeat provide gzip compression level which varies from 1 to 9. As compression level #increase processing speed will reduce but network speed increase.By default #compression level disable and value is 0.
#compression_level: 3

# Default value is false.  If set to true will check status of hosts if unresponsive will send #to another available host. if false filebeat will select random host and send events to it.
#loadbalance: true

# Default value is 0 means pipeline disabled. Configure value decide of pipeline  batches #to send to logstash asynchronously and wait for response. If pipeline value is written #means output will blocking.
#pipelining: 0

#Filebeat use SOCKS5 protocol to communicate with Logstash servers. If any proxy #configure for this protocol on server end then we can overcome by setting below #details.

# SOCKS5 proxy URL
#proxy_url: socks5://userid:pwd@socks5-server:2233

# Default value is false means resolve host name resolution on  proxy server. If value is #set as true Logstash host name resolution locally for proxy.
#proxy_use_local_resolver: false

# Configure SSL setting id required for Logstash broker if SSL is configured
#ssl.enabled: true

# Optional SSL configuration options. SSL is off by default.
# List of root certificates for HTTPS server verifications

#SSK configuration is Optional and OFF by default . It required for server verification if #HTTPS root certificate .
#ssl.certificate_authorities: ["/app/pki/root/ca.pem"]

#Default value is full. SSL configuration verfication mode is required if SSL is configured #We can use value as 'none' for testing purpose but in this mode it can accept any #certificate.
#ssl.verification_mode: full

# List of supported/valid TLS versions. By default all TLS versions 1.0 up to
# 1.2 are enabled.

#By Default  it support all TLS versions after 1.0 to 1.2. We can also mentioned version in #below array
#ssl.supported_protocols: [TLSv1.0, TLSv1.1, TLSv1.2]

# Define path for certificate for SSL
#ssl.certificate: "/etc/pki/client/cert.pem"

# Define path for Client Certificate Key
#ssl.key: "/etc/pki/client/cert.key"

# If data is configured and shipped encrypted form. Need to add passphrase for #decrypting the Certificate Key otherwise optional
#ssl.key_passphrase: ''

# Configure encryption cipher suites to be used for SSL connections
#ssl.cipher_suites: []

# Configure encryption curve types for ECDHE based cipher suites
#ssl.curve_types: []
#====================Logging ==============================

# Default log level is info if set above or below will record top this hierarchy #automatically. Available log levels are: critical, error, warning, info, debug

logging.level: debug
# Possible values for selectors are "beat", "publish" and  "service" if you want to enable #for all select value as "*". This selector decide on command line when  start filebeat.
logging.selectors: ["*"]

# The default value is false.If make it true will send out put to syslog.
logging.to_syslog: false
# The default is true. all non-zero metrics  reading are output on shutdown.
logging.metrics.enabled: true

# Period of matrics for log reading counts from log files and it will send complete report #when shutdown filebeat
logging.metrics.period: 30s
# Set this flag as true to enable logging in files if not set that will disable.
logging.to_files: true
logging.files:
# Path of directory where logs file will write if not set default directory will home #directory.
path: /tmp

# Name of files where logs will write
name: filebeat-app.log
# Log File will rotate if reach max size and will create new file. Default value is 10MB
rotateeverybytes: 10485760 # = 10MB

# This will keep recent maximum log files in directory for rotation and remove oldest #files.
keepfiles: 7
# Will enable logging for that level only. Available log levels are: critical, error, warning, #info, debug
level: debug
